I first heard of nim discovering mosdepth, a fantastic program to extract coverage information from alignments. I just thought it was a bizarre choice and never thought again about it…until also Heng Li blogged about fast programming languages for bioinformatics.
I started my best journey in a programming language.
My first Perl Module has been an N50 calculator, that to me is sort of an Hello World considering I spent most of my PhD trying to improve one (lovely) assembly.
I tried to make its bundled utility, called simply n50, useful both for interactive sessions and for scripts, and the utility itself has been my first tool packaged in bioconda.
