Hi, Is it possible to run recon-all so that both control point edits and brain volumes can be processed with a single command? Currently I use recon-all -autorecon2-cp -autorecon3 -subjid for corrections to control points and recon-all -autorecon2-pial -autorecon3 -subjid for corrections to

Before viewing it on the surface, you should view it in the volume with tkmedit. You can also load the surfaces in the volume (they show up as lines), and see if the surfaces intersect the activatino. Also, please remember to provide us with all the relevant info. See surfer.nmr.mgh.harvard.

Dear Glen, there is something you have to take into account when using FDR separately at various regions of a parcelled brain. It do not control de Global FDR if the null hypothesis is true in many of these regions. Although FDR provides strong control of false positives under the null hypothe

Dear Manja, It is statistically valid for the threshold suggested by FDR to vary in the different hemispheres. The reason is that FDR defines a proportion, not an absolute. The FDR procedure suggests a p-value threshold with the property that of all positive results at that threshold, one can expe
