External Email - Use Caution Dear experts,
I posted a message last week about converting NIFTI files into GIFTI format, then GIFTI to CIFTI, whilst keeping these functional data in the same space as the subjects FS surface. I got some information RE usign the HCP workbench, but I wondered if running mri_vol2surf could achieve the same thing as running the wb_command? For example, is it advisable to run the following command for each hemisphere and then merge them into a single GIFTI/CIFTI in the next steps? * mri_vol2surf --src filtered_func_data.nii.gz --out movie_surface.gii --srcreg partial-to-struct.lta --hemi lh --projfrac 0.5 --out_type gii I have also tried the wb_command option but this has been unsuccesful: I first ran the mris_convert to convert the relevant surf files into .gii format (from FS format) * e.g. mris_convert lh.pial lh.pial.surf.gii I then applied the transformation to align the filtered_func to the T1 * mri_vol2vol --mov filtered_func_data.nii.gz --reg partial-to-struct.lta --fstarg --o movie_t1_space.nii.gz I then tried to run the following wb command * wb_command -volume-to-surface-mapping /home/masontwells/Documents/Data/MovPPT_001/MovPPT_001.feat/movie_t1_space.nii.gz /home/masontwells/Documents/Data/freesurfer/subjects/MovPPT_001/surf/lh.inflated.surf.gii /home/masontwells/Documents/Data/MovPPT_001/lh_movie.gii -ribbon-constrained /home/masontwells/Documents/Data/freesurfer/subjects/MovPPT_001/surf/lh.white.surf.gii /home/masontwells/Documents/Data/freesurfer/subjects/MovPPT_001/surf/lh.pial.surf.gii Which resulted in this subsequent error. ERROR: NAME OF FILE: movie_t1_space.nii.gz PATH TO FILE: /home/masontwells/Documents/Data/MovPPT_001/MovPPT_001.feat Unable to allocate memory for reading the file. File Size: 3.24 Gigabytes Note: The amount of memory required to read a data file may be substantially larger than the size of the file due to the way the file's data is organized in memory or compression of data within the file. Any advice on how to convert NIFTI to GIFTI and then GIFTI to CIFTI whilst keeping the data in the subjects space would be really appreciated.
