This is the primary technical support group for PLINK 1.9 and 2.0 users. Please post full .log file(s) when asking for troubleshooting help and/or reporting a bug.

It was previously also intended as a venue for other discussion of general interest to PLINK users, but there's too much technical-support traffic for that to work well. Instead:

- Major release announcements (including major bugfixes) are posted to the plink2-announce Google group. They will still be cross-posted to plink2-users.

- Feature requests and well-informed bug reports can be made at https://github.com/chrchang/plink-ng/issues . (But if you've encountered behavior where you're unsure whether it's a bug or a feature you're unaware of, plink2-users is better.) Feature requests can range from little bits of interface cleanup, to full calculations which cannot currently be performed at satisfactory speed/scale with existing software. Unexpected and unwanted incompatibilities between PLINK 1.9 and PLINK 1.07's interface count as bugs.

- Remarks on our documentation are welcome either here or on GitHub. We'll try to rewrite/redesign any parts that are confusing.
