... Dear Wei, Thanks for your response. I was going to use Rsubread with a small(ish) data set on a desktop with a little more memory than the standard laptop. I like the approach behind Rsubread and I wanted to do some comparisons with other aligners on small data sets before making a choice. Of co ...
