Float index in coregistration gui

@christianbrodbeck I have a problem with the source alignment example - I get the following error when trying to open the GUI:

TypeError: list indices must be integers or slices, not float

Seems that index is a float, but I don’t know how it gets to that point.

Hm yeah then we should update the conda-forge recipe once a new version is released…
