New TSSP program for Recognition of human Pol II promoter region 
         and start of transcription 

Method description: 
Algorithm predicts potential transcription start positions by linear 
discriminant 
function combining characteristics describing functional motifs and 
oligonucleotide 
composition of these sites. TSSP uses file with selected factor binding sites 
from RegSite DB (Plants) developed by Softberry Inc. using literature data.

 You can try TSSP at:
  
       http://www.softberry.com/berry.phtml?topic=promoter

TSSP output: 
First line - name of your sequence; 
Second and Third lines - LDF threshold and the length of presented sequence 
4th line - The number of predicted promoter regions 
Next lines - positions of predicted sites, their 'weights' and TATA box 
position 
 (if found) 
Position shows the first nucleotide of the transcript (TSS position) 
After that functional motifs are given for each predicted region; (+) or (-) 
 reflects the direct or complementary chain; S... means a particular motif 
 identificator from the Wingender data base. 

For example:
