I'm very happy with `sassy grep` now!
If you ever need to inspect what's in your data, please try and let me know how it goes :)
Of course, it's fast: >1GB/s when using multiple threads.

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.

Coming soon to K2: a feature for querying many K2 indexes as though they're a single index. Highly useful if the index you want to query is too big to build and/or fit in RAM.

Just published an interactive article about a magical algorithm known as the Burrows-Wheeler Transform, which powers sequence alignment tools like bowtie and bwa: sandbox.bio/concepts/bwt
It's also notoriously unintuitive so I'm hoping this article helps you build that intuition.

Thanks for organizing this! It has been incredibly frustrating to see these delays. We spent 5 weeks running a workshop for our incoming graduate students on writing a GRFP fellowship, and now we're wondering if they'll even be able to submit anything.
