Introduction

This service online provide an efficient and accurate algorithm to evaluate the statistical significance of DNA motifs. Given motifs described in IUPAC or PWM(Position Weight Matirx) format, the program can calculate the EXACT p-value allowing multiple occurrences of motifs under an order-1 Markov background model. The current service only allows single sequence and users should provide the parameters of the backgraound model. It will be improved soon.
For questions about this web site or if you encounter any problems, don't hesitate to contact Zhang Jing. We are open to any suggestions or remarks concerning this web interface.

DNA Sequences

DNA Sequences should be submitted in Fasta format (example).


Check this box if you like to include both strands in the analysis.

Motifs

Upload your own set of motifs in the required format (example0,example1,example3):

Markov Model

Upload the parameters of the order-1 markov model of the background sequences in the required format (example):
