Dear Rudolph,

thank you very much for your reply. I used the load_mgh command in matlab for the preprocessed curv.mgh to create the absolute_curvature _values.mgh, which was successful.

Best regards,

Christoph

Dear all,

for a vertex-wise comparison of the mean curvature is there a possibility to change the signed curvature values from the

preprocessed

curv.mgh to unsigned (absolute) values for the glm?

The newest (i.e. dev) version of 'mris_calc' will do this:

$>mris_calc rh.curv abs

This will run an 'abs' (absolute value) function on each element in 'rh.curv'. Output is saved by default to 'out.crv'. You can specify a more meaningful output with '--output <someFile>', so

$>mris_calc --output rh.curv.abs rh.curv abs

Since this is only in the 'dev' tree, let me know if you'd like a binary.
