DPRSFA error messages

Hi all,

I am using DPSRSFA toolbox for my Resting state data. Also, I am planning to preprocess all my data and use compcorr using subject's own T1 structural images as well.
Thing I am doing is Slice time correction, Realignement, Reorient fun, Reorient T1* T1 Coreg to Fun, New Segment+DARTEL, Nuisance Covariates with (Rigid-body 6, White matter, CSF), Normalization, Smooth, ALFF+fALFF and ReHo.
I believe toolbox ran upto Realignment but crashed after with following error messages
