-spec-file-change-resolution will not get you to the fs_LR 32k atlas from fs_LR
164k (but it may get you deceptively close, making it even more treacherous).
Those messages aren't errors, and the reasons behind them are better left
alone, as this isn't the command you want.
What you need to do is to use the fs_LR atlas files for resampling the surface.
In caret5, this requires deformation map files, which we have probably already
made for going between fs_LR 32k and 164k (Donna, do you know if these are
available?), with the -deformation-map-apply command. However, we now do this
in Connectome Workbench using atlas spheres directly with the -surface-resample
command (the fs_LR 32k and 164k spheres are aligned by definition, but going to
or from other atlases will need a cross-atlas registered sphere).

Subject: Re: [caret-users] projecting functional MRI to gii surfaces
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
[-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.

Re: [caret-users] projecting functional MRI to gii surfaces
Yes，I have a lot of volumes which need be projected to surface. I only know how
to use the 'map volume to surface '. I don't know how to use the command. Could
you give me an example?
Can the file of *.coord.gii be thought as the file? But
I only found .coord file can be used in the menu of "caret command executor" .
How about "topo"?
another thing is how to set the ?

You may need to do the -file-convert -format-convert XML_BASE64_GZIP (not ASCII) on the metric file (and maybe even rename it to end in .func.gii) to load it in matlab as a gifti file. The metric file does not contain voxel values, it contains a value at each surface vertex. The correspondence between voxels and surface vertices is purely spatial, and unless you used enclosing voxel mapping (which is not good for continuous data values like functional activation), each vertex contains an interpolated value derived from several voxels.

Re: [caret-users] projecting functional MRI to gii surfaces
I am sorry that I still don't know how to do it. Firstly, regularly spaced Cartesian grids were generated on the flattened PALS-B12 average surface of the left and right hemispheres using the Caret software. Grid points were spaced 20 mm apart on the flattened surface. Then, How to get the 3-dimensional (3D) stereotactic coordinates? Need I save this grid as a file and read this file? But how to save it? the coordinates I can get is the MNI coordinates?

Re: [caret-users] projecting functional MRI to gii surfaces
Thank you for your help. Now, I meet another problem. I project all functional MRI to 164k fs_LR surface. Every subject have 135 volumes. I want get fMRI time course for surface vertices of every subject. How should I do?

We have seen cases before where the file was just a header -- no data. Inexplicably, the presence of a non-english character set on the system used has caused this sort of trouble. If there is a system nearby that does not have a non-english character set installed, you might see if Caret works there. Or remove any non-english character sets on your system and see if it helps.

[caret-users] projecting functional MRI to gii surfaces
Dear all, I used the Freesurfer_to_fs_LR Pipeline to get 164k fs_LR surface. Now I want to map functional volumes to surfaces. In volume selection page, I choose my file 'ff001_010.nii'; In spec file and surface selection page, I choose the file 'study1.L.orig.164k_fs_LR'. I get a file 'map_data_0_31_Jul_2014_15_10_13.metric'. But I find I couldn't open this file. Which step is wrong? How can you do it? ___ caret-users mailing list caret-users@brainvis.wustl.edu http://brainvis.wustl.edu/mailman/listinfo/caret-users
