This section describes how you interface with the SciQt Main Window, the SciQt Main Window ancillary tools. The primary tools allowing you to load data, analyse, design and apply the Coloured Inversion operator are described in greater detail in later sections.
The Coloured Inversion main window GUI consists of, from top to bottom, a menubar area, a toolbar area, a chart area and a status area (see figure below). The chart area which occupies the large central area of the main window is used to display various charts of spectra and time data providing instant feedback to the Interpretation Geoscientist in his/her quest to design a Coloured Inversion operator. The four sub-sections which follow will provide you with a description of each of these areas. We will pay particular attention to the central chart area.
This sub-section describes the actions performed by the various menu items
| Pops up a selector to allow you to choose a project for this SciQt session (shortcut Ctrl+P). | |
| Creates a new SciQt session (shortcut Ctrl+N). | |
| Opens a previously saved SciQt session (shortcut Ctrl+O). This facility allows you to restore the SciQt parameters together with the data from a previously saved session. Restoring a previously saved session can take a few moments while database access is established. Note if the stored data within the database has been modified since the session save time, then it is possible that a different Coloured Inversion operator might be generated following a session restore then that available at the session save time. | |

This is the main functional area of the SciQt application. It is used to display various charts. These charts are used to display various spectra data and time domain data. The chart area provides graphical feedback of the various stages in the generation of the SciQt operator for the given data and program parameters supplied by you. The chart area is also dynamic, allowing you to interface directly with the charts and objects within this area. You can interactively update these charts in real time by modifying the various parameters in the "Select Input Data" dialog, "Design Operator" dialog and the "Advanced Controls" dialog. We call this data driven, as the effect of you modifying a parameter within the above dialogs is an immediate update to the graphical charts. Whereas, in earlier versions of the software it was necessary to click a push button at every stage to see an update.
By default ten charts are generated as below:
| SciQt Main Window (showing top four charts) | Description of top four charts with the default data objects |
|---|---|
 | Chart 1 Raw Seismic - This chart displays the raw gated seismic trace spectra. By default, a random set of 40 seismic traces within the 3D Survey Area is loaded when the push button is clicked. This push button is located within the "Input Seismic" tab on the "Select Input Data" dialog. Changing the time gate and/or range mode will update this chart. It is recommended that if an interpreted horizon (with few undefines) is available within the target area then Range mode (radio button) be set to "Horizon" Chart 2 Seismic Mean - This chart displays the mean seismic spectrum. The mean seismic spectrum (red) is derived from the raw gated seismic trace spectra in chart 1. Clicking the button within the "Input Seismic" tab on the "Select Input Data Dialog" will update the data on this chart. Also displayed on this chart is a smooth mean seismic spectrum (black). The amount of smoothing can be controlled by you interacting with the Smooth Seismic Mean control on the "Design Operator Dialog". Chart 3 Log Input (time domain) - This chart displays the selected gated AI log data in time. In this example only one AI log has been selected. Selecting AI log data or clicking the button in the "Input Well Log" tab on the "Select Input Data Dialog" will update the data on this chart. Also displayed on this chart is the linear trend line (black). Controls on the "Advanced Controls" dialog can also have an immediate effect on this chart. Chart 4 Log Input Detrend (time domain) - This chart displays the selected gated AI log data in time with the linear trend line remove. In this case, end ramping has also been applied so the log ends intercept the zero axis. Selecting AI log data or clicking the button in the "Input Well Log" tab on the "Select Input Data Dialog" will update the data on this chart. Controls on the "Advanced Controls" dialog can also have an immediate effect on this chart. |
| SciQt Main Window (showing middle four charts) | Description of middle four charts |
 | Chart 5 Individual Wells - This chart displays the individual AI log spectra. As there was only one AI log selected in this example, there is only one log spectrum to be displayed. Selecting AI log data or clicking the button in the "Input Well Log" tab on the "Select Input Data" dialog will update the data on this chart. Chart 6 Global - This chart displays the mean (or global) of the individual AI log spectra. In this example, there is only one individual AI log spectrum so the global spectrum is the same as the single individual AI log spectrum. Also displayed on this chart is the curve fit spectrum (black). Various controls on the "Design Operator" dialog and in the "Advanced Controls" dialog can have an immediate effect on this chart. Chart 7 Design Operator - This chart displays three curves: The curve coloured "red" is the smooth mean seismic spectrum. The "green" curve is the band-limited spectrum derived from the smooth composite curve fit to the average AI spectrum. Finally, the "blue" curve is the band-limited shaping operator. Note: the maximum frequency of the chart is determined by the maximum nyquist frequency of either the log data or the seismic data. Various controls on the "Design Operator Dialog" and in the "Advanced Controls" dialog can have an immediate effect on this chart. Chart 8 Operator (time domain) - This chart displays the time converted Coloured Inversion operator. Various controls in the "Select Input Data" dialog, "Design Operator" dialog and "Advanced Controls" dialog can have an immediate effect on this chart. |
| SciQt Main Window (showing bottom two charts) | Description of bottom two charts |
 | Chart 9 Residual Operator (QC) - This chart displays the following spectra and is used for QC purposes.
