Hello. I have problem in opening the multi-volume nii file. I downloaded the pre-processed resting state fMRI data (10 unrelated subjects), checked the integrity of the files, and unzipped them according the instruction in the Q3_Release_Reference _Manual. However, the problem is, when I tried to load the rfMRI_REST1_LR(or RL).nii into MATLAB workspace using the function 'spm_read_vols' in SPM8, it always failed. And I found that MATLAB can actually access the first 10 volumes of the .nii file, but failed to read the rest of it. This problem appeared in ALL of the 10 unrelated subjects' rfMRI_REST1_preproc data. I believe that this problem is caused by the .nii file itself for the additional reasons below: 1) I tried to convert the 4D nii into 1200 3D niis by using the 'dcm2nii' tool in the MRICRON package, and it can only convert the first 10 volumes, 2) I viewed the LAST 10 volumes of the nii file using MRICRON, and very interestingly, the brain was misplaced in the last 10 volumes, 3) this problem appeared in different platforms(windows, linux, 32-bit, and 64-bit). All files are unlikely to be corrupted during the downloading process, because I have checked the hash of the files. So, I am quite puzzled with this problem. Please offer some advise. Thank you for your time!
