Software repositories (or repo's) are weblocations that host software installation files. You can plug-in into these repo's to install software. Software sources are very powerful. Whenever a PPA gets updated, you can get their latest versions. Always add only trusted sources.

Bielefeld Bioinformatics research group has decided to put their software in a PPA, a Personal Package Archive. This is a special type of repository.

You can add this repo to your system.

  1. Search on the PPA website for bioinformatics
  2. You get a list of PPA repo's containing bioinformatics software. Find Bielefeld Bioinformatics.
