Displaying SEGY data: The Display menu
This function will open all the highlighted SEGYs in
SegyTool.
There must be a valid, accesible, license for SegyTool to use this option.
Note that SegyTool must be started by SegyTracker, if SegyTool is already running the
SEGYs will only be imported if the instance of SegyTool was started by this instance
of SegyTracker.
All the highlighted SEGYs will be added to the
SegyTool working set .
There is no limit to the number of files that can be added to the working set.
Changes made to the SEGYs in SegyTool will not appear in SegyTracker until the
Reload Segys function is chosen.
This function will reload all the highlighted SEGYs into the
current table. Use this function if you edit files from the table in
SegyTool.
This function will display the EBCDIC header for the first highlighted
SEGY in the current table.
By default the header is assumed to be written in EBCDIC format but
clicking the "ASCII" radio button will display the header in ASCII.
If viewing the header in EBCDIC you can rewrite the header in ASCII format to the SEGY file
by clicking the "Eb2Asc" button. Conversely you can convert the header from
ASCII to EBCDIC by clicking the "Asc2Eb" button.
This dialog will not be refreshed when traversing rows using the keyboard up and down arrow keys.
To refresh the dialog you must traverse using the up and down arrows on the bottom status panel.
This function will display all highlighted 2D SEGYs on a
Qdmap display.
You must ensure that all the highlighted SEGYs are in fact 2Ds.
A map display parameters
dialog will pop up before the map is displayed.
You must ensure that all the highlighted SEGYs have the shotpoint, X, and Y in the same format
and byte location.
If you have SEGYs with these values in various formats or bytes locations you can add SEGYs to
the map in multiple passes changing the read parameters each time.
This function will display all highlighted 3D SEGYs on a
Qdmap display.
You must ensure that all the highlighted SEGYs are in fact 3Ds and have the inline, xline, X, and Y in
the same byte locations and format.
As above a map display parameters
dialog will pop up before the map is displayed.
Wiggle trace display parameters
Use the trace display parameters
dialog to set the parameters for a wiggle trace display. These parameters can be set before or after the wiggle trace display is
created.
This function will create a 2D
wiggle trace display from the SEGY in
the first highlighted row.
This display will not be refreshed when traversing rows using the keyboard up and down arrow keys.
To refresh the display you must traverse using the up and down arrows on the bottom status panel.
This function will create a 3D
wiggle trace display from the SEGY in
the first highlighted row.
Before creating the display a dialog will query you on the byte location and format of
the inline and xline numbers. If necessary use the trace display
parameters to change the settings.
This function will display the first highlighted SEGY in the
diagnostic dashboard
display which shows various attributes of a SEGY file such as shotpoint and XY range, EBCDIC header,
a histogram, and a wiggle trace display.
This dialog can be very useful when examining a large number of SEGYs prior to data loading.
As above this dialog will only be refreshed when using the up and down arrows on the bottom panel.
Show histogram or amplitude graph of SEGY file
This function will display a
histogram or graph of the data samples in the first highlighted SEGY.
As above this dialog will only be refreshed when using the up and down arrows on the bottom panel.
This function will create charts of the numeric data in one or more columns. The user can choose a
line chart, area chart, or bar chart and set the colours for each. The chart display will also display the min and max values from each column
This function will highlight the rows containing unpadded 3Ds, that is
3Ds that do not have a constant number of xlines per inline.
The table must contain the columns for first and last inline, first and last xline, and number of traces.
The inline and xline values are used to determine the theoretical number of traces in the 3D. If this number does not
match the actual number of traces the row is highlighted.
Unlike the other functions on this menu this function works on all the rows of the current table
whether highlighted or selected.
