Hi,
I loaded my structural and functional data in CONN (MPR T1, 2 tasks and resting state fMRI) that were previously converted in NIFTII with DCM2niix.
I have the following error message during the pre-processing:

SPM12: spm_uw_apply (v6301)                        18:44:20 - 06/05/2019
========================================================================
Computing mask...                       :                               06-May-2019 18:44:23 - Failed  'Realign & Unwarp'
Matrix dimensions must agree.

In file "C:\Users\TORDJM01\Downloads\spm12\config\spm_run_realignunwarp.m" (v6554), function "spm_run_realignunwarp" at line 98.

The following modules did not run:
Failed: Realign & Unwarp

Could you help me with that please?
Thank you very much!!!
