RSAT Matrix scan results help

Question

[datanerd]

Hi All,

Does anyone have any experience in using RSTA matrix SCAN (Scan a DNA sequence with a profile matrix using Enrichment of hits in the whole input sequence set as the output).

I am having difficult time interpreting the results. I am not sure what each column means. Can someone help me or guide me to a document that has the information.

Thanks in advance!
