After creating the new project, an entry mask "Project settings" is opened, where all the items should be filled in.

Open

Load a Galvani data file.
The default path for Galvani data files is ~/galvani/data/ in the user's home directory.
If the file contains unknown function names (perhaps in other languages) they can be mapped on known names. After loading the measurement data, project settings are shown. Title and comment can be edited, all other settings are read-only. Data can then be plotted in a diagram and can be evaluated.

Save

Save actual measurement data as text file.
The default path for Galvani data files is ~/galvani/data/ in the user's home directory. The default extension is ".dat".

Export

Save the actual diagram as image file.
The default path for diagram files is ~/galvani/data/ in the user's home directory.
The filename extension determines the image type (PNG, SVG or EPS).

Print

- Title of the project
- Comment
- Diagram
- Results of evaluation (peak areas of chromatograms, parameters of linear regression)

The document viewer evince must be installed for print preview.

Quit
