Analysis Project Menu
To access the context menu for an analysis project, open an existing solution in VGB (File > Open Solution) and right-click on an analysis gesture project (.a) in the Explorer.
The Analysis Project menu displays options for adding clips and analyzing the gesture detector.

The following options are available for the analysis project.
| Menu Option | Description |
|---|---|
| Add Clip | Adds one or more clips (.xef) to the project. |
| Analyze | Enables you to test a gesture database (.gba or .gbd) using all of the clips in the analysis project. Analyzes how well the detector results of the analysis clips compare to the tags on the clips in the training project. Analysis results will appear above the Timeline control. This option is disabled when another analysis or build is in progress. .gif) Note
You can also use this option to view the results of a data file (.adf) that is exported from a previous analysis (or created by using the -analyze option in the command-line tool).
|
| Save | Saves all changes to the analysis project (a.vgbproj), including clip references. |
| Remove | Removes the analysis project from the solution. |
| Live Preview... | Launches VGBView with the selected gesture database. |
Analysis Project Settings
The analysis project settings are available in the Properties tab and enable you to modify analysis values, such as mirroring. The settings that are available depend on the detection technology that is used by the gesture project. For more information see Detection Technologies.

Analysis Project Results
Analysis progress will be displayed in the Output pane. When analysis completes, the Project Analysis Results will be displayed above the Timeline control. Multiple analysis results can be loaded for side-by-side comparison.
If the analysis project (.a) has focus, then the collective results for all of the clips in the project will be displayed.

The following options are available in the Project Analysis Results pane:
| Control | Description |
|---|---|
| Results | Shows the project analysis results. The results contain the number of frames compared, worst errors, average RMS, false positives, and false negatives.Applicable results will depend on the detection technology used by the gesture project. |
| Clear | Clears all the existing analysis results. |
| Export | Exports the selected analysis results to an .adf file, which can be loaded later for comparing results with another build. |
To view the Clip Analysis Results, expand the analysis project in the Explorer pane and select the clip. The Timeline will then update to show the individual clip analysis results overlaid by the tags for easy frame-by-frame comparison.
