Hi Michael, I’m happy to hear you are making good progress with CIFTI and Connectome Workbench. You can indeed use the PALM software to do statistical inference on CIFTI data, and that is the tool we recommend. Peace,
Matt.

Our neuroradiology laboratory at the University of Colorado is beginning to use it. It has already proved to be extremely helpful in aiding the interpretation of existing resting state results. My question is: does the HCP Connectome Workbench provide an internal mechanism for the generation of statistical comparisons / contrasts within or between CIFTI files? I am exploring the dense resting state connectivity data. My goal is to construct a contrast map for statistical inference. I would like to compare whole brain (surface "voxels" + subcortical / cerebellar voxels) connectivity between two explicitly defined voxels within the dense resting state connectivity CIFTI file (or construct new whole-brain connectivity map CIFTI files for two explicitly defined voxels, and statistically compare these two maps). So, the desired resultant map / CIFTI file would illustrate the statistically significant difference in connectivity between these two points across the whole brain. Is there a way to do this with “-cifti-math” or the correlation command? As a corollary, can this be performed in FSL / PALM? This is probably a very basic question, but coming from years of SPM8 / SPM12 experience it is not very intuitive… Any comments, suggestions, or pointers would be much appreciated!
