Option: Relative Values
To compare data from different experiments, absolute values from individual experiments are
usually normalized on the baseline of the respective experiment. This can be done automatically
in LTP-Analyzer before exporting the data as ASCII file.
After the analysis is finished, click the icon "Show relative values" in "Analyzer Mode".
The analyzed data values are recalculated relative to the first phase of your experiment,
"Baseline", "Drug Application" or "Washout". Which phase is used as baseline is displayed in
the data trace window. If none of these three phases was used as first phase in the recording,
no relative values can be calculated.
All absolute values of the underlying baseline are averaged, and all data points are calculated
relative to this average. The result is plotted in the parameter trace window instead of the
absolute values. This option is only available after a successful analysis.
Relative data can be exported as ASCII file and directly averaged over several experiments,
for example, in Excel or Origin.
