Re: [HCP-Users] ROI cluster centers to surface grayordinates

2018-03-01 Thread Timothy Coalson
Unfortunately, it is worse than that - even ignoring the individual variability issue (which should not be ignored), a small change in MNI coordinate can jump from one bank of a sulcus to the other, so having only the center coordinate of a cluster makes this a badly posed problem (and thus

[HCP-Users] ROI cluster centers to surface grayordinates

2018-03-01 Thread Manasij Venkatesh
Hi, I have a set of ROI cluster center coordinates in MNI space. My goal is to create similar ROI clusters to use with HCP data. I understand there's no true equivalent in terms of surface grayordinates but what would be the best way to find their approximate position on the surface? Is this the
