Is it possible to call resetSlider method?  
reformatLogic = slicer.modules.reformat.logic()  
reformatLogic.RotateSlice(sliceNode, 0, rotateX)  
reformatLogic.RotateSlice(sliceNode, 1, rotateZ)  
reformatLogic.RotateSlice(sliceNode, 2, rotateY)  
Cause when I change the above rotation, the result will be wrong if not calling resetSlider.  
Thanks!

@derekcbr, what is the effect that you consider wrong? Is it that the GUI is not updated accordingly?

Is it possible to use python to update sliders in GUI? qSlicerReformatModuleWidget

@derekcbr, I’m understanding that your question is due to a mismatch between the reslice rotations you try to implement in python and the UI of the `reformat module`. Based on that:

- The `reformat module` is a loadable module where UI, data model and logic are tightly integrated. Modifications on the data model (e.g., MRML nodes) should be correctly reflected in the UI and vice-versa; logic typically modifies the data model, which in turn, should correctly update the values in the UI.

- You should not need to adjust the UI to reflect changes you produce by changing MRML nodes or invoking public logic functions. This could be a bug int he `reformat module`. Do you have data + python snippet to reproduce the issue. Maybe it is something that should be reported and fixed
