We can first check if the certain analysis has setting interface by using the HasAnalysisSpecificSettings property:

my_analysis.HasAnalysisSpecificSettings

If settings are available, then settings can be configured directly. 



Or we can search from OpticStudio helpfile to see if the analysis supported by ModifySettings methods, since the use of the method is similar to ZPL keywords, so we can check supported analysis and type code from the following chapter in helpfile:  

The Programming Tab > About the ZPL > KEYWORDS (about the zpl) > MODIFYSETTINGS (keywords)

If settings are supported by MODIFYSETTINGS, the settings can be configured by using ModifySettings method. 

 

If none of the above situations apply for the application, a workaround is provided. 



After compare the three analysis features, we found that: 

	HasAnalysisSpecificSettings	supported by ModifySettings?	type code for Modifysettings
Spot Diagram	True	Yes	SPT_RAYS
Extended Diffraction Image Analysis	False	Yes	EXD_FILESIZE
Partially Coherent Image Analysis	False	Yes	NA

The following code snippet is written with Python

For Spot Diagram ：

newSpot = TheApplication.PrimarySystem.Analyses.New_StandardSpot()

print("Spot has analysis specific settings? ", newSpot.HasAnalysisSpecificSettings) # True; no ModifySettings

newSettings = newSpot.GetSettings()

spotSet = CastTo(newSettings, "IAS_Spot") # Cast to IAS_Spot interface; enables access to Spot Diagram properties

spotSet.RayDensity = 15

newSpot.ApplyAndWaitForCompletion()

or 

TheSystem=TheApplication.PrimarySystem

newSpot=TheSystem.Analyses.New_StandardSpot()

print(newSpot.HasAnalysisSpecificSettings)

newSettings=newSpot.GetSettings()

import os

cfgFile=os.environ.get('Temp')+'\\spt.cfg'

newSettings.SaveTo(cfgFile)

newSettings.ModifySettings(cfgFile,'SPT_RAYS',15)

newSettings.LoadFrom(cfgFile)

newSpot.ApplyAndWaitForCompletion()

For Extended Diffraction Image Analysis :

TheSystem=TheApplication.PrimarySystem

newEDIA=TheSystem.Analyses.New_Analysis(constants.AnalysisIDM_ExtendedDiffractionImageAnalysis)

print(newEDIA.HasAnalysisSpecificSettings)

newSettings=newEDIA.GetSettings()

import os

cfgFile=os.environ.get('Temp')+'\\spt.cfg'

newSettings.SaveTo(cfgFile)

newSettings.ModifySettings(cfgFile,'EXD_FILESIZE',0.855)

newSettings.LoadFrom(cfgFile)

newEDIA.ApplyAndWaitForCompletion()

For Partially Coherent Image Analysis:

TheSystem=TheApplication.PrimarySystem

newPCIA=TheSystem.Analyses.New_Analysis(constants.AnalysisIDM_PartiallyCoherentImageAnalysis)

print(newPCIA.HasAnalysisSpecificSettings)
