=head1 DESCRIPTION
-This is a program for predicting the secondary structure of a multiple sequence alignment (by default) or a protein sequence
-(with the -seq option). The input file can be stored in 3 formats: FASTA, MSF, or BLC.
-For the single sequence the program does all the PSI-BLAST searching, preparing PSSM and HMM profiles and predicting the
-secondary structure with Jnet. For the multiple sequence alignment only the HMM profile, created from the alignment, is used in Jnet.

-
-The input file is a FASTA file with one sequence only.

=item -output <FILEPREFIX>
A prefix to the filenames created by Jpred, defaults to the value set by -sequence/-in.
