No. You missed that you need a data set directory to under rawData, e.g. rawData/NameOfMyDataSet/Mapping50K_Hind240/. See for instance page 'Setup: Quick Summary Of Required File Structure' [http://aroma-project.org/node/79]. See also http://aroma-project.org/setup/. > > > > Then I did : > > > > ds <- doCRMAv1("R:/work/breast/breast data files/MYC/rawData", > chipType="Mapping50K_Hind240") You should never have to specify a path/directory when using the aroma framework, instead it should look something like: ds <- doCRMAv1("NameOfMyDataSet", chipType="Mapping50K_Hind240"); Since the aroma framework nows where to look for data files, it is all automagically taken care of.
