ALPHA SOFTWARE. This package is currently in its early stages of iteration. It may change both its internals or its user-facing API in the near future. Any feedback and ideas on how to improve either of these is more than welcome!

For more information on how to help, see CONTRIBUTING.md.

Installation

• install dependencies: pip install numpy
• install pybv: pip install -U pybv

Usage

from pybv import write_brainvision

# data: an ndarray of shape (n_channels, n_times)
# sfreq: the sampling frequency
# ch_names: a list of strings for channel names
# fname: the base file name for all created BrainVision files
# tmpdir: a path to where the output files will be placed
# events: an ndarray of shape (n_events, 2). Each row is an event,
#         the first column is the index of the event,
#         the second column is the event ID.
# resolution: the desired resolution (in volts) of the stored data.
write_brainvision(data, sfreq, ch_names, fname, tmpdir, events,
                  resolution=1e-6)

Acknowledgements

This package was originally adapted from palday's Philistine package. It copies much of the BrainVision exporting code, removes the dependence on MNE, and focuses the code around BrainVision I/O.
