Hi Mariano, A yum repo for Fedora Core hasn't (yet) been set up, but since Rocks is a RedHat-derivative, you may find that the BioBrew/Rocks binaries work with certain versions of Fedora. As an example, you can add the following to your yum configuration file to ignore the release version and platform variables (e.g., i386) associated with BioBrew/Rocks: --------8<-------- [biobrew] name=BioBrew baseurl=http://biobrew.bioinformatics.org/rpm/rocks/4/i386/ gpgcheck=0 -------->8-------- Your Fedora's yum system will then read the BioBrew/Rocks repo (only bioinformatics & HPC RPMS are in there) when looking for packages.
