VCFALLELICPRIMITIVES(1)

NAME

vcfallelicprimitives - Converts stdin or given VCF file and reduces alleles.

SYNOPSIS

vcfallelicprimitives

DESCRIPTION

vcfallelicprimitives converts stdin or given VCF file to tab-delimited format,

Realign reference and alternate alleles with WFA, parsing out the primitive alleles into multiple VCF records. New records have IDs that reference the source record ID. Genotypes are handled. Deletion alleles will result in haploid (missing allele) genotypes.

Note that this tool is considered legacy and will emit a warning! Use vcfwave instead.

  Options

-h, –help
    shows help message and exits.

See more below.

EXIT VALUES

0   Success

not 0
    Failure

EXAMPLES

    >>> head("vcfallelicprimitives -h",29)
    >
    usage: ./vcfallelicprimitives [options] [file]
    >
    WARNING: this tool is considered legacy and is only retained for older
    workflows.  It will emit a warning!  Even though it can use the WFA
    you should use [vcfwave](./vcfwave.md) instead.

    options:
        -a, --algorithm TYPE    Choose algorithm (default) Wave front or (obsolete)
                                Smith-Waterman [WF|SW] algorithm
        -m, --use-mnps          Retain MNPs as separate events (default: false).
        -t, --tag-parsed FLAG   Annotate decomposed records with the source record
                                position (default: ORIGIN).
        -L, --max-length LEN    Do not manipulate records in which either the ALT or
                                REF is longer than LEN (default: unlimited).
        -k, --keep-info         Maintain site and allele-level annotations when
                                decomposing.  Note that in many cases,
                                such as multisample VCFs, these won't be
                                valid post decomposition.  For biallelic
                                loci in single-sample VCFs, they should be
                                used with caution.
        -d, --debug             debug mode.

vcfallelicprimitives picks complex regions and simplifies nested alignments. For example:

    >>> sh("grep 10158243 ../samples/10158243.vcf")

After aligning it reduces into two records with variant alleles

    10158243:ACCCCCA/A
    10158243:ACCCCCACCCC/A
    10158243:ACCCCCACCCCCA/A
    10158243:ACCCCCACCCCCAC/A

    10158255:AC/A
    10158255:ACC/A

and adjusts the genotypes accordingly splitting into two records using the original (but arguably OBSOLETE) SW algorithm:
