Hi harry,

If those codes are not in available in MODIFYSETTINGS, I doubt you’ll be able to do it in ZPL.

The first thing to do to check how the settings of an analysis in the ZOS-API can be modified is to check the HasAnalysisSpecificSettings property. If you run the code below (Python):

# New Geometric MTF Analysis
geo_mtf = TheSystem.Analyses.New_GeometricMtf()

# Check if settings are implemented
if geo_mtf.HasAnalysisSpecificSettings:
    print('Geometric MTF has its settings implemented in the ZOS-API')

You should get the following result:

Geometric MTF has its settings implemented in the ZOS-API

What this means is that the settings of Geometric MTF are directly available from the ZOS-API. You can find them in the ZOS-API Syntax Help (ZOSAPI.Analysis.Settings.Mtf.IAS_GeometricMtf Interface Reference):

This is a small Python example for you:

# New Geometric MTF Analysis
geo_mtf = TheSystem.Analyses.New_GeometricMtf()

# Get settings of analysis
geo_mtf_set = geo_mtf.GetSettings()

# Modify wield
field = 1
geo_mtf_set.Field.SetFieldNumber(field)

# Modify wavlenegth
wave = 1
geo_mtf_set.Wavelength.SetWavelengthNumber(wave)

# Modify sampling
sampling = ZOSAPI.Analysis.SampleSizes.S_32x32
geo_mtf_set.SampleSize = sampling

# Use polarization
geo_mtf_set.UsePolarization = True

# Apply settings
geo_mtf.ApplyAndWaitForCompletion()

I hope this helps, and take care,

David
