I'm not clear on what you mean by "I want get fMRI time course for surface
vertices of every subject."
If you just mean how do you scale up -- map that many volumes to all your
subjects -- then I recommend scripting it and using caret_command. (Note that
Workbench, the software that is superseding Caret 5.*, has more robust mapping
features than caret_command, but I am going to provide the caret_command usage,
since this is the caret-users list. There is also a hcp-users list that covers
workbench.)
Here is the usage for the command that maps volumes onto surfaces:
caret_command -volume-map-to-surface
<coordinate-file-name>
<topology-file-name>
<input-metric-or-paint-file-name>
<output-metric-or-paint-file-name>
<algorithm>
<input-volume-file-names>
[-av average-voxel-neighbor-cube-size (mm)]
[-bf brain-fish-max-distance
brain-fish-splat factor]
[-g gaussian-neighbor-cube-size (mm)
sigma-norm
sigma-tang
norm below cutoff (mm)
norm above cutoff (mm)
tang-cutoff (mm)]
[-mv maximum-voxel-neighbor-cube-size (mm)]
[-sv strongest-voxel-neighbor-cube-size (mm)]
Map volume(s) to a surface metric or paint file.
For successful mapping, both the surface and the volume
must be in the same stereotaxic space.
"algorithm" is one of:
METRIC_AVERAGE_NODES
METRIC_AVERAGE_VOXEL
METRIC_ENCLOSING_VOXEL
METRIC_GAUSSIAN
METRIC_INTERPOLATED_VOXEL
METRIC_MAXIMUM_VOXEL
METRIC_MCW_BRAIN_FISH
METRIC_STRONGEST_VOXEL
PAINT_ENCLOSING_VOXEL
If the input metric or paint file name is not an empty string
(""), the newly create metric or paint columns will be
appended to the file and then written with the output file
name.
