For those that have already downloaded the Dynamic Networks tool: I made a small change to the tool. I noticed that, when using a sliding frame for dynamic networks, the time intervals would lead to weird behaviour in the visualizations. I therefore changed the way that time intervals are recorded for sliding frames. I uploaded an updated version of the tool (for Windows, Linux and Mac) to the software page. If you downloaded the tool before reading this post, I advise downloading the updated version.
