We will be getting data from human whole exome sequencing done on Illumina GAIIx. I am planning to put together a pipeline to align (BWA?)(optional as we may get the sequence already aligned)|variant detection (Samtools?)|variant classification-deleteriousness prediction(something like SIFT/PolyPhen)|. I know that there are various options out there but I would like to know based on your experiences what the best collection of these tools is? If you had the chance to start from scratch what kind of a pipeline would you put together? I also know that big sequencing centers have their in house tool sets for these for squeezing the last drop but what is available to the general public is what I am looking for.
