Question about surface plot: where is the "surf_mesh" file in the fmriprep output directory?

1

Hi, I’ve been engaging fMRI analyses, but new to analyse surface data.

Now, I’ve done fmriprep like this:
fmriprep-docker dir1 dir2 participant --participant-label sub --fs-license-file fsllocation --output-spaces MNI152NLin6Asym T1w fsnative func

Then, I did the decoding/encoding analyses in the individual space (not normalized MNI152 space because it’s more conventional).

My question is, when I use nilearn’s function “surface.vol_to_surf”, which file I should use for surf_mesh? I believe (hope) it is in the output directory of the fmriprep, but I don’t have any idea mainly because I don’t fully understand freesurfer…
https://nilearn.github.io/auto_examples/04_glm_first_level/plot_localizer_surface_analysis.html

I’d really appreciate it if you could tell me some information!

Sincerely,
