External Email - Use Caution
Dear,
I'm attempting to increase the resolution of an image but I get the
following error when I run the mri_convert command:
Command:
*mri_convert -rt nearest -it nii -i XX.nii.gz -ds 0.2 0.2 0.2 -ot nii -o
XX_sr_temp.nii.gz*
Log:

Error:

I was not able to find any similar error on the mailing list. Does anyone
have any thoughts on how to trouble-shoot this one?
More info:
1) FreeSurfer version:*
freesurfer-linux-ubuntu22_x86_64-8.0.0-20250204-0f2bd3a*
2) Platform:
Distributor ID: Ubuntu
Description: *Ubuntu 22.04.5 LTS*
Release: 22.04
Codename: jammy
3) uname -a: *Linux eec78b7407cc 6.8.0-60-generic #63~22.04.1-Ubuntu SMP
PREEMPT_DYNAMIC Tue Apr 22 19:00:15 UTC 2 x86_64 x86_64 x86_64 GNU/Linu*
Note1: I also tried with FreeSurfer 7.4.1, and the command, with the same
input data, works in that version. Nevertheless, I wanted to update to
8.0.0.
Note2: The same command does work on 8.0.0 when* -ds >1*
Thanks in advance.
