computer 17 November 2011 | 2 Comments

I recently had a need to speedily parse through 8GiB+ .fastq text files to calculate a simple statistic of genomic data. My initial “pfastqcount” implementation in Ruby worked fine, but with many files to process took longer than I had hoped in addition to consuming an alarming amount of CPU.
