Hi Josh,
Thank you so much for sending the app! I have taken a look at it and now I know why you are getting the error. The reason is from the code on line 377:
NTA_SubScript(app, Histo_Plot, Int_Plot, data, 0)
Now, the input argument "data" is expected to be a struct created from "readtable" of the CSV file selected. I verified that "readtable" works on the CSV file given. However, the "data" variable that is getting populated is a local variable of the "Run1ButtonPushed" callback. Once you are inside the "RunButtonPushed" callback, the "data" variable is a new local variable created, with default value being empty, and hence if you place a breakpoint on this line, and examine the value of "data", you get:
data = []
Therefore, when you are trying to access
data.IncludedInDistribution_
You get the error:
Struct contents reference from a non-struct array object.
As expected, because you are trying to get a struct content, "IncludedInDistribution_" from a supposedly struct "Data". However, "Data" is null.
In order to fix this issue, a workaround is to assign a property, such as "Data" in the perperties block of the app, and access the data as "app.Data". That way, the variable "app.Data" will be globally accessed by all callback functions.
Thanks,
David
