Off topic:Understanding Burrows–Wheeler Transform For Sequence Alignment

Question

[Madhan]

Hi,

I am trying to understand BWT for Short read sequence alignment. Though the Original paper (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2705234/pdf/btp324.pdf) explains it, i found it difficult to follow.

Do anybody have any recommendation on understanding the BWT along with Prefix trie for String Matching/ Short read sequence alignment problem.
