Can I re-do the preprocessing for OpenNeuro ds000243 using existing parameters?

The [SPM analysis] of OpenNeuro dataset ds00243 has fMRI and T1 images that have been mapped to MNI space using SPM. There are also tissue class segmentations (c1 = GM, c2 = WM, etc) of the T1 image in native space, and files *seg8.mat and y*.nii for each subject.

I would like to use these images for an analysis that needs the c1 images in standard space, and preferably with the original warpings to standard space (i.e. without re-computing the *seg8.mat and y*.nii files). Is that possible with the OpenNeuro tools or in SPM8(or 12)?

Many thanks!
