Then I indexed the genome in color space and mapped the reads. My mapping didn't work and that made me think if my files are in wrong format.

I don't at the moment, sorry.
I haven't stumbled on cutadapt before, thanks for pointing it out.
Unfortunately I'm not sure how to help you smoke out your problem. Are
you sure you have the correct adapter sequence you are trimming out?
If you expect your reads to be of a minimum length, maybe you can just
include the first X basepairs of the reads and try to align it that
way? (maybe there's something wrong with the 3' trimming)
