Error report in the GRF correction of M_Interaction_F.nii

Dear teachers,

I performed mixed effect analysis in DPABI for my data (higher subgroup vs. lower subgroup )*two conditions (A pic  vs. B pic). And  I found that there is error report when I apply GRF correction for M_Interaction_F.nii created in the analysis as shown in the picture below. How to deal with it? Thank you!
