## NAME

gt-splicesiteinfo - Show information about splice sites given in GFF3 files.

## SYNOPSIS

gt splicesiteinfo [option …] [GFF3_file …]

## DESCRIPTION

-seqfile [filename]

  set the sequence file from which to take the sequences (default: undefined)

-encseq [filename]

  set the encoded sequence indexname from which to take the sequences (default: undefined)

-seqfiles

  set the sequence files from which to extract the features use -- to terminate the list of sequence files

-matchdesc [yes|no]

  search the sequence descriptions from the input files for the desired sequence IDs (in GFF3), reporting the first match (default: no)

-matchdescstart [yes|no]

  exactly match the sequence descriptions from the input files for the desired sequence IDs (in GFF3) from the beginning to the first whitespace (default: no)

-usedesc [yes|no]

  use sequence descriptions to map the sequence IDs (in GFF3) to actual sequence entries. If a description contains a sequence range (e.g., III:1000001..2000000), the first part is used as sequence ID (III) and the first range position as offset (1000001) (default: no)

-regionmapping [string]

  set file containing sequence-region to sequence file mapping (default: undefined)

-addintrons [yes|no]

  add intron features between existing exon features (before computing the information to be shown) (default: no)

-o [filename]

  redirect output to specified file (default: undefined)

-gzip [yes|no]

  write gzip compressed output file (default: no)

-bzip2 [yes|no]

  write bzip2 compressed output file (default: no)

-force [yes|no]

  force writing to output file (default: no)

-help

  display help and exit

-version

  display version information and exit

File format for option -regionmapping:

The file supplied to option -regionmapping defines a “mapping”. A mapping maps the `sequence-region` entries given in the GFF3_file to a sequence file containing the corresponding sequence. Mappings can be defined in one of the following two forms:

    mapping = {
      chr1  = "hs_ref_chr1.fa.gz",
      chr2  = "hs_ref_chr2.fa.gz"
    }

or

    function mapping(sequence_region)
      return "hs_ref_"..sequence_region..".fa.gz"
    end

The first form defines a Lua (http://www.lua.org) table named “mapping” which maps each sequence region to the corresponding sequence file. The second one defines a Lua function “mapping”, which has to return the sequence file name when it is called with the `sequence_region` as argument.
