Hi SunSun, I ran a search today and got the same error. I was using a bovine database that I downloaded quite a while ago. So I downloaded the latest version today, appended the CRAP database to it and then ran it through the decoy utility to create a concatenated forward and reversed sequence database. Subsequent searches with the new database completed without error.
I can only presume the older database became corrupted somehow. I don't know of a utility that will validate the integrity of a database. If you know regex or maybe perl you could write a script to look for characters that are not part of the amino acid code. For me the expedient solution was to download a fresh version of the database.
