Hi,

Those aren’t surfaces – they are scalar fields over surfaces. You can visualize them by first loading any surface you want (e.g. lh.inflated), then use the “load curvature” or “load overlay” functions in freeview to visualize them on the surface.

Cheers

Hello, Fs

I can visualize the lh.white lh.sphere lh.pial and so on. But when I visulized the lh.sulc lh.thickness and  other feature files, the error will be displayed as follows: Failed to load surface.

Do you know how to visualize these feature files?

Looking forward to your reply
