Question about DRAGEN

[betasheet45]

For those more experienced with DRAGEN, is there a recommended way or tool to validate my code and make sure it's accurate? Any tips on debugging DRAGEN scripts would be super helpful!

For DRAGEN, I've found that simply running small test cases with known outputs is the most reliable way to validate accuracy.
For debugging, dragen --list-steps is gold for understanding the pipeline, and checking the individual step logs in the output directory usually points you right to the problem.
Hope this helps!

Use the dragen_validate tool to get a more detailed output and validation.

Great idea! The best way to tackle this is by running some small test cases that you already know the results for. That way, you can check out your logs and the MetricsOutput files to see what's going on. Also, don't forget about the --first-tile-only flag, it's a handy little trick that can really speed up your debugging process. So, what kind of script are you diving into?

One of my colleagues was really frustrated with a DRAGEN script until he decided to use a known control dataset. That's when everything clicked, and the errors he was seeing finally made sense. He compared it to flipping on a light switch. Using logs and some small test cases ended up saving him hours of work.
