I am a bit confused. I am a new Rocks user and just installed the biobrew roll. I was expecting that the packages contained in the roll would be installed in a ready to run fashion. So for instance after installing the roll, I was expecting to be able to run any of the contained programs such as Blast or MrBayes with little or no additional effort. Instead all I can find are the RPM files for the biobrew programs. None of the executables seem to be there. Am I suppose to install each of the packages individually using rpm -i ? I hate to be so dense but ........ Thanks Paul
