## 1.0 SUMMARY

Remove redundancy from DHF files

## 2.0 INPUTS & OUTPUTS

SEQNR removes redundancy from DHF files (domain hits files) or other files of sequences. A directory of DHF files (all sequences) is read and a directory of new DHF files (non-redundant sequences) plus (optionally) a second directory of DHF files (redundant sequences) is written. Optionally, up to two further directories of filter sequences may be read: these are considered in the redundancy calculation but never appear in the output files. Typically, one of the further directories contains DHF files each with a single sequence and the other DAF files (domain alignment files) each containing a sequence alignment, but any sequence(s) may be given. Each filter directory must contain a file for each file in main input directory and the files must have the same base name. For example, sequences from "family.dhf" and "family.daf" are considered for the input DHF file "family.hits".
Redundancy is removed at either (i) a user-defined threshold of sequence similarity or (ii) a user-defined range of threshold sequence similarity. Files of sequences in any supported format may be read and written (not just DHF or DAF files). A log file is also written.
The path for all files (input and output) are specified by the user. The file extensions are set in the ACD file. The name of the log file is set by the user.

## 3.0 INPUT FILE FORMAT

The format of the domain hits file is described in SEQSEARCH documentation.
The format of the domain alignment file is described in DOMAINALIGN documentation.
If other sequences or sequence sets (aligned or unaligned) are used as input, all of the common file formats are supported.

## 4.0 OUTPUT FILE FORMAT

The format of the domain hits file is described in SEQSEARCH documentation.

