[Bioc-sig-seq] finding the final nucleotide of trimmed reads

[joseph franklin]

Hi,

I've been trimming adapters from reads using trimLRPatterns.  The resulting, trimmed set contains a heterogenous mix of widths: from ~18-35 nt.  Can anyone guide me toward an elegant way to find the nucleotide composition of the final (right-most) cycle for each of the trimmed reads?

Many thanks,
Joe Franklin
