显示 更早的评论
Hi there. Pls help me resolve an issue I cant find a solution for: I have a two 3D matrixes with the same dimentions( 288*288*80)off nii files. I want to search for nonzero positions on the first matrix and use thoses positions to go through the second matrix, and do a sum of the values located on those positions . How can I do it? Regards
