I just installed the Diamond Protein Alignment Algorithm (http://ab.inf.uni-tuebingen.de/software/diamond/) yesterday and the first step before the alignment is to set up a database. The input for generating a database should be a FASTA file containing protein sequences. I created a db-File from a FSTA file containing multiple Protein sequences and it worked out (meaning Diamond did the job without any errors). But after that if I want to start aligning samples to the databse I always get the error: incompatible database version. Has anyone of you expirience with this program?
