I was wondering if any one has had success merging BLAST databases from multiple references?
For a concrete example I have hg19 and a bunch of viral and bacterial genomes that all have been index separately but I want to do a single alignment to all of them. Is there a way I could say combine hg19, virus_A, virus_D and bacteria_X into a single database without having to regenerate? Since the problem could get combinatorial quickly and making a db with hg19 is time consuming I was wondering if there was a way around it.
This is similar to another ticket but asking for BLAST instead of alignment indexes.
