Hi All, apologies for what may be a basic issue, but I am having some problems with featquery. I am looking to use masks created on individual FSPGRs, however, when I try to enter this into featquery I get an error message. "Error - mask size doesn't match any of the images in the FEAT directory". I am entering the cope.feat files from my second level analysis (average across runs per participant). My understanding is that % signal change values should be extracted from these as they have had intensity normalisation applied. I have double checked and for each participant at the first-level analysis I have entered their BET stripped image as the "main structrual image" as well as an MNI template as the "standard space" image. Would anyone be able to point out where I am going wrong? Many thanks, Leah Leah Maizey PhD Student School of Psychology Cardiff University Park Place, Cardiff CF10 3AT email: [log in to unmask]
