I am still not quite clear about the averaging of curvature. Sorry about that. could you tell me exactly which function I should use, and How should I choose each parameter? First, I get the curvature value of the pial surface, I think I should average the curvature value on the pial surface, perhaps not on white surface, I read help, It seems that It is smoothed on the white surface. How shoud I use the pial to smooth. And I want to keep format of the output file same to the lh.pial.H.crv , and the only difference is the scalar value is smoothed. Second, I want to obtain the absolute value of the scalar, In this step I will launch "mri_calc". Third, I want to resample and smooth it using kernel fwhm 20mm. Thanks! yczhang
