Dear reader,

Thank you for following our work.

DNA analysis is often shared as a VCF file, or variant call format file. We recently made our internal tool, VCFheader, public. It has passed 500 users this month across the R package and macOS/Linux command-line versions.

We have just added a browser version for people who want a faster, lower-tech way to inspect a VCF header.

Release page:

https://switzerlandomics.ch/technologies/vcfheader/browser/

Drop in a VCF or VCF.gz file and VCFheader shows the reference, samples, filters, INFO and FORMAT fields, and other header metadata in a structured report. It reads the header metadata only, not your private data. The file is processed within your own browser.

You can also download a PDF report or presentation slides for sharing.

VCFheader is free and open source.

Bug reports from early users are very welcome.

Thank you again for your support.

Best wishes,
Dylan
