Data analysis

TOPPView also offers limited data analysis capabilities for single layers, which will be illustrated in the following sections. The functionality presented here can be found in the Tools menu.

TOPP tools

Single TOPP tools can be applied to the data of the currently selected layer. The following example image shows the TOPP tool dialog:

After selecting a tool, the algorithm parameters can be edited manually, or loaded from an INI file. The results can then be displayed as a new layer of the same window or in a new window.

Metadata

One can access the metadata the layer is annotated with. This data comprises e.g. contact person, instrument description and sample description.

Note:
Identification data, e.g. from a Mascot run, can be annotated to the spectra or features, too. After annotation, this data is listed in the metadata as well.

Statistics

Statistics e.g. about peak/feature intensities can be displayed. For intensities, it is possible to display an additional histogram view.
