Hello,

I am planning to perform an ROI analysis, and want to project the volumetric data to the surface for better viewing. It seems like AFNI's 3dVol2Surf is what I need to use, but this is my first time using the command, so I wanted to make sure that I am using it properly. I used @SUMA_Make_Spec_FS beforehand to create a SUMA directory with the SUMA-specific files. Then I use 3dVol2Surf, with the following options:

3dVol2Surf \
-spec $freesurfer_dir/SUMA/std.141.${subj}_both.spec \
-surf_A $freesurfer_dir/SUMA/std.141.lh.smoothwm.asc \
-surf_B $freesurfer_dir/SUMA/std.141.lh.pial.asc \
-sv $data_dir/T1w.nii.gz \
-grid_parent $data_dir/run-01.func.nii.gz \
-map_func ave \
out_1D $freesurfer_dir/SUMA/test.1D \
out_niml $freesurfer_dir/SUMA/test.niml.dset

The file for the -sv option is my anatomical (in MNI space), and the file for the -grid_parent option is the first run of my functional data (also in MNI space).

When I tried running the command, I received this error: ** surface name '/N/dc2/scratch/dlevitas/fMRI_data/std/001/freesurfer/sub-001/SUMA/std.141.lh.smoothwm.asc' not found

I double checked, the file is indeed there; however, I tried changing to -surf_A smoothwm, but then got this error: ** surf name 6, 'smoothwm': multiple matches
'/N/dc2/scratch/dlevitas/fMRI_data/std/001/freesurfer/sub-001/SUMA/././std.141.rh.smoothwm.asc' and '/N/dc2/scratch/dlevitas/fMRI_data/std/001/freesurfer/sub-001/SUMA/././std.141.lh.smoothwm.asc'

I'm unsure why the error message is occurring the first time, and wanted to see if there are options for resolving it.

Thank you.

Dan