## 6.0 USAGE

### 6.1 COMMAND LINE ARGUMENTS

    Remove redundancy from DHF files.
    Version: EMBOSS:6.6.0.0

       Standard (Mandatory) qualifiers (* if not always prompted):
      [-dhfinpath]         dirlist    [./] This option specifies the location of
                                      DHF files (domain hits files) (input). A
                                      'domain hits file' contains database hits
                                      (sequences) with domain classification
                                      information, in the DHF format (FASTA or
                                      EMBL-like). The hits are relatives to a SCOP
                                      or CATH family and are found from a search
                                      of a sequence database. Files containing
                                      hits retrieved by PSIBLAST are generated by
                                      using SEQSEARCH.
       -[no]dosing         toggle     [Y] This option specifies whether to use
                                      singlet sequences (e.g. DHF files) to filter
                                      input. Optionally, up to two further
                                      directories of sequences may be read: these
                                      are considered in the redundancy calculation
                                      but never appear in the output files.
    *  -singletsdir        directory  [./] This option specifies the location of
                                      singlet filter sequences (e.g. DHF files)
                                      (input). A 'domain hits file' contains
                                      database hits (sequences) with domain
                                      classification information, in the DHF
                                      format (FASTA or EMBL-like). The hits are
                                      relatives to a SCOP or CATH family and are
                                      found from a search of a sequence database.
                                      Files containing hits retrieved by PSIBLAST
                                      are generated by using SEQSEARCH.
       -[no]dosets         toggle     [Y] This option specifies whether to use
                                      sets of sequences (e.g. DHF files) to filter
                                      input. Optionally, up to two further
                                      directories of sequences may be read: these
                                      are considered in the redundancy calculation
                                      but never appear in the output files.
    *  -insetsdir          directory  [./] This option specifies location of sets
                                      of filter sequences (e.g. DAF files)
                                      (input). A 'domain alignment file' contains
                                      a sequence alignment of domains belonging to
                                      the same SCOP or CATH family. The file is
                                      in clustal format annotated with domain
                                      family classification information. The files
                                      generated by using SCOPALIGN will contain a
                                      structure-based sequence alignment of
                                      domains of known structure only. Such
                                      alignments can be extended with sequence
                                      relatives (of unknown structure) by using
                                      SEQALIGN.
       -mode               menu       [1] This option specifies whether to remove
                                      redundancy at a single threshold % sequence
                                      similarity or remove redundancy outside a
                                      range of acceptable threshold % similarity.
                                      All permutations of pair-wise sequence
                                      alignments are calculated for each set of
                                      input sequences in turn using the EMBOSS
                                      implementation of the Needleman and Wunsch
                                      global alignment algorithm. Redundant
                                      sequences are removed in one of two modes as
                                      follows: (i) If a pair of proteins achieve
                                      greater than a threshold percentage sequence
                                      similarity (specified by the user) the
                                      shortest sequence is discarded. (ii) If a
                                      pair of proteins have a percentage sequence
                                      similarity that lies outside an acceptable
                                      range (specified by the user) the shortest
                                      sequence is discarded. (Values: 1 (Remove
                                      redundancy at a single threshold % sequence
                                      similarity); 2 (Remove redundancy outside a
                                      range of acceptable threshold % similarity))
    *  -threshold          float      [95.0] This option specifies the % sequence
                                      identity redundancy threshold. The %
                                      sequence identity redundancy threshold
                                      determines the redundancy calculation. If a
                                      pair of proteins achieve greater than this
                                      threshold the shortest sequence is
                                      discarded. (Any numeric value)
    *  -threshlow          float      [30.0] This option specifies the % sequence
                                      identity redundancy threshold (lower limit).
                                      The % sequence identity redundancy
                                      threshold determines the redundancy
                                      calculation. If a pair of proteins have a
                                      percentage sequence similarity that lies
                                      outside an acceptable range the shortest
                                      sequence is discarded. (Any numeric value)
    *  -threshup           float      [90.0] This option specifies the % sequence
                                      identity redundancy threshold (upper limit).
                                      The % sequence identity redundancy
                                      threshold determines the redundancy
                                      calculation. If a pair of proteins have a
                                      percentage sequence similarity that lies
                                      outside an acceptable range the shortest
                                      sequence is discarded. (Any numeric value)
      [-dhfoutdir]         outdir     [./] This option specifies the location of
                                      DHF files (domain hits files) of
                                      non-redundant sequences (output). A 'domain
                                      hits file' contains database hits
                                      (sequences) with domain classification
                                      information, in the DHF format (FASTA or
                                      EMBL-like). The hits are relatives to a SCOP
                                      or CATH family and are found from a search
                                      of a sequence database. Files containing
                                      hits retrieved by PSIBLAST are generated by
                                      using SEQSEARCH.
       -dored              toggle     [N] This option specifies whether to retain
                                      redundant sequences. If this option is set a
                                      DHF file (domain hits file) of redundant
                                      sequences is written.
    *  -redoutdir          outdir     [./] This option specifies the location of
                                      DHF files (domain hits files) of redundant
                                      sequences (output). A 'domain hits file'
                                      contains database hits (sequences) with
                                      domain classification information, in the
                                      DHF format (FASTA or EMBL-like). The hits
                                      are relatives to a SCOP or CATH family and
                                      are found from a search of a sequence
                                      database. Files containing hits retrieved by
                                      PSIBLAST are generated by using SEQSEARCH.
       -logfile            outfile    [seqnr.log] This option specifies the name
                                      of SEQNR log file (output). The log file
                                      contains messages about any errors arising
                                      while SEQNR ran.

       Additional (Optional) qualifiers:
       -matrix             matrixf    [EBLOSUM62] This option specifies the
                                      residue substitution matrix that is used for
                                      sequence comparison.
       -gapopen            float      [10.0 for any sequence] This option
                                      specifies the gap insertion penalty. The gap
                                      insertion penalty is the score taken away
                                      when a gap is created. The best value
                                      depends on the choice of comparison matrix.
                                      The default value assumes you are using the
                                      EBLOSUM62 matrix for protein sequences, and
                                      the EDNAFULL matrix for nucleotide
                                      sequences. (Floating point number from 1.0
                                      to 100.0)
       -gapextend          float      [0.5 for any sequence] This option specifies
                                      the gap extension penalty. The gap
                                      extension, penalty is added to the standard
                                      gap penalty for each base or residue in the
                                      gap. This is how long gaps are penalized.
                                      Usually you will expect a few long gaps
                                      rather than many short gaps, so the gap
                                      extension penalty should be lower than the
                                      gap penalty. (Floating point number from 0.0

[-dhfinpath]
(Parameter 1)

dirlist

This option specifies the location of DHF files (domain hits files) (input). A 'domain hits file' contains database hits (sequences) with domain classification information, in the DHF format (FASTA or EMBL-like). The hits are relatives to a SCOP or CATH family and are found from a search of a sequence database. Files containing hits retrieved by PSIBLAST are generated by using SEQSEARCH.

