Generally I thought this was a great piece. I was a little annoyed that he kept referring to "BAM" files as holding his genomic information. e.g.: "He wanted to get his own BAM file and study it."

BAM is just a format that describes the way that short chunks of DNA are aligned to a reference file of other DNA. It would be a BAM file whether you are talking about someone's genome or an experiment where the readout was a sequencing assay.

To hear how off that sounds, consider the following: "He wanted to get his own m4a file to listen to it." "She wanted to get her own xlsx file to calculate her expenses"

Perhaps its a small gripe, but why not just say "raw data" or "genomic sequence" either of which would be more accurate and not cause some of us to cringe!
