Hi, When i tried to install ROCKS 3.1.0 onto a cluster compute node. It will return me a screen saying: Missing Package You have specified that the package 'Fasta' should be installed. This package does not exist. Would you like to continue or abort your installation. If I select 'abort' the system will reboot again. But i did not specified any package to be installed. What had happened? Thanks for the reply.
