The documentation suggests using an M. leprae data set (http://biosual.cbio.uct.ac.za/pinViewer.html?core=PINV_leprae). When I try this URL, the filter window pops up first and tells me there are 1412 with 27566 interactions. That's great, but whether I execute a filter or just close the window, I don't see any nodes or network graphics at all. The Table tab just provides an empty data table (complete with the label, "No data available in table").
I expect that this is the result of something specific about my system or my browser version. I'm using Chromium Version 33.0.1750.152 on Ubuntu 12.04. I tried PINV in Chrome Version 34.0.1847.131 on Win 7 and got the same result. The issue renders PINV unusable so I hope there's a quick fix! Thanks!
