What kind of analysis do you have in mind? There is a new ³native² matlab CIFTI reader/writer written by Robert Oostenveld that you could give a try: https://github.com/oostenveld/cifti, which I think reads in the header info.
If you have issues, you¹ll need to ask him about them, as I¹ve not yet extensively used his software. Peace, Matt.
