I think that would be ok, but I would run this instead
mri_surf2surf --hemi lh --srcsubject 1001 --srcsurfval thickness --src_type
curv --cortex --trgsubject fsaverage5 --trgsurfval ./mgh/1001_lh_fs5_thick.mgh
--trg_type mgh –fwhm-trg 10

Dear Freesurfer experts,
The mri_surf2surf example 1 specifies that lh thickness is resampled onto the
7th order icosahedron. Does it place the lh.thickness curv into freesurfer
space, or is it still in the subject's native space (i.e., pre-transformation
to the fsaverage template)?
I used a similar process to downsample subjects' thickness to fs5 resolution,
which I then concatenated and used as input for PALM. What I'm now wondering is
whether results may be due to misalignment between individual subjects because
they were not transformed to the fsaverage template and space. Do the inputs
below (-srcsurfval) need to be thickness.fsaverage.mgh (already mris_preproc'd
in the recon-all pipeline) instead?
mri_surf2surf --hemi lh --srcsubject 1001 --srcsurfval thickness --src_type
curv --cortex --trgsubject ico --trgicoorder 5 --trgsurfval
./mgh/1001_lh_fs5_thick.mgh --trg_type mgh –fwhm-trg 10
**Note: My apologies if this re-posts, but it doesn't seem like my initial
submission went through**
With gratitude,
Dan
