[EMBOSS] uniq sequences on a list

[Fernando Martinez]

Hi, I am trying to retrieve sequences from a multi-fasta file were there are
identical sequences and i want to extract only the ones in my list, how can
I do that?
Example:

Multi.fasta file:

>seq1
atataga...
>seq2
ttatggttca..
[...]
>seq1
atataga...
[...]

and my list is:

Multi.fasta:seq1
Multi.fasta:seq2

When I run "seqret @list -out out.fasta"

I retrieve :
>seq1
atataga...
>seq2
ttatggttca...
>seq1
atataga...

And I only want to take seq1 an seq2, not two times seq1!!

thanks
