bfit 1.3.1

BNMR/BNQR Data Fitting and Visualization

bfit

Beta-NMR GUI for reading, drawing, fitting data.

Run Instructions

To run, call python3 -m bfit

Setup after Install

Install is done simply by pip install bfit. Afterwards, 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.
