## Function

Scan DNA sequences for transcription factors

## Description

jaspscan scans one or more DNA sequences for transcription factor binding sites from the JASPAR database. Matches are searched for using fast sequence word-matching, optionally allowing mismatches. Because the binding sites are so small, there will be many spurious (false positive) matches.

An output file is written with information on the matches, including sequence ID and accession number, the start and end positions of the match in an input sequence and the sequence of the region where a match has been found. Binding factor information, where available, is given at the end of the matches for each matching entry.

## Usage

       Standard (Mandatory) qualifiers:
      [-sequence]          seqall     Nucleotide sequence(s) filename and optional
                                      format, or reference (input USA)

                                      JASPAR matrix set. You can specify
                                      individual matrices by giving
                                      their names with commas between then, such
                                      as:
                                      'ma0001.1,ma0015*'.
                                      The case of the names is not important. You
                                      can specify a file of
                                      matrix names to read in by giving the name
                                      of the file holding the
                                      matrix names with a '@' character in front
                                      of it, for example,
                                      '@matrix.list'.
                                      Blank lines and lines starting with a hash
                                      character or '!' are ignored and all other
                                      lines are concatenated together with a comma
                                      character ',' and then treated as the list
                                      of enzymes to search
                                      for.
                                      An example of a file of matrix names is:

                                      list. Matrices are specified in the same way
                                      as for the

string

The name 'all' reads in all matrix files from the selected JASPAR matrix set. You can specify individual matrices by giving their names with commas between then, such as: 'ma0001.1,ma0015*'. The case of the names is not important. You can specify a file of matrix names to read in by giving the name of the file holding the matrix names with a '@' character in front of it, for example, '@matrix.list'. Blank lines and lines starting with a hash character or '!' are ignored and all other lines are concatenated together with a comma character ',' and then treated as the list of enzymes to search for. An example of a file of matrix names is: ! my matrices ma0001.1, ma0002.1 ! other matrices ma0010.1 ma0032* ma0053.1

## Input file format

jaspscan reads one or more nucleotide sequences.

The input is a standard EMBOSS sequence query (also known as a 'USA').

Major sequence database sources defined as standard in EMBOSS installations include srs:embl, srs:uniprot and ensembl

Data can also be read from sequence output in any supported format written by an EMBOSS or third-party application.

The input format can be specified by using the command-line qualifier `-sformat xxx`, where 'xxx' is replaced by the name of the required format. The available format names are: gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw), dasgff and debug.

See: http://emboss.sf.net/docs/themes/SequenceFormats.html for further information on sequence formats.

'tembl:m23100' is a sequence entry in the example nucleic acid database 'tembl'

## Output file format

The output is a standard EMBOSS report file.

The results can be output in one of several styles by using the command-line qualifier `-rformat xxx`, where 'xxx' is replaced by the name of the required format. The available format names are: embl, genbank, gff, pir, swiss, dasgff, debug, listfile, dbmotif, diffseq, draw, restrict, excel, feattable, motif, nametable, regions, seqtable, simple, srs, table, tagseq.

See: http://emboss.sf.net/docs/themes/ReportFormats.html for further information on report formats.

By default the report is in 'seqtable' format.

## Data files

EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA.

To see the available EMBOSS data files, run:

    % embossdata -showall

To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run:

    % embossdata -fetch -file Exxx.dat

Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata".

The directories are searched in the following order:

- . (your current directory)
- .embossdata (under your current directory)
- ~/ (your home directory)
- ~/.embossdata

The EMBOSS JASPAR transcription site files are stored in directory 'data/JASPAR/*' under the EMBOSS installation directory.

These files must first be set up using the program 'jaspextract'. Running 'jaspextract' may be the job of your system manager.

The data files are stored in the JASPAR directory of the standard EMBOSS data directory. The subdirectory names are:

- JASPAR_CORE Core files
- JASPAR_FAM Family files
- JASPAR_PHYLOFACT Phylogeny files

The column information is described on the JASPAR home page http://jaspar.genereg.net/
