This section describes the workflow to approach the translation from an application note (or other documentation) into Custom Calculation formulas.
List the results expected by your application.
Identify the results that are not computed by default by Data Analysis.
This can be quite difficult. You can use the Agilent OpenLab CDS Data Analysis Reference Guide to be sure to not repeat calculations that are already made by default.
Exclude those that cannot be done with Custom Calculator (for example, across different result sets, direct reading of raw data, spectra).
For each result not computed by default, identify the results computed by Data Analysis that can be used as input for the formula.
Are they sufficient? Do you need additional inputs?
If you need additional inputs, determine how you can provide them.
For example, special naming of compounds or samples, usage of an external constant file in the Custom Calculation editor, or custom parameters (compounds or sample) entered in the Control Panel.
Intermediate Custom Calculation: Here you have to decide what is the most suitable for you.
Setup a reference data set.
Obtain the expected results: compute them manually or, for example, in Microsoft Excel. Use legacy Software.
Start creating your Custom Calculations. Proceed incrementally.
Verify the results.
When a result set is ready and saved with Custom Calculation results, create the report template.
