Following ish's `filter` and bqtools' `grep`, Sassy now also has initial support for grep and filter!

Grep mode shows all matches, grouped per record, and is meant for human consumption.
Filter mode prints full matching (or non-matching) records to stdout or output files.

Really exciting that the preprint on Barbell, a new demultiplexer, is finally out!
It's the first tool that builds on Sassy, the approximate-DNA-searching tool that @rickbitloo.bsky.social and myself developed earlier this year, specifically with this application in mind.

Barbell Resolves Demultiplexing and Trimming Issues in Nanopore Data https://www.biorxiv.org/content/10.1101/2025.10.22.683865v1

Around 10% of your Nanopore reads (SQK-RBK114) are incorrectly trimmed. Here is why, and how our new tool Barbell solves it:
