Excellent suggestions. In the spirit of the NITRC projects, let's annotate how to get at these various tools you mention:

PLSGUI - hmmm, not in NITRC! It should be! But no worries, it's at http://www.rotman-baycrest.on.ca/index.p...

BrainVoyager - also not in NITRC, darn. I keep asking them, but to no avail as yet. If anyone else can try to suggest their adding a project, feel free. Still no worries, it's at http://www.brainvoyager.com/

SPM - ah yes, here we go: http://www.nitrc.org/projects/spm/

MarsBar - alas, not at NITRC, but I've pinged them on occasion, so if anyone has any influence there, feel free to exert it. https://sourceforge.net/projects/marsbar... Since it's SourceForge, it'll be easy to include in NITRC!

AFNI - yeah! http://www.nitrc.org/projects/afni/
