Total ESTs    Total number of ESTs associated with promoter sequence by high stringency BLAST. Expect value used for Blast was e-21, additional filtering practically removed matches of expect > e-30.  Positive 5-prime ends    Number of 5' ESTs ends mapping in the region +30 to - 5 relative to transcription start point. sample 1    sample 2    sample 3     Overshooting 5-prime ends    Number of longer 5' ESTs ends. sample 1    sample 2    sample 3    sample 4     Minimal positive : overshooting ratio    Ratio of 5' ESTs ends mapping in the region +30 to -20 versus longer 5' ESTs ends. Low values sugest that the downstream promoter is very weak or the transcription start poin is missmapped.  Minimal upstream sequence lenght    Retrieve upstream promoter sequences of certain minimal length. The sequences range in size from 60 to 1000 bp, average lenght is near 750 bp  Minimal downstream sequence lenght    The immediatelly downstream transcribed sequence was used as query for the high stringency Blast search.  Promoter pos.    Minus one nucleotide placement in the parent sequence. This is the most 3' nucleotide in the PRESTA upstream sequence.  Expressed in    Looks for the occurence of certain words in the tissue or organ source of Ests coupled to the particular promoter.  Upstream seq.    Maximum number of bases to report from the upstream sequence. The 5' end of the reported sequence is located upstream, the 3' end maps to nucleotide -1.  Downstream seq.    Maximum number of bases to report from the downstream sequence. The 5' end of the reported sequence is located at nucleotide +1.
