I found 10,000 variants. The lab expected 5. Did I mis-call indels? Is there a batch effect? Did someone accidentally use the mouse reference genome again? (It happened once. Once.)
You can have the cleanest pipeline, the most parallelized code, and a server with 1TB of RAM. But if you don’t understand the biological question, you’re just moving bytes around.
I’ve learned the hard way that a single misplaced flag in cutadapt can turn your precious RNA-seq reads into biological confetti. My morning ritual? Coffee. htop to see if my server is crying. And grep to make sure my adapter indices didn’t cross-contaminate. david bioinfo

Welcome to bioinformatics. It’s not just running BLAST on a Sunday afternoon. I found 10,000 variants
Hi! I’m David. Ask me what I do, and you’ll get a different answer depending on the day.
Here’s a structured blog post tailored for someone named working in bioinformatics . It’s written to be engaging, professional, and relatable to peers in computational biology. Title: From Command Lines to Chromosomes: A Day in the Life of David, Bioinformatician Is there a batch effect
The hardest part of my job isn’t the code—it’s the interpretation .
