Hi all,
I have results of a subject-specific connectivity analysis on a) volumetric
(.nii.gz) and b) CIFTI grayordinates (.dtseries.nii) data for a subset of 3T
rfMRI HCP1200 subjects. In order to check the spatial correspondence, I am
trying to map the former onto the space of the latter.
To do so, I used the following steps using wb command line:
1- Mapped the volumetric data to subject-specific surface using
-volume-to-surface-mapping:
wb_command -volume-to-surface-mapping $input_nii $subject_gifti_left
$output_gifti_left -trilinear
wb_command -volume-to-surface-mapping $input_nii
$subject_gifti_right $output_gifti_right -trilinear
2- Combined these mapped cortical responses and subcortical grey matter voxel
responses in one CIFTI file using -cifti-create-dense-from-template:
wb_command -cifti-create-dense-from-template $template_cifti
$output_cifti -series 1 0 -volume-all $input_nii -metric CORTEX_LEFT $
output_gifti_left -metric CORTEX_RIGHT $output_gifti_right
where $template_cifti is a group average of the aforementioned analysis on
CIFTI data.
I was wondering if this way of mapping is correct? I would very much appreciate
your feedback...
So many thanks,
Rezvan
