Supporting “arbitrary” formats requires putting a whole system in place for describing the format, and making it queryable. The good thing is that if the pconn’s are available, users could use those inputs to their own derived graph-theoretic measures.

Most of the files are NxN connectivity matrices, where N could denote, for instance, ROIs from different parcellation schemes or resting-state functional networks. Ok, so one option is to transform these matrices into cifti files and share them through BALSA. On the one hand, this is a nice solution for it solves the user term uses. On the other, it is a bit of a roundabout way to store these files in the context of my manuscript. The matrices are used to derive graph-theoretic measures about brain organization (rather than for visualization purposes), so researchers interested in that would need to convert the cifti files back to CSV. More generally, do you suggest any methods to share HCP-derived files in an arbitrary format? Thanks in advance for the help.

See wb_command -cifti-parcellate (to make a template parcellated cifti file you can use to import data into), -cifti-label-import (to get your network ROIs into the format -cifti-parcellate wants), and -cifti-convert (and its -from-text option, to read csv or other text data and output cifti).

I used the connectomes to computed graph-theoretic measures that are part of a manuscript I am working on. My question concerns the sharing of these connectomes and graph-theoretic measures. My current understanding is that sharing this data is ok as long as I make sure users abide to the HCP data usage terms. What are your suggestions on how to do this? I've seen BALSA proposed to this end, since it provides a built-in mechanism of user terms, but my files are CSV or .mat files rather than WB scenes. Thanks in advance for your help.
