Python package which reads and parses xml data from LF in Motol.
The project is currently hosted on test PyPi and can be downloaded from such https://test.pypi.org/project/bvareader/
Main use can be through the command line prompts, which doesn't require you to run your own preprocessing scripts. But if you prefer, you can preprocess and save the data in your own way.
from bvareader.reader import read_positions
from bvareader.reader import read_sync_times
from bvareader.reader import read_sync_file
from bvareader.exporter import save_csv
from bvareader.preprocessing import prepare_positions
from bvareader.preprocessing import add_rotation
pd_bva = read_positions("example_data/example.xml")
pd_bva_clean = prepare_positions(pd_bva)
save_csv(pd_bva_clean, "bva.csv")
save_csv(pd_bva, "bva_full.csv")
bva_sync = read_sync_times("example_data/example.xml")
save_csv(pd_sync, "bva_sync.csv")
pd_sync = read_sync_file("example_data/example.csv")
save_csv(pd_sync, "sync.csv")Bva outputs real timestamp (date and time of each recording). This package converts this datetime number as the POSIX timestamp (number of seconds since 1.1.1970) as per datetime.timestamp() function described in here
By installing the package from PyPI, you will get the python entry point which you can use in the command line. You can investigate each command with the --help tag. e.g. process-bva --help. Mostly you will need only the process-bva and potentially xml-settings-to-csv commands
