8. Troubleshooting

Questions, feature requests, and bugs: please open a github issue. Kindly provide the error output, describe what you are attempting to do, and attach the DZT/DZX/DZG file(s) causing you trouble.

If you have a question that involves sensitive or proprietary data, send me an email confidentially at ian dot nesbitt at g mail dot com.

Thanks for reporting errors and helping to keep scientific software free and open-source!

8.1. Filtering errors

The filtering algorithm readgssi.filtering.triangular() will fail if you use scipy 1.2.x. Please upgrade scipy to 1.3.0 to avoid errors while filtering.

8.2. Antenna code errors

Of all the errors you are likely to encounter, these are the most numerous, easiest to fix, and hardest to predict. GSSI is liberal when it comes to naming antennas, so antenna codes, which are the primary identifying feature of the center frequency of the antenna, are numerous. This wouldn’t be such an issue if GSSI had a list of them somewhere.

Alas, they don’t, so I’ve had to try to compile my own, and it’s incomplete. If you come across a KeyError in readgssi.dzt.readdzt() related to a variable called ANT, chances are your antenna needs to be added to the list. Copy and paste the error message into a new github issue and attach the DZT file to the message. I’ll try to respond within 24 hours.

If you want to modify the code yourself, have a look at the ANT dictionary in readgssi.config. Use the key from the error message to create a new entry in the ANT dictionary that has both your key and the frequency of the antenna you’re using. Once you’ve added the line with your antenna code and the frequency, reinstall and test your modified version of readgssi by Installing from source.

If your modified code is in a folder in your home directory, you should be able to reinstall using the command pip install ~/readgssi.

If you’ve tested it and it’s working, please create a pull request with the changes, or open an issue and describe the changes you made.

The dictionary of antenna codes and center frequencies as of May 04, 2021 (version 0.0.19) is below.
