3dVol2Surf in SUMA

[Mlissa12]

Hello,

I'm sorry to disturb you, but I have a problem with SUMA.

Indeed, I am working on EEG fMRI of subjects with a cortical malformation and I would like to correlate my anatomical and functional data.

To do this I used Freesurfer as you explain in your blog, and I conducted with this software a group analysis comparing each of my sick subjects with 18 healthy subjects. I obtained a contrast in sig.mgh format on several parameters of interest (thickness, volume and gyration in particular). When I visualize my anatomical results on FreeSurfer, I get interesting surface maps. But I can't combine them with my functional data (GLM 1st level) from SPM which are in volumes and are not aligned to the template of fsaverage...

So I would like to use SUMA to transform my first level spm volume into a surface visible in Freesurfer and supperposable to sig.mgh contrasts. But I can't find the options of the command 3dVol2Surf which are adequate. Could you help me to find the options of this command that would be useful to me please?

Hi Melissa,

I apologize for the very late reply; I don't get automatic Github issues sent to my inbox, and I check them manually only once in a while.

Regarding your question, I think that the 3dVol2Surf command in this chapter should work, if you replace the midACC+tlrc file with your statistics file; it should work equally well with .nii files.

Best,
