Another way to filter the sulc is:
$>mris_calc -o lh.sulc.pos lh.sulc gte 0
which filters 'lh.sulc' and only lets values that are greater than or
equal to 0 through
Hi, experts,
I am interested in only the positive sulc and would like to make group
analysis of the postive sulc values. Hence I would like to mask off the
negative values (as the lh.sulc file has both positive and negative value).
Before making group analysis, I have to resample and smooth t
You can use make a mask out of the sulc using mri_binarize. This will
result in a surface value file with 1s and 0s. You can then run
mris_fwhm to smooth the sulc, passing it the sulc mask. Note:
mri_surf2surf and mris_fwhm are redundant in that they can both smooth
