This is a web server that enables the analysis of multiple DNA sequences using sets of Position Weight Matrices from the JASPAR and TRANSFAC databases, using multiple scanning algorithms. (The use of the TRANSFAC matrices for analyses is free for users from non-profit organizations only. Commercial users have to license the TRANSFAC database [Disclaimer].)
