Hello Anderson,
Thank you so much for a clarification. I think we are comfortable with the contrast weights at this stage, however, we are a little unclear about the "-whole" option. What would it do for a groupXtime interaction? Do we need to use that in addition to the "-within" option. Do the following options work for our case of groupXtime interaction with unequal groups?
palm -i all_RD_skeletonised.nii -o results_RD -m mean_FA_skeleton_mask.nii -d model.mat -t model.con -f model.fts -eb Longitudinal.csv -T -tfce2D -n 10000 -corrcon -whole -within -save1-p
Also, the language in the PALM wiki seems to imply that the -eb file could have more than a single column. Could you please elaborate on that? (for the -within and -whole options it says: "if the file has a single column…."
Thanks again!
-Marina
