I had some inquiries in the past regarding how the SKIM routines (all-vs-all comparison) of MIRA works. Well, a nice paper has just appeared which describes almost exactly the principles of the SKIM algorithm ... except it's called SlideSort, it's not from me and is not related in any way to MIRA: http://bioinformatics.oxfordjournals.org/content/27/4/464.short Now I just ask myself why in 2003 I thought that SKIM was to similar to SSAHA to make a paper out of it. Oh well. B.