Various controls in the "Select Input Data" dialog, "Design Operator" dialog and "Advanced Controls" dialog can have an immediate effect on this chart. Chart 10 Convolved Output Mean (QC) - This chart displays mean Coloured Inversion data (red) and the smooth mean Coloured Inversion data (black). Various controls in the "Select Input Data Dialog", "Design Operator Dialog and "Advanced Controls" dialog can have an immediate effect on this chart. |
The status area at the bottom of the main window is used to display various messages and other information to the user. For example, if you pass the mouse over a toolbar icon then a tip is displayed in this area indicating what is the purpose of the icon. The status area is also used to display information about a given chart as the mouse passes over the central area of the main window.

| The picture to the left shows the SciQt main window with the status area displaying information about central chart area. Here the user has moved the mouse (the mouse not visible on the screen capture) over the LH chart. The status area displays the title of the chart "Residual Operator (QC)" together with the location of mouse in units of the chart. Also displayed are the titles of the axis. |
There are various main window ancillary tools within the SciQt application which you might find helpful and deserve a mention. These are Save Operator, Export Operator, Export Data Item and Parameter Report.
The Save Operator tool allows you to save an operator to a database. Clicking the menu item will pop up the "Save Operator" dialog. If you haven't saved the operator during your session or if the operator has changed since you lasted saved it, then you will be prompted to save the operator before the SciQt program exits.
| Save Operator dialog | Description |
|---|---|
 | The picture to the left shows the "Save Operator" dialog. This allows you to select a previously saved SciQt operator or to specify a new SciQt operator. Either way when you click the [Save] push button the current time domain operator will be saved to the database by the name in the Select Operator input field. If the operator already exists in the database you will be warned that you are about to overwrite the operator. |
The Export Operator tool allows you to export an operator to an ASCII file. Clicking the menu item will pop up a file selector dialog. Here you can traverse the file system to export the SciQt operator as an ASCII file.
This is a power ancillary tool which allows you to export any of the loaded or generated data items (time or frequency domain curves) to an ASCII file. Clicking the menu item will pop up the "Export Data Item" dialog.
| Export Data Item dialog | Description |
|---|---|
 | The picture to the left shows the "Export Data Item" dialog. This dialog contains a list view widget which allows you to export, to an ASCII file, either: all the data items for every group, all the data items for a single group or a single data item from a group. This is achieved as follows: All Data Items: Clicking the "All Data Items" on the "Export Data Item" dialog will select every data item currently available. Then by clicking the [Export] push button you will be given a file selector dialog allowing you to save all these data items into single ASCII file. Group Item: Click one of the groups beneath the "All Data Items" will select that group. Then by clicking the [Export] push button you will again be given a file selector dialog allowing you to save the group data into a single ASCII file. Data item: Click a data item within a group will select that data item. Then by clicking the [Export] push button you will once again be given a file selector dialog allowing you to save the data item to a single ASCII file. You can optionally output a header. This is useful if you are outputting two or more data items. |
This ancillary tool allows you to display and optionally save the SciQt parameters in a nicely formated manner. Clicking the menu item will pop up the "Parameter Report" dialog.
| Parameter Report dialog | Description |
|---|---|
 | The picture to the left shows the "Parameter Report" dialog. This dialog displays the key parameters in the SciQt analysis and design phase nicely formated. Click the [Save As] push button will pop up a file selector dialog allowing you to save to an ASCII file the formated parameter report. |
