Bug¶

Fixed a bug in private pybv._export module for export to BrainVision from MNE-Python, by Stefan Appelhoff: (#90)

0.7.0 (2022-05-28)¶

Changelog¶

Added an overview table of alternative software for BrainVision data, by Stefan Appelhoff (#85)
pybv.write_brainvision() now accepts a list of dict as argument to the events parameter, allowing for more control over what to write to .vmrk, by Stefan Appelhoff (#86)

0.6.0 (2021-09-29)¶

Changelog¶

pybv.write_brainvision() gained a new parameter, ref_ch_names, to specify the reference channels used during recording, by Richard Höchenberger and Stefan Appelhoff (#75)

API¶

pybv.write_brainvision() now has an overwrite parameter that defaults to False, by Stefan Appelhoff (#78)

Bug¶

Fix bug where pybv.write_brainvision() would write the binary file in big-endian on a big-endian system, by Aniket Pradhan, Clemens Brunner, and Stefan Appelhoff (#80)

0.5.0 (2021-01-03)¶

Changelog¶

pybv.write_brainvision() adds support for channels with non-volt units, by Adam Li (#66)
pybv.write_brainvision() automatically converts uV and μV (Greek μ) to µV (micro sign µ), by Adam Li (#66)

API¶

The unit parameter in pybv.write_brainvision() now accepts a list of units (one unit per channel), by Adam Li (#66)

0.4.0 (2020-11-08)¶

Changelog¶

Passing a “greek small letter mu” to the unit parameter in pybv.write_brainvision() instead of a “micro sign” is now permitted, because the former will be automatically convert to the latter, by Stefan Appelhoff (#47)

Bug¶

Fix bug where pybv.write_brainvision() did not properly deal with commas in channel names and non-numeric events, by Stefan Appelhoff (#53)
pybv.write_brainvision() now properly handles sampling frequencies that are not multiples of 10 (even floats), by Clemens Brunner (#59)
Fix bug where pybv.write_brainvision() would write a different resolution to the vhdr file than specified with the resolution parameter. Note that this did not affect the roundtrip accuracy of the written data, because of internal scaling of the data, by Stefan Appelhoff (#58)
Fix bug where values for the resolution parameter like 0.5, 0.123, 3.143 were not written with adequate decimal precision in pybv.write_brainvision(), by Stefan Appelhoff (#58)
Fix bug where pybv.write_brainvision() did not warn users that a particular combination of fmt, unit, and resolution can lead to broken data. For example high resolution µV data in int16 format. In such cases, an error is raised now, by Stefan Appelhoff (#62)

API¶

pybv.write_brainvision() now accepts keyword arguments only. Positional arguments are no longer allowed, by Stefan Appelhoff (#57)
In pybv.write_brainvision(), the scale_data parameter was removed from pybv.write_brainvision(), by Stefan Appelhoff (#58)
In pybv.write_brainvision(), the unit parameter no longer accepts an argument None to automatically determine a unit based on the resolution, by Stefan Appelhoff (#58)

0.3.0 (2020-04-02)¶

Changelog¶

Add unit parameter for exporting signals in a specific unit (V, mV, µV or uV, nV), by Clemens Brunner (#39)

API¶

The order of parameters in pybv.write_brainvision() has changed, by Clemens Brunner (#39)

0.2.0 (2019-08-26)¶

Changelog¶

Add option to disable writing a meas_date event (which is also the new default), by Clemens Brunner (#32)
