|  | const RascalMCES::RascalOptions & | rascalOptions,
|  | const SynthonSpaceSearchParams & | params = SynthonSpaceSearchParams() )

Parameters

  query | : query molecule
  rascalOptions | RASCAL options. The similarityThreshold value in the rascalOptions will be used rather than params.similarityCutoff, but params.fragSimilarityAdjuster will be used to adjust the threshold for the fragment comparisons.
  params | : (optional) settings for the search

Returns
  : the hits as a SearchResults object.

## readDBFile()

void RDKit::SynthonSpaceSearch::SynthonSpace::readDBFile | ( | const std::string & | inFilename,
|  | int | numThreads = 1 )

Reads from a binary DB File in our format.

Parameters

  inFilename | the name of the file to read.
  numThreads | number of threads to use in reading. If negative, adds the number to the number of hardware threads available.

## readStream()

void RDKit::SynthonSpaceSearch::SynthonSpace::readStream | ( | std::istream & | is,
|  | bool & | cancelled )

## readTextFile()

void RDKit::SynthonSpaceSearch::SynthonSpace::readTextFile | ( | const std::string & | inFilename,
|  | bool & | cancelled )

Parameters

  inFilename | name of the file containing the synthon-based library.

The original format is: all lines are tab-separated first line:SMILES synton_id synton# reaction_id Note the spelling "synton" from the original paper/example file. Subsequent lines have a single reagent e.g. OCC([U])=NN=[Np] 1-1 0 triazole-1 C1CCCC1N([Pu])[U] 2-1 1 triazole-1 CC1CCN(C1)C(=[Np])[Pu] 3-1 2 triazole-1

Other acceptable formats are as above, but with a 5th column "release": SMILES synton_id synton# reaction_id release

or a comma-separated equivalent of the first format: SMILES,synton_id,synton_role,reaction_id but with the 3rd column named differently but with the same meaning. The formatting of the first 2 formats has been relaxed such that any whitespace may be used as the field separator, but a tab is tried first so that a tab-separated file may have spaces in the columns.

Attachment points are U, Np, Pu and Am for up to 4 synthons per reaction. A product is created by taking a synthon from each synton# value and combining by replacing matching trans-uranic elements and replacing them with a direct bond of the appropriate type. A more (for RDKit) conventional connection flag of isotope labelled dummy atoms is also accepted ([1*] etc.). Throws a std::runtime_error if it doesn't think the format is correct, which it does by checking that the first line is as above and subsequent lines have appropriate number of fields. If it receives a SIGINT, returns cancelled=true.

## substructureSearch() [1/2]

SearchResults RDKit::SynthonSpaceSearch::SynthonSpace::substructureSearch | ( | const GeneralizedSubstruct::ExtendedQueryMol & | query,
|  | const SubstructMatchParameters & | matchParams = SubstructMatchParameters(),
|  | const SynthonSpaceSearchParams & | params = SynthonSpaceSearchParams() )

Perform a substructure search with the given generalized query molecule across the synthonspace library. Duplicate SMILES strings produced by different reactions will be returned.

Parameters

  query | : query molecule
  params | : (optional) settings for the search

Returns
  : the hits as a SearchResults object.
