Awesome, thanks for the suggestions. I'll try that. And yes, I agree I
would love to be able to launch Chimera from inside Cytoscape, but it
wasn't working. Believe me I tried. On both linux and windows.
Entering the path doesn't work, either to the directory OR the
executable, adding structureViz.chimeraPath in the properties doesn't
work (found that one on an old tutorial). Running it with elevated
permissions doesn't work. Accessing apps via the network is a no-go
(that's likely my industry firewall), so I had to find a workaround to
even download the apps from the website as the "install" button tries
to communicate with Cytoscape and ends up going nowhere. But yes, for
now I"ll try running things command line with linux. And as far as
versions go, these were shiny-new ones downloaded yesterday.
