 The input is a FASTA file of nucleotide sequences (e.g. upstream regions of your genes), and the output is tabular with five columns (one row per promoter):
 
- 1. Sequence identifier (first word of FASTA header)
- 2. Promoter position, e.g. 600
- 3. Promoter score, e.g. 1.063
- 4. Promoter likelihood, e.g. Highly likely prediction