Directory with files

./

-[no]dosing | toggle | This option specifies whether to use singlet sequences (e.g. DHF files) to filter input. Optionally, up to two further directories of sequences may be read: these are considered in the redundancy calculation but never appear in the output files. | Toggle value Yes/No | Yes

-singletsdir

directory

This option specifies the location of singlet filter sequences (e.g. DHF files) (input). A 'domain hits file' contains database hits (sequences) with domain classification information, in the DHF format (FASTA or EMBL-like). The hits are relatives to a SCOP or CATH family and are found from a search of a sequence database. Files containing hits retrieved by PSIBLAST are generated by using SEQSEARCH.

Directory

./

-[no]dosets | toggle | This option specifies whether to use sets of sequences (e.g. DHF files) to filter input. Optionally, up to two further directories of sequences may be read: these are considered in the redundancy calculation but never appear in the output files. | Toggle value Yes/No | Yes

-insetsdir

directory

This option specifies location of sets of filter sequences (e.g. DAF files) (input). A 'domain alignment file' contains a sequence alignment of domains belonging to the same SCOP or CATH family. The file is in clustal format annotated with domain family classification information. The files generated by using SCOPALIGN will contain a structure-based sequence alignment of domains of known structure only. Such alignments can be extended with sequence relatives (of unknown structure) by using SEQALIGN.

Directory

./

-mode

list

This option specifies whether to remove redundancy at a single threshold % sequence similarity or remove redundancy outside a range of acceptable threshold % similarity. All permutations of pair-wise sequence alignments are calculated for each set of input sequences in turn using the EMBOSS implementation of the Needleman and Wunsch global alignment algorithm. Redundant sequences are removed in one of two modes as follows: (i) If a pair of proteins achieve greater than a threshold percentage sequence similarity (specified by the user) the shortest sequence is discarded. (ii) If a pair of proteins have a percentage sequence similarity that lies outside an acceptable range (specified by the user) the shortest sequence is discarded.

1 | (Remove redundancy at a single threshold % sequence similarity)
2 | (Remove redundancy outside a range of acceptable threshold % similarity)

1

-threshold | float | This option specifies the % sequence identity redundancy threshold. The % sequence identity redundancy threshold determines the redundancy calculation. If a pair of proteins achieve greater than this threshold the shortest sequence is discarded. | Any numeric value | 95.0
-threshlow | float | This option specifies the % sequence identity redundancy threshold (lower limit). The % sequence identity redundancy threshold determines the redundancy calculation. If a pair of proteins have a percentage sequence similarity that lies outside an acceptable range the shortest sequence is discarded. | Any numeric value | 30.0
-threshup | float | This option specifies the % sequence identity redundancy threshold (upper limit). The % sequence identity redundancy threshold determines the redundancy calculation. If a pair of proteins have a percentage sequence similarity that lies outside an acceptable range the shortest sequence is discarded. | Any numeric value | 90.0

[-dhfoutdir]
(Parameter 2)

outdir

This option specifies the location of DHF files (domain hits files) of non-redundant sequences (output). A 'domain hits file' contains database hits (sequences) with domain classification information, in the DHF format (FASTA or EMBL-like). The hits are relatives to a SCOP or CATH family and are found from a search of a sequence database. Files containing hits retrieved by PSIBLAST are generated by using SEQSEARCH.

Output directory

./

-dored | toggle | This option specifies whether to retain redundant sequences. If this option is set a DHF file (domain hits file) of redundant sequences is written. | Toggle value Yes/No | No

-redoutdir

outdir

This option specifies the location of DHF files (domain hits files) of redundant sequences (output). A 'domain hits file' contains database hits (sequences) with domain classification information, in the DHF format (FASTA or EMBL-like). The hits are relatives to a SCOP or CATH family and are found from a search of a sequence database. Files containing hits retrieved by PSIBLAST are generated by using SEQSEARCH.

