Well, you got it, but in the most complicated way possible if you created a file. MIRA tells you: > " Could not find FASTA quality file 454_muestra2_backbone_in.fasta.qual, > using default values for these reads. ... and it does not stop. Meaning it's not an error. MIRA always *tries* to load qualities for the backbone. But unlike for normal reads, it does not stop when there are none. It simply uses the defaults and tells you that. That's all. Don't waste your disk space, using -SB:bbq is entirely sufficient for your needs. BTW, I'd recommend using a backbone quality of 30 or 40 at most.
