How do I create a custom field in Empower to determine Similarity Factor? - WKB301604

Article number: 301604

ENVIRONMENT

  • Empower 3
  • Empower

ANSWER

Create a Peak Type Custom Field. Generally speaking, the Search Order should be set to Result Set Only.

Use this formula: (S2.%.SAME.AVE(Response)/S2.%.SAME.AVE(Response))*(S2.%.% (Value)/ S1.%.% (Value))

The average response values are calculated by averaging all the response values from results of all injections with the specified label (S1 or S2). 

  • The SAME string specifies that only responses from the same channel results are averaged.

  • The % character specifies that the responses from all the injections that match the label and channel criteria are averaged.

The Value to be used is any Value from a result with the specified label. (The value is the same for all results with the same label.)

  • The first % character specifies that the Value to be used is from a result from any of the channels in that injection.

  • The second % character specifies that the Value to be used is from a result from any of the injections (any channel).
