good name there!
Unfortunately I fear the documentation is scarce and we currently lack the resources to improve them.
I guess you already checked the manual? Then the walkthrough-video on the website is probably the best asset.
After you’ve been through that, I’d advise to join our slack channel and ask specific questions there.
Best to clarify what’s the state of your analysis (e.g. electrodes reconstructed, VTAs calculated?) and more importantly what exactly you wish to do. Running connectomics is a bit unspecific, I assume you first want to create connectivity maps from your VTAs? But if so, what’s the next step? I.e. is there a behavioral or clinical parameter that you want to address by means of connectivity to the VTA?
Would definitely need to have a pretty precise plan of what you want to answer to really help. Reason is that there are basically 4 regions in lead dbs where one can do one or the other (running seeds or connectivity matrices -> lead mapper; visualizing and analyzing single patient connectivity -> “convis” module directly in the lead dbs 3D viewer; running parcellation based connectivity stats from your vtas -> lead group; analyzing patient specific connectivity data -> lead connectome; group-wise analysis of such -> lead group connectome). I assume the latter two do not count here since you lack patient DTI. But just wanted to make the point that there are various tools for running connectomics in the lead suite..
Hope this helps!
