Processing Errors

Top  Previous  Next

As COMPASS processes a survey file, it can encounter several different kinds of errors. Some errors are simple and the program can continue to process data without stopping. Other errors, particularly errors that result from a corrupted file format cause the program to abort processing.


The Error Log. All errors are saved to an Error Log. The Error Log saves all errors generated during a session, no matter how many files have been processed. The error log appears at the bottom of the Project Manager window and is automatically displayed when data is processed. You can also display the Error Log by pressing the “Show/Hide Error Window” option on the Tool Bar or selecting the "View|Error Log" option from the menu bar.


All error messages are prefaced with the file they occurred in. This way it is easy to tell which file caused the problem. Depending on how a project is linked, some files may get processed more than once and so their names may appear in the error log more than once. Here is a list of the known error messages:


1. Shots With No Tie In.

2. Disk Error.

3. Out Of Memory.

4. User Abort.

5. Zero Length Loop.

6. Un-closable Loop.

7. Unable To Open.

8. Windows Errors.

9. Program Bugs.

10. Linking Station Not Found.
