Setup
Dependencies needed pre-install
- Cython:
pip3 install --user Cython
- numpy:
pip3 install --user numpy
- Tkinter for python3:
sudo apt-get install python3-tk
(for example), - python version 3.6 or higher
Install instructions
pip3 install --user bfit
Optional seteup
You may want to tell bfit where the data is stored. This is done by defining environment variables
BNMR_ARCHIVE
and BNQR_ARCHIVE
(for convenience add this to your .bashrc script). The expected file format is as follows:
/path/
bnmr/
bnqr/
2017/
2018/
045123.msr
In this example, you would set BNQR_ARCHIVE=/path/bnqr/
to the directory containing the year directories.
If bfit cannot find the data, it will attempt to download the files from musr.ca according to the defaults set in the bdata package.
