I’m trying to implement a basic process in the Graph Builder. See attached for the graphic view of the process.
My problem is the inputs to the BandMaths(2) step, when defining the expression. It recognises the output of the Calibration step, but it will not recognise the output from the preceding BandMaths step. Therefore I am not able to define the necessary expression and the process is incomplete.
Is there an issue with multiple inputs to a BandMaths operator? Or is there another way to define this outside of the Graph Builder since I will eventually run this on the command line, not in the GUI? Any help would be very welcome.
