PROGRAM:

NAME


gwyddion - SPM data visualization and analysis

SYNOPSIS


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

DESCRIPTION


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

OPTIONS


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.

If a directory is given as FILE argument the program opens a file chooser in this
directory.

Gwyddion options:

--help
Prints a brief help and terminates.

--version
Prints version information and terminates.

--no-splash
Disables splash screen on program startup.

--remote-new
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.

--remote-existing
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.

--remote-query
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.

--check
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.

--disable-gl
Disables OpenGL entirely, including any checks whether it is available. This option,
of course, has any effect only if Gwyddion was built with OpenGL support and one of
the most visible effects is that 3D view becomes unavailable. However, you may find it
useful if you encounter a system so broken that even checking for OpenGL capabilities
leads to X server errors.

--log-to-file
Redirect messages from GLib, Gtk+, Gwyddion, etc. to ~/.gwyddion/gwyddion.log or file
given in GWYDDION_LOGFILE environment variable. This option is most useful on Unix as
on Win32 messages are redirected to a file by default.

--no-log-to-file
Prevents redirection of messages from GLib, Gtk+, Gwyddion, etc. to a file. This is
most useful on Win32 (where messages are redirected to a file by default) provided
that stdout and stderr go somewhere you can see them.

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

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

ENVIRONMENT


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.

GWYDDION_DATADIR
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.

GWYDDION_LIBDIR
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.

GWYDDION_LIBEXECDIR
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.

GWYDDION_LOCALEDIR
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 GLib+ variables[1] and
Gtk+ variables[2] and some Gwyddion-specific variables:

GWYDDION_LOGFILE
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.
