error when making blast db

[merytouceda]

Hi!

I am trying to make a blast db with the NCyc100.faa.gz file (I also tried with the 95 and got the same error) so that I can blast it outside of the perl executable you provide. I basically unzip the file and then run makeblastdb, However I can't make the database because i get the following error:

`BLAST Database creation error: Error: Duplicate seq_ids are found:
LCL|39946.BGIOSGA039077-PA

`
Has this issue happened before?
Thank you!
