Sorry for the basic question, but I would like to poll the list for information on Yum Repos. Which do you use?, which do you like? what should be added? and where? etc. etc. I was tempted to crosspost to the bioclusters list, but I will hold off doing that to see if I hit the bulls-eye here ;-) The ones I know about are 'BioLinux' and the stuff produced by Joe Landman (is he on this list?), and I just found via Google 'BIOrpms' and 'BIOPACKAGES.NET'; http://www.biolinux.org/ http://downloads.scalableinformatics.com/ http://apt.bea.ki.se/ http://www.biopackages.net/ Possibly a good place to start a list is here; http://bioinformatics.org/BIO-NIX/mediawiki/index.php/Yumrepository Thanks for any feedback, Dan.
