28 **What it does**
29
30 This calls the Promoter 2.0 tool for prediction of eukaryotic PolII promoter sequences using a Neural Network (NN) model.
31
32 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):
33
34 1. Sequence identifier (first word of FASTA header)
35 2. Promoter position, e.g. 600
36 3. Promoter score, e.g. 1.063
37 4. Promoter likelihood, e.g. Highly likely prediction
38
39 The scores are classified very simply as follows:
40
41 ========= ========================
42 Score Description
43 --------- ------------------------
44 below 0.5 ignored
45 0.5 - 0.8 Marginal prediction
46 0.8 - 1.0 Medium likely prediction
47 above 1.0 Highly likely prediction
48 ========= ========================
49
50 Internally the input FASTA file is divided into parts (to allow multiple processors to be used), and the raw output is reformatted into this tabular layout suitable for downstream analysis within Galaxy.
