Description
This script calls PSIPRED to carry out secondary structure prediction for the given sequence. The sequence is read from a file which should contain only the one-letter amino acid sequence either on a single or on multiple lines.
In order for this script to work, PSIPRED and BLAST/PSI-BLAST along with the
recent sequence databases (nr, swissprot, pdbaa) should be installed.
The location of the PSIPRED installation can be provided through the environment variable PSIPREDDIR.
