pyngui¶
What is pyngui?¶
pyngui is a desktop application to read, visualise and export files recorded by SnowMicroPen (pnt files).
Launch pyngui¶
When the snowicropyn package is installed, a simple script to start pyngui is registered too. Open a Terminal Window and type pyngui and hit return. A window should open which looks alike this screenshot:
Probably, this command fails to launch pyngui. Try to launch it manually then. Type:
python -m snowmicropyn.pyngui.app
or:
python -m snowmicropyn.pyngui.app
Features & Tips¶
Save your changes!¶
pyngui does not prompt or warn for unsaved changes. Don’t forget to save your markers, otherwise they will be lost.
Surface & ground¶
pyngui uses the marker labels surface
and ground
to mark the
begin and end of the snowpack. You can let pyngui auto detect
those markers for you by clicking the according icons in the toolbar.
Drift, Offset & Noise¶
For each profile, the pyngui calculates drift, offset and noise and
displays those values in the sidebar. This data is useful to check for a bad
signal. The values are calculated for a section within the signal. Where this
section starts and end is indicated in the sidebar. In case you want to specify
the section yourself, set markers called drift_begin
and drift_end
. To
simplest way to do so is context clicking into the plot.
