Have anyone checked the content in rest_spm_slice_vol?

Hi everyone, When I regressed out covariates in DPARSFA (version 2.3), I encounter the following errors: Resample Masks (/databank/Ketamine/DPARSF_V2.3_130615/Templates/BrainMask_05_91x109x91.img) to the resolution of functional images. Resample Masks (/databank/Ketamine/DPARSF_V2.3_130615/Templates/CsfMask_07_91x109x91.img) to the resolution of functional images.

Error using ==> rest_spm_slice_vol File too small. I checked the content of this matlab function and found it's quite strange in my computer. So any ideas on this? The content of spm_read_vols is the same as rest_spm_read_vols, which is listed as followings. function varargout = spm_slice_vol(varargin) % returns a slice through a memory mapped image - a compiled routine % FORMAT X = spm_slice_vol(V,A,dim,hold); % V - is a memory mapped image volume % A - is a 4 x 4 transformation matrix % dim - [i j] defines the two dimensions of the output image.
