Hi All,

I am interested to understand how fimo (Find Individual Motif Occurrences ) works? In fact how PWM used as a prior information to find the probable motif occurrence in a DNA sequence? Unfortunately there is not enough description or computational method in FIMO original paper and I would be good if somebody can introduce me the original paper.

Thanks Morteza

This paper looks like an original one:

FIMO-description:

Some details about PWM:

Thanks .. It is very useful. But I meant the math behind motif discovery by having PWM and using HMM model.

I just asked your question in google.com

math behind motif discovery AND PWM AND HMM model

I hope you will find enough math in two links I've found (they are at the bottom). If not, try to ask the same question in

www.ncbi.nlm.nih.gov or www.scholar.google.com
