Hello group, I'm about to upgrade to TopSpin on our acquisition computers. I'm thinking about using CentOS, which is supposed to be identical to RedHat Enterprise in every way except for the redhat logos. Has anyone tried this? Does anyone know which version of CentOS would be best? Enterprise and CentOS are up to version 5.1 now, but I'm worried that the later versions won't be compatible with TopSpin. Bruker supports Enterprise 3 and 4 with TopSpin 2.1. thanks in advance, -Robert ---------------------------------------- Robert Peterson, Ph.D. Facility Manager MBI-DOE Biomolecular NMR Facility UCLA Dept. of Chemistry and Biochemistry phone: (310)825-1816 fax: (310)825-0982 peterson@mbi.ucla.edu ----------------------------------------
