      Description

      Hi Lia,

      should it be possible to display results of a surface simulation within TVB ?
      E.g. I use the default connectivity and surface with ~16k vertices.
      So this will generate ~16k timeseries.
      When I try the 3D brain visualization I get the following screen#1.
      With the message "Could not retrieve data from server."

      When displaying 2D timeseries I can only select form the first 100 signals.
      See screen#2.
      Also the numbers of signal are not linked to any region.
      I guess one could look this up in the regionmapping file, but it would be cool to see it within the GUI.

      I wonder if this is a technical problem or/and a visual problem due to the large data size and amount of vertices to plot ? I guess it could be difficult for the viewer to extract relevant information from such a crowded plot.

      Another thing I just noticed is the local parameters of the JansenRit model.
      There is parameter: "a", "b" and again "a", "b".
      In my opinion the first two should be capital letters to follow the original naming in the paper from 1995 and also to distinguish between them.

      best
      Paul
