TRAP

TRAP is a program that detects the binding affinity of a Transcription Factors(TFs) for a DNA sequence.
Given a list of Gene sequences (or Ensembl IDs), the program calculates the binding affinity of a
list of TF's (Transfac matrices) for the supplied Genes.
The user is returned a list of TF's ranked by affinity score for each gene supplied.
purge_seq

Mask redundant fragments in a sequence.
