Google groups

To be informed about updates, get technical support, make feature requests, and/or engage in other public communication about PLINK-related matters, you'll want to join one or two of our Google groups.

  • The plink2-announce group is the low-traffic choice, with nothing but major release announcements.
  • The plink2-users group is the general discussion and technical support forum. With luck, the archives will become useful over time as solutions to the most common issues accumulate. Release announcements will be crossposted here; we may also solicit feedback re: upcoming features.
  • plink2-dev is for those working with the source code. If you want to implement something new and/or perform a useful refactoring, this is a good place to discuss it, especially if you want to see your work merged into the main codebase; we'll try to answer your questions in enough detail to enable you to finish your job.

To privately communicate with the development team (e.g. you have a potentially sensitive bug report), send email to wdist@cog-genomics.org.
