Editing/Adding text/EBCDIC header information
This module helps to edit or assign the text header/EBCDIC header information. Text header information is very useful for the interpreters and/or the processing contractors to go through the processing history of the dataset(s). In the Text header, all the processing history, acquisition parameters, grid information etc. included.
Input data tab is disabled for this module. The user must provide all the input data information in the parameters tab.
Seismic filename - provide the input seismic/SEGY file path.
EBCDIC filename - provide the input text header/EBCDIC header file path.
Skip -By default, FALSE(Unchecked). This option helps to bypass the module from the workflow.
Table Text Header - generates the output text/EBCDIC header.
There is no information available for this module so the user can ignore it.
In this example workflow, we provide the seismic and text/EBCDIC header files path. Later, we change the text/EBCDIC header information by using the action items ""Set text header from buffer".
Launch vista items "Text header". It will display the current Text/EBCDIC header information.
To edit/add anything to this existing Text/EBCDIC header, click on "Set text header from buffer" option from the action items menu.
A pop-up window opens with a caption "Please, paste text header here...". Prior to that, the user should copy the existing Text/EBCDIC header by opening it with any text editor. This copied text/EBCDIC header information should be pasted inside the Text header from buffer window.
Now add or edit the text/EBCDIC header information within the Text header from buffer window and click OK.
After editing/adding additional information, execute the module EBCDIC editor module and check the Text header vista item.
Set text header from buffer - This allows the user to add/edit text header information. The user must copy the previous text header information and paste it inside the pop-up window. Once it is pasted, now edit the text inside the pop-up window. Now execute the EBCDIC editor module to see the changes by generating the vista items.
Clear text header from buffer - this option allows the user to clear the previously copied text header in the pop-up window.
