We have put together an automated structural connectome pipeline based on this thread "Beginner: Connectome pipeline (Updated) ". However, we are running into errors with the SIFT algorithm as follows “[ERROR] Error assigning memory for SIFT gradient vector”. There is more than enough memory available for the pipeline to be completed. Though the tractograms appeared fine, we’ve re-run the tractograms again but SIFT still failed. We also could not find anything on the help boards as it relates with this issue. How do we go about solving this issue? Any help is greatly appreciated.
