Hello,

I am running an ab intitio reconstruction of my own dataset and I keep getting the following error:

Traceback (most recent call last):

RuntimeError: Astigmatism angle is outside [-2 pi, 2 pi]: -9.81032166377 rad, -562.090027 deg. Likely a missing degrees to radians conversion.

This error appears early in the reconstruction, usually after iteration 4 or 5. I have tried this with a single class and multiple classes and the same error occurs. Is this a problem with the data set? Is there a way to manually convert degrees to radians in my dataset?

Thank you.
