Dear Friends does exist a BioC package to work on GEO soft files? I would to get expression data and other infos from this file. This should be a nice thing before starting to write a parser to do that.... Any of you had occasion to manage soft files?? Thanks you -- "Raffiniert ist der Herr Gott, aber boshaft ist Er nicht." --- Dr. Edoardo Saccenti FiorGen Pharmacogenomics Foundation CERM Nuclear Magnetic Resonace Research Center Scientific Pole - University of Florence Via Luigi Sacconi n? 6 50019 Sesto Fiorentino (FI) tel: +39 055 4574193 fax: +39 055 4574253 saccenti@cerm.unifi.it www.cerm.unifi.it
