Hi HCP team,
Thanks a lot for your dedication to science.
I am using your HCP-S900 dataset and Connectome Workbench for research.
Specifically, in order to compare the E/MEG inverse solution, we are expecting
to get the low resolution resting state fMRI on native space surface.
We are trying to use HCP-S900 dataset for a test.
For example, we want to downsample the
105923\MNINonLinear\Result\rfMRI_REST1_LR\rfMRI_REST1_LR_Atlas_hp2000_clean.dtseries.nii.
First, I use the wb_coomand -surface-resample in matlab to downsample the
anatomical data(
system([wb_command, ' -surface-resample ',' ',file.highResSurface{hemi},'
',file.highResSphere{hemi},' ',file.lowResSphere{hemi},' ', res_method,'
',file.lowResSurface{hemi}]);) for getting a low resolution suface which
expecting to be around 3k vertices for each hemisphere. PS: downsampling the
surface and projecting back to native space is for calculating the E/MEG
leadfied.
Then I am trying to use the wb_coomand -cifti-resample for downsample the
functional data(
system([wb_command, ' -cifti-resample ',' ',file.highResCii,'
',res_src_direction,' ',cifti_templete,' ',res_template_direction,'
',res_surface_method,' ', res_volume_method,' ',file.lowResCii]);) .
Question:
1. I don't know what should I put in the <cifti_templete> for wb_coomand
-cifti-resample?
2. Can I use the same project matrix from
\105923\MNINonLinear\fsaverage_LR32k\105923.R.{pial or
white}.32k_fs_LR.surf.gii file, which is 4*4 matrix, for projecting
low-resolution 3k_fs_LR back, the output of -surface-resample, to individual
native space?
Thank you!
Best,
Rigel
