Hi Naveed,
So what are the 3dANOVA2 files that get written out? Do they end with .niml.dset?
Viewing them should be straight forward.
1- Open suma with one set of standard meshes that matches the one you used for the analysis
2- Select one hemisphere (right-click), open the surface controller (view --> Surface Controller, or ctrl+s) then click on "Load Dset" and pick the dataset in question. After you do so you can colorize the data as you would in AFNI.
If all of this is new to you, then you probably want to go through the
suma.pdf slides. You can also download the
class material these slides refer to.
cheers,
Ziad
