Hi Robin,
We can certainly help get you going, especially since you are here at NIH. It would be best if you can bring a laptop with AFNI installed already. I'll contact you by email to set the time. Should you be heading back to Europe, there will be a weeklong bootcamp in Tubigen starting on April 13th, the class is full but you can always try and contact Xin Yu to see if you can sit through the lectures.
cheers,
Ziad
