Testing CERN ROOT RNTuple for genomic data - need review

Hi r/bioinformatics,

I'm a student working on migrating genomic alignments to ROOT's(CERNs data storage) RNTuple format. Built a SAM converter and region query tool, would be grateful for your review.

GitHub: https://github.com/compiler-research/ramtools

Need feedback on:

• Does it handle your SAM files correctly?
• What BAM features are must-haves?
• What should I add to make it actually useful?

I wanted to make something which bridge the drawbacks of other formats(CRAM/BAM) and would be useful for the community.This is built on the previous TTree format work(https://github.com/GeneROOT/ramtools).
I have updated the readme section with all the performance improvements we have got.

Thanks!
