Hello CONN community, 

I am currently running my preprocessing step on CONN and kept meeting with this error.


Computing mask... : Failed 'Realign & Unwarp'
Matrix dimensions must agree.
In file "/space/-/-/spm/spm12/spm_uw_apply.m" (v6301), function "spm_uw_apply" at line 229.
In file "/space/-/-/packages/spm/spm12/config/spm_run_realignunwarp.m" (v6554), function "spm_run_realignunwarp"


I have about 100+ subjects and a very few of them have this issue. The preprocessing step would continue running for other participants, but it crashes before going on to the next preporcessing step. Some participants have less sessions than others, would this be the issue?


Can I please get some help on this?

Thank you.
