First, install the requirements (preferably in a virtual environment):
python3 -m venv virtual-env
Then,
source virtual-env/bin/activate
Finally:
pip install -r requirements.txt
To read the data and export to csv, type:
python3 ut_8channels.py <filename>
Just replace <filename> with the name of the file you want to export (don't forget to add the .utd suffix).
The output is a xlsx file with 8 sheets (each for a sensor). In each sheet, each column represents the data of a single A-scan.
