Hey Sylvian,

I'm glad you're finding CPAC useful!

You're absolutely right that the creation of this kind of matrix is necessary when generating certain derivatives (Centrality, CWAS). An early version of CPAC had the option to export this matrix, but in practice the memory needed to do so was excessive, so the feature was removed. At various times we have discussed adding this option back, but have so far been focusing on other features. If this is something you'd like to see in a future release, please feel free to create a new issue on our development site at https://github.com/FCP-INDI/C-PAC/issues and we can discuss it with the development team.

Thanks for using CPAC, and let us know if you have any other questions.

Dan Lurie
