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
function combining characteristics describing functional motifs and
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:


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
  (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:

  Length of sequence-      5871
  Thresholds for TATA+ promoters -  0.02, for TATA-/enhancers -  0.04
