[EMBOSS] Does seqret have limitations ?

I don't receive any error from seqret, it simply stops just as if it was
The file is not bigger than 2Gb:
$ du -sk file.gbk
Even with the cat command you sent me, I only get 17143 sequences formatted
in GCG format. (it is the same if I try to convert in fasta format)
$ grep -c "Check" file.gcg
$ grep -c "LOCUS" file.gbk
$ seqret file.gbk -osformat fasta -outseq test
Reads and writes (returns) sequences
$ grep -c ">" test
If anybody has an idea...
Thanks a lot,

Seqret is not limited by number of files. I routinely pass the whole of
EMBL through seqret and it works fine. What error do you get when seqret
stops? Could it just be that there is a malformed entry part way through
Is the file you are trying to convert >2Gb in size? If so this could be the
reason for the failure rather than seqret being limited by the number of
sequences. In this case though I thought that the failure would happen when
the file was first opened and not after a certain number of sequences had
If the problem is a large file you might be able to get round this by using
a pipe to get information into seqret. Try
cat your_genbank_file.gb | seqret -filter -osf gcg > your_gcg_file.gcg
This should work as long as your OS version of cat and your shell can handle
Hope this helps
