You still have to “smooth” even if you choose fwhm=0 to project the data in the fsaverage space.
So if I were you I would start with fwhm=5mm, check in the qdec console what is the final fwhm of your data (or check the fwhm.dat in the glmdir folder), and if you thinks it’s too high (I’d say >20mm), then go for fwhm=0mm, which should solve the problem. But the ideal if 5mm is too high is to smooth still a bit, by 1 or 2mm, if you are ok to go without qdec.

If I got right, I should either not smooth it after mri_preproc (no mri_surf2surf) or do it with kernels < 5mm, and that should make to FMHM fall below 30. Am I correct? Thanks, Pedro.

I’d say try first with 5mm, and check if this work, if it doesn't decrease to 0mm. And if you want then to work around, you can tune your smoothing with values in between to achieve a smoothness level of 15mm, most often with 1 or 2mm, but qdec won’t accept it so you’ll have to go for the commandline stats.
