Hi Gwenaelle,
see info below and design.mat attached. One thing I noticed is that (due to some nomenclature error) I had more files in the "struc" folder than in the higher order directory: Basically, I had run step one but single digit subject ids were wrong ("3" instead of "03", "4" instead of "04" and so on, for one of my two groups) which I had changed and rerun step one. It appears that it had simply added the new, then correctly named cases, so I basically had duplicates of the same file but with different filenames. I have now deleted those excessive cases from the struc folder and also some from the slicedir directory, but the problem still persists, I guess because there are probably some files whose names I cannot readily identify as referring to those excessive files. Does this mean I better rerun things alltogether?
I appreciate your help! Thanks and best regards,
hannah
