You don't need a .w. I'm encouraging people to stop using .w.

[EMAIL PROTECTED] wrote:Hi, I would like to paint group analysis results to the surface of the fsaverage brain to produce .w files. With individual subject analyses (that were calculated in individual space, i.e. not morphed), I have been able to use mri_vol2surf in this manner: mri_vol2surf --src V-REST/sig --src_type bfloat -srcreg ../register.dat --hemi lh --o ./V-REST-lh.w --out_type paint In the group analysis, the individual subjects' volumes were morphed into sperical space where the spatial alignment across subjects was done. I used the average brain "fsaverage" as the target brain. Here the above mri_vol2surf will not work. I am unsure how to do the corresponding paint job for the morphed group analysis data. Would the following command do what needs to be done? mri_surf2surf --srcsubject fsaverage --trgsubject fsaverage --srcsurfval V-REST/sig-lh --src_type bfloat --hemi lh --trgsurfval ./V-REST-lh.w --trg_type paint Thanks, Tommi --- Tommi Raij, M.D., Ph.D. MGH/MIT/HMS Athinoula A.
