Sometimes we just want to count the number of voxels whose values are more than zero.
My friend showed me a script which can do that easily. SPM functions are used, so you need to install SPM first.
%%%%%countvx.m %a script which counts voxels whose values are more than zero. file = spm_select; vol = spm_vol(file); img = spm_read_vols(vol); sum(img(:)>0)
If you change the value of the last line from 0 to 0.1, you will count the number of voxels whose values are more than 0.1.
