Issues with legacy_blast.pl when using psicoffee mode

[fer...@gmail.com]

Hello group,

I have a transmembrane protein dataset, for which I want to use psicoffee for alignment. After browsing and digging around, I came up with the command:

t_coffee Pl-B2_s5_cdh70.fsa -mode psicoffee -blast_server LOCAL -protein_db /home/fer/Desktop/test/uniref90_TM/uniref90_TM.fasta

but I get:

INPUT FILES
Input File (M) proba_pair
Input File (S) Pl-B2_s5_cdh70.fsa  Format fasta_seq

I have already manually installed the package containing legacy_blast.pl, which I have also added to $PATH (I checked and it's dicoverable). Also, the database was formatted with makeblastdb.

So, any ideas on what may be going on here? Thanks in advance!
