How to show the 3d image of brain for seeg data?

I have sEEG data, organized in BIDS format. It includes the file with MNI coordinates for channels, along with other data. I want to create an image of brain as given in tutorial:
https://mne.tools/stable/auto_tutorials/clinical/20_seeg.html

I am unable to understand the “subjects_dir” in my data. I can understand that it is a path to subjects directory. My dataset was a zipped file for each subject. Is there any other way to get a 3d image of brain with channels ?

Thanks

The subject dir is a directory of FreeSurfer reconstruction. You can follow this tutorial Locating intracranial electrode contacts — MNE 1.0.0 documentation.
Well, as you want to use MNI coordinates, I presume that you want to label the contacts with some templates in MNI space, like AAL. If you just want to plot the electrodes with MNI coordinates, setting the subject as fsaverage and subject_dir as the default value in the tutorial is enough for fsaverage is in MNI coordinates.
