- Transcription Factor Binding Sites are sites in the genome where transcription factor proteins bind to the genome as part of transcription initiation or repression.
- TFBS  is also a package of BioPerl-compatible Perl modules that are used for transcription factor binding site detection and analysis.
Example TFBS usage
- Count or Weight matrix (based on Malcolm Cook's post)
#!/usr/bin/perl -w use strict; use TFBS::PatternGen::SimplePFM; my @sequences = <>; chomp @sequences; print TFBS::PatternGen::SimplePFM->new(-seq_list=>\@sequences)->pattern->rawprint;
