Is it possible to find the positions of mismatches if using mathPDict to align patterns to a sequence of reference ?

Question

[Aurelie MLB]

Hello,

I am using the bioconductor function matchPDict to align quickly a big number of small patterns to the genome. I am authorizing 2-3 mismatches. I get the result with the position for the match of my patterns but I also would like to identify easily the position of the mismatches with the aligments. Is it possible to do that ? Is there a pre-implemented function? I found one for matchPattern but not for matchPDict..

Many thanks!
