Hi all,

I am trying to run VLSM with lesion masks we have hand traced. We have converted the .nii files to .mat files and have created the correct excel file for running the VLSM in NiiStat. However when we run the script it doesn't add masks from R and L sides together but analyses them separately. 

How can we before running the analysis, flip the masks to all be on one side? 

Thank you!
