Hi - I'm wondering (before I try and damage remote equipment)
when running wb_command -cifti-math is it necessary that the cifti(s) fit into RAM memory? what I want to do is take a very large dconn.nii file, and binarize it such that all non-zero entries are 1 and all 0 entries stay 0. this is, obviously, an intermediate step to something else (tracking stats from vertex seeds). In an ideal world I'd also like to divide the value in each cell by another cifti of the same dimensions. if -cifti-math is able to avoid RAM (like cifti-reduce) then great. If not I need another way or I risk disrupting the university cluster. the basic task is to replace all non-zero entries with 1 without requiring more than say 1/10 of the file size in RAM. if that is not possible then, if we call the binarised cifti above "A" then the output of -cifti-reduce A.dconn.nii SUM obtained by any means would be great and a big help obviously there is more detail to the problem/questions that might help. But I'm trying not to explicitly be "unsupported" at this point in case the question can be answered in a "supported" way. best, Colin
