+**What it does**
+
+This calls the TMHMM v2.0 tool for prediction of transmembrane (TM)  helices in proteins using a hidden Markov model (HMM).
+
+The input is a FASTA file of protein sequences, and the output is tabular with six columns (one row per protein):
+
+ 1. Sequence identifier
+ 2. Sequence length
+ 3. Expected number of amino acids in TM helices (ExpAA). If this number is larger than 18 it is very likely to be a transmembrane protein (OR have a signal peptide).
+ 4. Expected number of amino acids in TM helices in the first 60 amino acids of the protein (Exp60). If this number more than a few, be aware that a predicted transmembrane helix in the N-term could be a signal peptide.
+ 5. Number of transmembrane helices predicted by N-best.
+ 6. Topology predicted by N-best (encoded as a strip using o for output and i for inside)
+
+Predicted TM segments in the n-terminal region sometime turn out to be signal peptides.
+
+One of the most common mistakes by the program is to reverse the direction of proteins with one TM segment.
+
+Do not use the program to predict whether a non-membrane protein is cytoplasmic or not. 
+
+**Notes**
+
+The raw output from TMHMM v2.0 looks like this (six columns tab separated):

+
+In order to make it easier to use in Galaxy, the wrapper script simplifies this to remove the redundant tags, and instead adds a comment line at the top with the column names:
