How can I recover a gene accession number from a gene title list?

Question

[ary.dantas161189]

We have a tanscriptome data obtained from RNA-seq and we are starting to annotate the full results generated through the process.

For this, we ran a blastx against the nr-database, and accidentaly, we did not put the "sseqid" command on the line. Therefore our sheet with the results cannot be annotated using David database.

Do you know a way to retrieve the seqid using subject titles list?

Thanks!

Yikes! It may be easier to re-do the blast than try to figure this out backwards.

lol! It took 2 weeks to run the whole thing, we are trying to avoid another waste of time if possible

You could parse that information out of the nr fasta file that you can find here, in that case. Hopefully you are going to be able to map the titles to accession cleanly (some may be similar).
