Hi Liz,

Just so people don’t get confused, I think you are refering to the ZPL macro langage. Because this setting is available in the ZOS-API. Here is a Python example that demonsrates how to set the polarization flag:

# Open a new Geometric Image Analysis
geo_imag_analysis = TheSystem.Analyses.New_GeometricImageAnalysis()

# Retrieve the settings of this analysis
geo_imag_settings = geo_imag_analysis.GetSettings()

# Toggle the polarization flag
geo_imag_settings.UsePolarization = True

# Apply settings and run the analysis
geo_imag_analysis.ApplyAndWaitForCompletion()

Take care,

David

Hi David, 

Is there a way to extract the percent efficiency using the zos api?

# get results
geo_imag_results = geo_imag_analysis.GetResults()

# extract percent efficiency

The output I’m looking for would be the same as what I can calculate with IMAE in the merit function. 

In this post, @MichaelH discusses saving and then parsing a .txt file with this information. Do you know if there is a quicker/more streamlined way to do this? 

Thanks!

Hi @liz_strong,

The results of geometric image analysis aren’t fully implemented as I can tell. So, parsing the text file seems the way to go as @MichaelH suggested.

I’m not sure if that’s what you want, but you can also evaluate a single Merit Function operand, such as IMAE, with the GetOperandValue method from the Merit Function Editor interface.

In Python, you’d do something like so:

from ZOSAPI.Editors.MFE import MeritOperandType

efficiency = TheSystem.MFE.GetOperandValue(MeritOperandType.IMAE, 0, 0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0)

print("Efficiency: " + str(efficiency * 100) + "%")

The ouptut looks like so:

Efficiency: 100.0%

Does that help?

Take care,

David

Yep, thanks David!
