Wrong ROI definition when extracting CSF/WM signal etc

Hello, I am receiving a bug when extracting the ROI signals (i.e white matter, CSF) for the nuisance covariates regression. The error appears after slice timing, realignment have been done. The error I received is below, I believe it is due to DPARSFA not being able to find the masks in the working directory. The error only appears with DPARSFA. My data was converted from DICOM --> NIFTI outside of DPARSF, then converted into spm format using freesurfers mri_convert to 208 indiviudal img files. The original raw data are as follows: Voxels: 128 x 128 x 29 Dimensions: 1.875 x 1.875 x 4.5mm.     ----------------------------------------------------------------------------------------------------------------------------                                                                                                      Generating voxel specific head motion for /home/alistair/Documents/dparsftest/RealignParameter/3994A/rp_aimg001.txt finished.
