The command I was using was : wb_command -cifti-reduce Brodmann_Bilateral_IFG.dlabel.nii MAX Brodmann_Bilateral_IFG_Merged.dscalar.nii
Where Brodmann_Bilateral_IFG.dlabel.nii contains two labels. Again, this command does not seem to the production of a label file directly. Thanks On Sep 27, 2016, at 6:20 PM, Michael F.W.

It seems this function is meant to perform an operation to produce a scalar file, but what is produced when I use MAX for example is just a scalar file where the value for the key each labeled region had in the label file is not the value in that scalar file. so BA44 was 65, BA45 was 66, and now there are two regions with values 65 and 66. What I am trying to do is to merge regions together into one region as a label file to use as a single mask. Is this possible with this function? I’m sorry if I’m missing something here.

For these kinds of files, that means it isn't reducing across space. MAX is one of the options it can calculate, and for binary ROIs, that is equivalent to boolean OR, which is what we want. The commands are generally written to perform small, specific actions, such that they could be suitable for multiple tasks. Tim On Tue, Sep 27, 2016 at 4:49 PM, Michael F.W.

If I have a cifti with BA44 and BA45 for example and I want those two regions to be merged into one, how would -cifti-reduce do that? Wouldn’t it be more suited to calculating something (i.e. mean, mode, etc.) within each of those parcels?
