All baseline correction reports include a Plots section. The Plots section contains a single-view tab and a multi-view tab. In addition to a Plots section, the Parametric Baseline Correction report also includes a Controls section. See Parametric Baseline Correction Options.
The single-view tab shows one plot at a time. The plot corresponds to a single function and shows the original data, the baseline correction function, and the corrected function.There are drop-down menus and arrows above the graph that enable you to interactively select the function that is shown. If you specified a validation set, the first drop-down menu enables you to select whether the plot that is shown is for the training or validation set. Plots of the validation set show only the original data, because baseline correction is not performed on the validation set. The second drop-down menu and the arrows enable you to view the different functions.
The multi-view tab shows multiple functions in a grid of up to 20 plots. There are drop-down menus and arrows above the grid that enable you to interactively select the plots that are shown. If you specified a validation set, the first drop-down menu enables you to select whether the plots that are shown are for the training or validation set. If there are more than 20 functions, the second drop-down menu and the arrows enable you to view different groups of plots.
The following options are available as buttons in the Plots section:
Save Corrected
Adds the baseline corrected functions as a step in the Steps list of the Data Processing report. You can then fit a functional model to the corrected data. Once you click the Save Corrected button, the current baseline correction report closes.
Save Baselines
Adds the baseline functions as a step in the Steps list of the Data Processing report. Once you click the Save Baselines button, the current baseline correction report closes.
You can remove a baseline correction report by clicking the corresponding baseline correction red triangle and selecting the Remove Fit option.
If you select the Launch Parametric Baseline Correction option, there are several options that enable you to manually specify a baseline model. The baseline correction report for the parametric baseline correction method contains the following options:
Baseline Model
Specifies the type of model for the baseline function. You can specify a linear, quadratic, cubic, two-parameter exponential, or three-parameter exponential model.
Correction Region
Specifies the region from which the baseline function is subtracted. You can subtract the baseline from the entire function region or from only the regions that were used to construct the baseline model.
Baseline Regions
Adds or removes a pair of blue vertical lines to the selection plot. The lines are initially on top of one another. Move the lines to specify regions of the data that you do not want to include in the baseline model. The region of the data that falls in between a pair of blue lines is not included in the baseline model.
Anchor Points
Adds or removes a red vertical line to the selection plot. This line specifies data points that are forced into the baseline model.
Fit Parametric Baseline
Performs the parametric baseline correction based on the specified options. Once this option is selected, the baseline functions and corrected functions are shown in the Plots section.
