Hi Graham,

Before answering any of your questions, let me just note
that these surface programs are still very much "work in
progress". That also applies to file formats, program
interactions, and documentation. Ziad and I are coughing
up enhancements regularly, so you may have to be patient
when looking for something. Anyway, I just wanted to
give you a feel for where we're at. On to the questions:

1. I believe the only ways for suma to get at functional
data is from afni or from a color map file (probably
via 3dVol2Surf). Oh yes, Ziad also has output going
directly from SurfSmooth to suma right now.

2. You will have to produce your own color map, based on
the data output by 3dVol2Surf. Consider using the
program MakeColorMap.

3a. You cannot. The 3dVol2Surf functionality has not yet
made it into suma or afni, that is a future goal. At
this point, you will have to use 3dVol2Surf on the
command line, and go from there (either making a color
map, or using 3dSurf2Vol to map the results to an AFNI
dataset). Note that 3dSurf2Vol has some good options
to go to an AFNI dataset.

3b. There again you will will have to make your own color
map from the pial surface results. Or make an AFNI
dataset. Of course the color map can be applied to any
surface.

3c. Use the 'midpoint' mapping function in 3dVol2Surf, and
proceed to make a color map.

Eventually Ziad and I will make these steps easier... :)
