Profiles

Contents


Overview

QSAS allows to save user-specified parameters as a configuration file, possibly holding various profiles. Parameters include for example default behaviour on dragging and dropping multidimensional data on the plot list, default plot page parameters, and default sizes for the main window and the plot interface window. These profiles are stored on the system, in user-dependent places: /home/user/.qsasrc on Unix, and Documents and Settings/user/Application Data/qsas.ini on Windows.

The profiles are saved when QSAS is closed. Then QSAS opens with the configuration defined in the last-selected profile.


Editing and Using Profiles

The Profiles drop-down menu on the main window allows to edit (Edit profiles... item) or to select a profile as the current one (all the other entries).

Clicking Edit profiles... opens a Profiles Editor window, showing the setup for the currently-selected profile. Selecting a profile in the Load preset combo box displays the settings of this profile, discarding the possible edits made in the interface. The edits are made through various tabs, and can either be saved as a preset (possibly updating an existing preset), applied directly by clicking on Use these settings (through a "fake" preset called "Custom"). The "Default" preset cannot be overwritten, and the "Custom" preset is updated every time Use these settings is clicked, and discarded every time it is saved as a real preset.

Clicking a profile in the profiles list in the Profiles drop-down menu selects it as the current one.


Paths setup

These options are accessible in the "Paths setup" tab. The first 3 paths are only taken into account when QSAS is opened, so they must be set up in the profile QSAS opens (last profile when QSAS was closed).


Plot setup

These options are in the "Plot" tabs.

Custom colour table example

Let's define a colour table to represent heat levels for example, ranging from black for cold (low values) to red, yellow and finally white for maximum temperatures. We choose to define our colours in RGB representation. Their values are:

We now have to choose the positions of these values on the scale. Black is at the bottom of the scale, hence 0, White is at the top of the scale, hence 1. We choose to put red in the middle of the scale, and yellow at 3/4. We finally obtain the following colour table description:
RGB(0,0,0,0)(0.5,1,0,0)(0.75,0.8,0.8,0)(1,1,1,1)

A similar colour table can be achieved in HSL mode, allowing more controls on the hues, and thus avoiding muddy colours that can appear interpolating over R, G and B components:

The resulting syntax is: HSV(0,0,0,0)(.25,0,1,.5)(.75,60,1,.5)(1,60,1,1)


User interface setup

These options are in the "User interface" tab.


Miscellaneous setup

These options are in the "Misc." tab. They are debug options.
