ProbABEL v0.3.0 release

With the new year comes good news: ProbABEL v0.3.0 has been released today.

This release marks the end of a lot of work done on the internals of ProbABEL, which was started earlier this year by Maarten Kooyman. The most important thing a user will notice is an approximately four-fold speed increase when running palinear with the --mmscore option as well as possible speed increases in other use cases as well.
In his e-mail to the development mailing list of 2012-12-21 Maarten explains his work in more detail, including a few graphs of the speed gains.

Major bugs fixed in this release:

  • Fixed bug #2436: doesn't overwrite output file (as it used to do before 0.2.2). This bug was introduced with the possibility of using SNP dosages/probabilities that are split into (sub-chromosomal) chunks.

Were to get it:

  • The source package can be found on the GenABEL website at:
  • Users of Ubuntu (or one of its derivative distributions like Kubuntu or Linux Mint) can install the latest ProbABEL release from the GenABEL PPA (Personal Package Archive) by following these steps:
