Dear Freesurfer experts, <br>I am trying to prepare some NHP functional data for a whole brain group analysis, and I was wondering which sequence of steps you would recommend, given that the data cannot be processed with recon-all. <br>

I have surfaces from 4 subjects, but one subject for which I do not have an anatomy of sufficient quality and won&#39;t be able to obtain one. I would also like to align the data to the 112RM atlas by Mclaren et al. <br>
I was thinking that I could probably align the functional data per subject to the atlas, and then use this registration with func2sph-sess to align all subjects for the group analysis (again to the atlas). Does that make sense, given that I have only four out of five individual surfaces?<br>

<br>A second question is when to smooth the data. I assume that it makes most sense to smooth it after it has been transformed into surface space.  Would that be sphsmooth-<span class="il">sess</span>? <br><br>Finally, when doing the analysis, I would use isxavg-re-<span class="il">sess</span> or isxavg-fe-<span class="il">sess</span>, correct? <br>
<br>I am using Freesurfer v5.1.<br>Thank you very much for your advice, <br>Caspar<br><br><br>
