Dear MRtrix3 community, In following situation what should I do?

    • open file first-L_Caud_first.vtk to save.
    • succesfully opened file first-L_Caud_first.vtk to save.

System is Windows 11, Ubuntu 22.04 (WSL)

Edit = In a priot dataset 5ttgen worked fine in my setup, but for this specific data it does not work. And also same data and same 5ttgen function worked on another device with Mac setup which belongs to my fellow.

I dont understand why when setup and dataset changed function gave error.

This is what I got after run_first_all command, I dont understand what is the problem

These are some other log files of first.logs

What should I do in this situation. Images are not that large (100mb for T1.nii.gz), and my UbuntuWSL has 8gb of RAM.
