What is TFM-Explorer?
TFM-Explorer (Transcription Factor Matrix Explorer) is a program for analysing regulatory regions of eukaryotic genomes.
It takes a set of coregulated gene sequences, and search for locally overrepresented transcription factor biding sites.
The algorithm proceeds in two steps:
- scans sequences for detecting all potential transcription factor binding sites, using weight matrices from JASPAR or TRANSFAC (disclaimer)
- extracts significant clusters (region of the input sequences associated with a factor) by calculated a score function
