fMRIb v 1.21 error: cannot match the size of A to the iterator when it's using pcorr2 function

[DBermudez0]

Hi,

I am currently using fMRIb v 1.21 with EEGLAB v2020.0 and MATLAB 2021a. I am attempting to remove the gradient artifact, however, when I run fastranc it terminates the process at stage 1 of 2 (slice alignment) with the following error: cannot match the size of A to the iterator when it's using pcorr2 function. What does this error mean? and How do I fix it?

Thank you,
Dalton
