Introduction

TOPPView is a viewer for MS and HPLC-MS data. It can be used to inspect files in mzData, mzXML, ANDI/MS and several other text-based file formats. It also supports viewing data from an OpenMS database.

In each view, several datasets can be displayed using the layer concept. This allows visual comparison of several datasets as well as displaying input data and output data of an algorithm together.

TOPPView is intended for visual inspection of the data by experimentalists as well as for analysis software by developers.

The above example image shows a 2D view of TOPPView (blue rectangle) and the corresponding Display and action modes (red rectangle). In the right dock area, you can see the Layers (yellow rectangle) and the Data filtering tool.

Layers

Each view of TOPPView supports several datasets, called layers. In the layer manager, dock window, layers can be hidden and shown using the checkbox in front of each layer name.

By clicking on a layer, this layer is selected, which is indicated by a blue background. The selected layer can be manipulated using the Tools menu.

Note:
Opening two or more datasets in different layers of one window is possible from the command line, too. Execute TOPPView --help for more information.

Data filtering

TOPPView allows filtering of the displayed peak data and feature data. Peak data can be filtered according to intensity and metadata. Metadata is arbitrary data the peak is annotated with. Feature data can be filtered according to intensity, charge, quality and metadata.

Data filters are managed by a dock window. Filters can be added, removed and edited through the context menu of the data filters window. For convenience, filters can also be edited by double-clicking them.

Looking for help?

You can display a short help text for each button and dock window of TOPPView by clicking on it in What's this? mode. What's this? mode can be entered using the Help menu.
