With Variable, you can store any single numerical value. This value is identified by a unique name. You can provide either only a static name for the variable, or use a dynamically generated key in addition (for example, the sample name).
The variable AvgRetTime may contain the average retention time of a specific compound found in a specific sample.
The variable AvgRetTime (Sample_Name) can be created once for each sample in a sequence. With AvgRetTime("SSRSD1"), you can show the average retention time in the SSRSD1 sample. If the variable is embedded in a composite group that is repeated on the sample name, you can automatically list the average retention times for each sample.
