Hi Tino,
When I think 1D file, I think a single column of scalars, where the line
number implicitly means the node number. But when you say "with xyz
coordinates," I no longer think 1D file anymore. It's something else.
Are you sure AFNI wants to read data that way? You can probably use the
unix join command, followed by cut to pull off what I think you mean, i.e.:
x-coord y-coord z-coord z-score
But are you sure 3dSurfToVol wants the data this way?
I did have a look at the usage (it is actually 3dSurf2Vol -- not
3dSurfToVol, if anyone else wants a look), but it's 561 lines long. It
did appear to take a coord file, i.e.:
-surf_xyz_1D SXYZ_NODE_FILE : 1D coordinate file
e.g. -surf_xyz_1D my_surf_coords.1D
In Caret, you would use File: Save Data File: Coord file and save your
fiducial coord file as ASCII (or use caret_command -file-convert
-format-convert to do so). Then, use the unix/Linux cut command to chop
off the first column (node numbers). You could use tail to strip the
header.
Where in the usage does it suggest you want the four columns together in
a single file?
