Dear Prof.Smith, I really appreciate your help. I like to compare the second rs-fmri scan (from two different days) of the same subject.
1.when i open MSMAII_hp2000_clean.dtseries in WB, I get also a layer "dynconn", for example: rfMRI_REST1_LR_Atlas_MSMAII_hp2000_clean.dynconn.nii Are those group average? 2. It is recommended in the HCP Users FAQ: "demean and normalize the individual timeseries." wb_command -cifti-math '(x - mean) / stdev' <output> I am confused because it is writing demean and normalize. (zscore include demean, am I missing something?). My design is "within", so should I only apply demean? or because it is in a different day I should apply zscore? 3. I believe that statistically there are not enough time points in one scan to use all grayordinates. Thus, I will need to chose parcels/ROI. What is the best parcels/ROI I can use? (I like to focus on the attentional network, working memory and DMN) Is there an easy way to get those ROIs from the tasks? Thank you Tali _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users
