How can I get the "HCP_visual_voxel.npz" for pre-training？

Hi

I'm reproducing this very interesting project. However, I don't know how to get the HCP dataset with the "HCP_visual_voxel.npz" to implement stageA1_mbm_pretrain.py. In fact, I was able to download the fMRI data in “nii.gz” format of the HCP 1200 dataset containing 1113 subjects. But I can't extract the ROI of the visual cortex from the nii file in 4-D and save it as HCP_visual_voxel.npz for each subject.

Can you provide more detailed implementation steps about HCP_visual_voxel.npz？

Thanks

Found a clue at https://mind-vis.github.io/supplementary.pdf. Perhaps the voxels are obtained by applying some sort of atlas?
