[FieldTrip] Missing dataset for OPM phantom tutorial

[Naidile S - 240900566 - MITMPL]

Dear FieldTrip community,
I am trying to follow the tutorial “Using a MEG phantom for validation and OPM calibration”:
https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.fieldtriptoolbox.org%2Ftutorial%2Fsource%2Fopm_phantom%2F&data=05%7C02%7Cfieldtrip%40science.ru.nl%7Ca9aa6a8f048a43ab20ad08df0e470e85%7C084578d9400d4a5aa7c7e76ca47af400%7C1%7C0%7C639245370961302885%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C40000%7C%7C%7C&sdata=OWbCmL3yGqIioXaIuAPmVJlp4EzxO4ys2kTR2RS3IrQ%3D&reserved=0
The tutorial refers to the following CTF dataset:
phantom_3031000.01_20260721_01.ds
It also requires:
cad_mesh.mat
However, the corresponding directory on the FieldTrip download server appears to be empty:
https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdownload.fieldtriptoolbox.org%2Ftutorial%2Fopm_phantom%2F&data=05%7C02%7Cfieldtrip%40science.ru.nl%7Ca9aa6a8f048a43ab20ad08df0e470e85%7C084578d9400d4a5aa7c7e76ca47af400%7C1%7C0%7C639245370961325130%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C40000%7C%7C%7C&sdata=cJldMZJRwDBiYtjftICzLUb9gIVA6NydXdVdEgMyywg%3D&reserved=0
Could you please let me know where I can download the CTF phantom dataset and cad_mesh.mat? If available, I would also appreciate information about downloading the FieldLine OPM recording used in the tutorial.
Thank you for your help.
Kind regards,
Naidile S
