parameter_sweeping

[kahntm]

Right now the parameter sweeping allows to load the data, build everything, stop just shy of the reconstruction and save the state. Later you define engine parameters, run a reconstruction, save the final state, load the pre-reconstruction state, define other reconstruction parameters, run the reconstruction with the new different parameters and so on ...

This does not allow to sweep parameters that are defined and used prior to the reconstruction.
Things that I sweep with an outer wrapper script again and again are:

• detector distance
• rotation / skew of the recorded positions (parameters in the NanoMAX data loader class for the case that physical motor stages are not exactly parallel / perpendicular to the detector pixel grid and each other)

Other things that have been mentioned in ptypy workshop:

• defocus value of the probe (which phase curvature to start with) -> already possible but Benedikt needs to make an example
