Note that you should not include all the group members on the stxgrinder-sess command-line, only the name of the group as if it were an individual.

• Repeat stxgrinder-sess for all contrasts.

• Assign the name of the group analysis with the <group> parameter. If the analysis is in TalairachSpace then <space> = tal. If the analysis is in SphericalSpace, then <space> = sph, and -spacedir must be specified from FsFastSphericalSmooth (sphsmooth-sess).
