That is correct. We don’t recommend WM and CSF regression necessarily, as it doesn’t do much (when the masks are eroded by 2 2mm voxels from the greymatter as these are). If they are not eroded they behave more like global signal regression, which is controversial for removing a portion of the neural signal.

I've looked through the HCP release documentation and manually inspected the images I suspect to be the masks, but would appreciate confirmation that I've located the correct files. The files I've located can be accessed through the following paths: https://hcp-openaccess.s3.amazonaws.com/HCP_1200/100307/MNINonLinear/ROIs/CSFReg.2.nii https://hcp-openaccess.s3.amazonaws.com/HCP_1200/100307/MNINonLinear/ROIs/WMReg.2.nii If these aren't the correct files, I would greatly appreciate the path to the proper masks. Thank you. _______________________________________________ HCP-Users mailing list [email protected]<mailto:[email protected]> http://lists.humanconnectome.org/mailman/listinfo/hcp-users _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
