I'm working on children/adolescents (7-15 yo) high-density EEG data (EGI 256), but I do not have individual MRI scans, therefore I am using the templates by John Richards (https://www.nitrc.org/frs/?group_id=1361, one different template every 6 months) as "individual MRI surrogates".
I tried a segmentation via CAT12 as it is fully interfaced with brainstorm. Is there an easy way to point to the TPM_11.5 template I found in the cat12 template_volumes folder?
Should I also change the standard template for group analysis? If yes, do you have any suggestion regarding where to find a proper template ?

What do you mean by "point to"?

If the CAT12 segmentation works correctly on all the age-matched templates for each subject, you don't need to change the anatomy template in the folder "Default anatomy".
What matters is that sources are estimated on a "realistic" template (head size that matches the age range) for each subject, then it doesn't matter much on which template you project all the individual results for group analysis, since they are all co-registered using the same procedure (FreeSurfer/CAT12 registered spheres)
By "point to", I mean that I guess by default Brainstorm uses the classic TPM (for adults).
question 1: where is the TPM used by Brainstom located?
I found one in the .brainstorm folder, one in the spm folder and one in the cat12 folder, I am not sure whether Brainstom imports its one from cat12/spm or not.
I can replace the adult TPM with the children TPM in the proper folder (see question 1), but I am wandering: is there a smarter way to say: "Hey, Brainstom, please, pick the children TPM instead of the adult TPM?"
@CGaser Do you think we should add an option to let users select a custom TPM.nii file in the CAT12 process options? (And if not specified, it would use the one in the .brainstorm folder)
