Dear FSL-gurus, I’m currently trying to reproduce parts of the Human Connectome Project HCP-1200 subject PTN release using the template scripts from „scripts1200“ provided by Steve Smith. I originally posted to the hcp-users mailing list and was asked to post here (https:[log in to unmask]). Unfortunately, I’m having trouble to run MELODIC v3.15 from FSL 5.0.11 on the groupPCA eigenmaps, which I downloaded from db.humanconnectome.org. The error is: Image Exception : #4 :: Incompatible number of mask positions and matrix columns I ran melodic \ -i (...)/groupPCA/HCP_S1200_812_rfMRI_MSMAll_groupPCA_d4500_Eigenmaps_recon2.dtseries.nii \ -o (...)/groupICA/groupICA_3T_HCP1200_MSMAll_d25.ica \ -d 25 --nobet --nomask --bgthreshold=-1e10 --Oall --report --CIFTI -v The complete output is below. In comparison to the original script, I added the --CIFTI switch, because otherwise melodic complained about not being able to read the groupPCA file. Any suggestions? (Are the groupPCA files from the website actually the files I want to use?)
