gwyddion - SPM data visualization and analysis


gwyddion [OPTION...] [FILE...]


Gwyddion is a graphical SPM (Scanning Probe Microscope) data visualization and analysis program, using Gtk+.


The program accepts all standard Gtk+, Gdk, and GtkGLExt options like --display or --sync. Please see documentation of these packages for description of toolkit options.

The behaviour of the remote-control options --remote-* is undefined when more than one instance of Gwyddion is running on the display. They can choose an arbitrary instance to communicate to.

Gwyddion options:


Prints a brief help and terminates.


Prints version information and terminates.


Disables splash screen on program startup.


Opens files given on the command line in an already running instance of Gwyddion on the display. Runs a new instance if none is running.
This is probably the most useful remote control option. File type associations are usually installed to run Gwyddion with this option.


Opens files given on the command line in an already running instance of Gwyddion on the display. Fails if none is running.
This is useful if you want to handle the case of Gwyddion not running differently than by starting it.


Succeeds if an instance of Gwyddion is already running on the display and prints its instance identifier. Fails if none is running.
The instance identifier depends on the remote control backend in use. In some cases it is useful as a global window identifier, in some it is not. With libXmu this option prints the X11 Window, on Win32 HWND is printed, while with LibUnique the startup id is printed.


Instead of running the user interface and opening FILEs, it loads the files, performs a sanity check on them (printing errors to standard error output) and terminates.


Redirect messages from GLib, Gtk+, Gwyddion, etc. to ~/.gwyddion/gwyddion.log or file given in GWYDDION_LOGFILE environment variable. Note messages are always redirected to a file on Win32 so, this option has not effect on Win32.


Prints list of objects created during run time, with creation and desctruction times or reference counts on program exit. Useful only for developers.


Prints wall-clock time taken by various startup (and shutdown) tasks. Useful only for developers and people going to complain about too slow startup.


On Linux/Unix, following environment variables can be used to override compiled-in installation paths (MS Windows version always looks to directories relative to path where it was installed). Note they are intended to override system installation paths therefore they are not path lists, they can contain only a single path.


Base data directory where resources (color gradients, OpenGL materials, ...) were installed. Gwyddion looks into its gwyddion subdirectory for resources.
When it is unset, it defaults to compiled-in value of ${datadir} which is usually /usr/local/share.


Base library directory where modules were installed. Gwyddion looks into its gwyddion/modules subdirectory for modules.
When it is unset, it defaults to compiled-in value of ${libdir} which is usually /usr/local/lib or /usr/local/lib64.


Base lib-exec directory where plug-ins were installed. Gwyddion looks into its gwyddion/plugins subdirectory for plug-ins.
When it is unset, it defaults to compiled-in value of ${libexecdir} which is usually /usr/local/libexec.


Locale data directory where message catalogs (translations) were installed.
When it is unset, it defaults to compiled-in value of ${datadir}/locale which is usually /usr/local/share/locale.

Other variables that influence Gwyddion run-time behaviour include m[blue]GLib+ variablesm[][1] and m[blue]Gtk+ variablesm[][2] and some Gwyddion-specific variables:


Name of file to redirect log messages to. On MS Windows, messages are always sent to a file as working with the terminal is cumbersome there. The default log file location, gwyddion.log in user's Documents and Settings, can be overriden with GWYDDION_LOGFILE. On Unix, messages go to the terminal by default and this environment variable has effect only if --log-to-file is given.



Saved user settings and tool states. Do not edit while Gwyddion is running, it will overwrite it at exit.

~/.gwyddion/glmaterials, ~/.gwyddion/gradients, ...

User directories with various resources (OpenGL materials, color gradients, ...).

$GWYDDION_DATADIR/gwyddion/glmaterials, $GWYDDION_DATADIR/gwyddion/gradients ...

The same for system-wide resources.


Directory to place user icons to. This is mainly useful for installation of modules to home.


The same for system-wide icons.


Directory to place user modules to. They should be placed into file, graph, process, layer, and tools subdirectories according to their kind, though this is more a convention than anything else.


The same for system-wide modules.


Directory to place user plug-ins to. They should be placed into file and process subdirectories according to their kind.


The same for system-wide plug-ins.


Directory to place user python modules or scripts to.