Output directory

./

-logfile | outfile | This option specifies the name of SEQNR log file (output). The log file contains messages about any errors arising while SEQNR ran. | Output file | seqnr.log
Additional (Optional) qualifiers
-matrix | matrixf | This option specifies the residue substitution matrix that is used for sequence comparison. | Comparison matrix file in EMBOSS data path | EBLOSUM62
-gapopen | float | This option specifies the gap insertion penalty. The gap insertion penalty is the score taken away when a gap is created. The best value depends on the choice of comparison matrix. The default value assumes you are using the EBLOSUM62 matrix for protein sequences, and the EDNAFULL matrix for nucleotide sequences. | Floating point number from 1.0 to 100.0 | 10.0 for any sequence

-gapextend

float

This option specifies the gap extension penalty. The gap extension, penalty is added to the standard gap penalty for each base or residue in the gap. This is how long gaps are penalized. Usually you will expect a few long gaps rather than many short gaps, so the gap extension penalty should be lower than the gap penalty.

Floating point number from 0.0 to 10.0

0.5 for any sequence

### 8.1 GLOSSARY OF FILE TYPES

FILE TYPE | FORMAT | DESCRIPTION | CREATED BY | SEE ALSO

Domain hits file

DHF format (FASTA-like).

Database hits (sequences) with domain classification information. The hits are relatives to a SCOP or CATH family (or other node in the structural hierarchies) and are found from a search of a discriminating element (e.g. a protein signature, hidden Markov model, simple frequency matrix, Gribskov profile or Hennikoff profile) against a sequence database.

SEQSEARCH (hits retrieved by PSIBLAST). SIGSCAN (hits retrieved by sparse protein signature). LIBSCAN (hits retrieved by various types of HMM and profile).

N.A.

Domain alignment file

DAF format (CLUSTAL-like format with domain classification information).

Contains a sequence alignment of domains belonging to the same SCOP or CATH family. The file is annotated with domain family classification information.

DOMAINALIGN (structure-based sequence alignment of domains of known structure).

DOMAINALIGN alignments can be extended with sequence relatives (of unknown structure) to the family in question by using SEQALIGN.

None

## 9.0 DESCRIPTION

Redundancy in a database or other collection of sequences occurs when one or more similar sequences are present. The inclusion of very similar sequences in certain analyses will introduce undesirable bias. For example, a family may possess 100 sequences in the sequence database, but 90 of these might be essentially the same sequence, e.g. very close relatives or mutations of a single sequence. Although 100 sequences are known, the family only contains 11 sequences that are essentially unique. For many applications it is desirable or even essential to remove redundant sequences from a set in order to produce a smaller set that is representative of the whole. SEQNR removes redundancy from an input file of sequences, either at a single threshold of sequence similiarty (e.g. 40%) or within a threshold range of sequence similiarty (e.g. 40% - 70%).

## 10.0 ALGORITHM

Redundancy is calculated for each DHF file in the input directory in turn. The procedure is as follows. 1. Create a list of sequences from the main input directory. 2. Add sequences from both filter directories (if specified) to list but mark them up (they are considered in the redundancy calculation but never appear in the output files). 3. Identify redundant domains. 4. Write non-redundant domains to main output directory. 5. If specified, write redundant domains to output directory.

## 12.0 DIAGNOSTIC ERROR MESSAGES

The log file might contain the following messages:
embHitlistReadFasta call failed in seqnr (By default SEQNR expects a domain hits file in the main input directory and the first (singlets) filter directory. This message is given if some other type of sequence file is given. Its not really an error, just a warning).
Empty input file my.file (This is given if the main input file 'my.file' did not contain any sequences. No output file is generated for this file.)
Empty singlets filter file my.file (This is given if the singlets filter file 'my.file' did not contain any sequences. An output file is still generated for this file.)
Empty sets filter file my.file (This is given if the sets filter file 'my.file' did not contain any sequences. An output file is still generated for this file.)
ajDmxScopalgRead call failed in seqnr my.file (By default SEQNR expects a domain alignment file in the second (sets) filter directory. This message is given if some other type of sequence sets file (called 'my.file') is given. Its not really an error, just a warning).
