Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
htslib
- Gentoo -Os vs -O3 application startup time?
- Does anyone know of a repository for actual genetic data?

Pigz: A parallel implementation of gzip for multi-core machines
There is another nice multi-core gzip based library called BGZF[1]. It is commonly used in bioinformatics. BGZF has the added advantage that it is block compressed with built in indexing method to permit seeking in compressed files.

Tips for scalable workflows on AWS
In contrast, processing can start immediately and only transfer what is necessary if tooling can read bytes of data directly from Amazon S3. Tools based on htslib can do this, so you can run something like:

Software Development Project
Another idea is add in reading cloud data natively e.g. htslib which samtools relies on can read s3 directly. https://github.com/samtools/htslib

Interested in Bioinformatics / C pair-programming opportunity / learning / portfolio project.
Greetings! I'm a bioinformatics software dev in San Francisco and I'm looking for others interested in working on a high-performance genetic data analysis project. The project is in C, using https://github.com/samtools/htslib.

ffi-bitfield
I'm working on a bioinformatics-related binding called ruby-htslib. htslib makes heavy use of bit fields throughout the library, so supporting bit fields is inevitable.

Anyone use DRAGEN-GATK?
If you haven’t heard of it already you may want to check out https://github.com/bwa-mem2/bwa-mem2 which is a faster version of bwa-mem. I’ve been using it for a while now and found it to be quite stable, same results as the original and the speed improvement is nice.

Software Development Project
I’ve recently switched to bwa mem2 and the speed increase is nice for what is basically a drop in replacement (after a bit of validation to make sure that was true). https://github.com/bwa-mem2/bwa-mem2
