To get a dconn loaded in matlab, you of course need to have a large amount of available memory. Freezing is what I would expect if you don't have enough memory, and start using a lot of swap space (some ways of loading might initially load it as double precision, and need twice the memory).
As you mention specifically c++ as your end goal, have a look at CiftiLib, as it is a c++ library for reading and writing cifti files, and has better support and features than currently available matlab cifti reading/writing (for instance, on disk reading/writing (not reading the entire file into memory first), easy construction and full support of dimension mappings of all supported types): https://github.com/Washington-University/CiftiLib Tim On Mon, Nov 23, 2015 at 11:18 AM, David Dalmazzo <davm...@gmail.com> wrote: > Hello, > I work in Specs Lab in Pompeu Fabra University as a Phd student. > I'm building an app for connectome visualisation and brain activity > simulation called BrainX3.
