But honestly, before you begin you should really first read some
review/overviews of NGS protocols so you can do some informed analysis
(if I recall there were a few in Nature(something) around the end of
last year, start of this year(?))
That having been said, if you're just working on a fastq file and want
to stay in the bioconductor realm, have a look at the ShortRead
