Hi Donatas, The surface file, that correspond to one particular subject, is probably fine as far as it has the same geometry (number of vertices and faces) as all other subjects.
For the area file, PALM expects it to be the average area across all subjects, as opposed to the actual areas for all subjects. To fix, just average the areas. I think the option -metric-reduce of wb_command should do it. Hope this solves the problem!
