Exporting data

The FileExport File function of OVITO exports the results of the current data pipeline to a file. Depending on the selected output format (see table below), different fragments of the dataset are exported, e.g. the particles and their properties, the bonds, other computed quantities, etc. Furthermore, you can choose which animation frame(s) should be exported (just the current frame or a range), and whether the datasets are saved to a single output file or to a sequence of files, one per frame.

OVITO will ask you for a destination filename. Note that, if you append the .gz suffix, the output file(s) will automatically be compressed for text-based file formats.

Exporting scalar values

Some of OVITO's analysis functions produce single output values (in contrast to per-particle property values), e.g. the total number of atoms of a particular type or the computed surface area of a solid. Such global quantities computed by the pipeline system may be time-dependent (i.e. the are recomputed on every frame) and thus represent time series.

For exporting a time series of one or more such values, OVITO provides the "Table of Values" format. This output format generates a table with the selected quantities as functions of time and saves it as a plain text file. You can then plot the exported data with an external tool of your choice.
