I'm not sure what the cause of this problem is. If the dimensions are
512*512*320, then the size of the file seems to be correct (for a floating
point image, requireing 4 bytes per voxel). Is it possible that you may have
tried to display the bias corrected image before SPM had finished writing it?
Best regards,
