Search for of consensus patterns with statistical estimation.
The method is based on statistical estimation of expected number of a nucleotide consensus pattern in a given sequence [1-2]. It uses Nsite formatted datafile, which can include any set of consensus sequences of functional motifs. In current version this file consists of older release of Transfac® sequences (ver. 3.4, 1998), composite elements  and a set of additional functional motifs. Commercial use of the program requires Transfac database license. If pattern is found with expected number significantly less than 1, it can be supposed that the analysed sequence possesses the pattern's function. In the output of Nsite we can see a pattern, its position in the sequence, accession number, ID, Description of motif and binding factor name from the original database if exist.
