Issues with 4D meshes

[kephale]

Hey Friends!

I ran into an issue using nppas on a 4D mesh (json export of layer.data = https://gist.github.com/kephale/2357e3b9567f3bdedcc43c906a6de245).

The error is:

ValueError: input shape is not supported.

Since napari supports surfaces that are >3D it seems like a call like this should either throw a warning about the dimension of the input and either fail or show the results for the currently selected timestep.

Thanks for pointing this out @kephale ! We're aware of this and actually have a partial solution in napari-stress. See this issue:

• Move timelapse converter upstream campaslab/napari-stress#104
