Hello FreeSurfer Developers,

I'm trying to pre-process some diffusion data based on the tutorial: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/DiffusionV6.0

I am getting the following warning followed by the program hanging

-------------------------- Creating output directory /home1/am2359/fs6_data/fpeb_app_fs/fpeb001/dtrecon Loading y from /home1/am2359/fs6_data/fpeb_app_fs/fpeb001/dtrecon/dwi-ec.nii.gz ... done reading. MatrixReadTxT: could not scan value [1][1]

I would greatly appreciate your assistance.
