Errors with calling cortex.align.manual()

[sunjc73]

When cortex.align.manual("S1", "fullhead") was called, the error was raised as "TraitError: The 'input' trait of a DecimatePro instance is 'read only'."

When I revise the function decimate(pts, polys), no errors raised. I replaced dec = tvtk.DecimatePro(input=pd) with from tvtk.common import configure_input dec = tvtk.DecimatePro() configure_input(dec, pd)

However, the graph cannot be displayed normally. The graph was shown as:

So, as you can see, the surface cannot be shown correctly. Does anyone encounter this problem, and how to resolve it?

Has this ever been solved or is the underlying issue known? Is there any known workaround?
