Hi Jian, I’d suggest that you’ve encountered [the same problem as Manuel](https://community.mrtrix.org/t/error-response-function/393): The drive hosting the script temporary directory contents is running out of space. Unfortunately it’s not actually giving a useful error to inform you of such. You can use the `-tempdir` option when calling the script to manually specify the location of the temporary directory. It looks like the subsequent errors are arising because you have copy&pasted lines from the terminal output of the script; e.g. from this exerpt: ```bash jian.chen@MCRI.EDU.AU@mcri-n0186:/isilon/data/jianc/ALL/mrtrix/FBA$ Command: mrtransform /isilon/data/jianc/ALL/mrtrix/FBA/upsampled_dwi_mask/C_ALL_065.mif -linear linear_transforms_initial/C_ALL_065.txt -datatype float32 masks_transformed/C_ALL_065_translated.mif Command:: command not found ``` , the system sees the following as the instruction that you are trying to execute: ```bash Command: mrtransform /isilon/data/jianc/ALL/mrtrix/FBA/upsampled_dwi_mask/C_ALL_065.mif -linear linear_transforms_initial/C_ALL_065.txt -datatype float32 masks_transformed/C_ALL_065_translated.mif ``` It’s therefore looking for a program on your system called “`Command:`”, and can’t find it.
