Hi Andrés,

it just takes one sequence as input.

Btw. you can see this if you look what the emboss programs say with -help.

> backtranseq -help
   Standard (Mandatory) qualifiers:
  [-sequence]          sequence   (Gapped) protein sequence filename and
                                  optional format, or reference (input 

If it says "sequence" than it takes just one sequence as input.

> infoseq -help
   Standard (Mandatory) qualifiers:
  [-sequence]          seqall     (Gapped) sequence(s) filename and 
                                  format, or reference (input USA)

If you see "seqall"  than the program can work on more than one sequence.

For your problem you can either use "seqretsplit" to split up our file 
into individual sequences or you can write a script which iterates through 
the multiple fasta file with "skipseq" and sends its output to
