transfac2meme [options] <matrix file>
Convert a TRANSFAC 'matrix.dat' file into a MEME motif file suitable for use with MEME Suite programs.
The IUPAC letter at the end of each matrix line is optional. The motif name is taken from the "ID" line, but may also be taken from the "AC" or "NA" line if requested using an optional parameter (below). The "NA" name, if present, is used as the secondary motif name, separated by a space from the primary name, except when it is requested to be the primary name. Note that dollar signs are converted to underscores in the motif name.
Each TRANSFAC(-like) entry must end with either an "XX" or "//" line.
If your file is in TRANSFAC-like format you must specify option -use_name (see below).
|-use_acc||Use the TRANSFAC accession (AC field) instead of the TRANSFAC ID (ID field) as the motif identifier.|
|-use_name||Use the TRANSFAC name (NA field) instead of the TRANSFAC ID (ID field) as the motif identifier. This option is required if the motif file is in TRANSFAC-like.|
|-ids||ID file||Keep only the motifs identified in the ID file.||Keep all motifs.|
|-species||species name||Keep only motifs with this species name.||Keep all motifs.|
