BDF+ to EDF+ converter.

[Teuniz]

EDFbrowser 1.13 is available. It has a BDF(+) to EDF(+) converter.

This tool converts a BDF file to an EDF file. A BDF+ file will be converted to
EDF+, including the annotations/events.
It uses a first order highpass-filter to remove the DC-part of the signal in
order
to make the 24-bits samples fit into the 16-bits samples of EDF.
The cutoff-frequency of the highpass-filters can be adjusted for every signal.
You can also select which signals have to be converted into the new EDF(+)
file.
Increasing the divider lowers the resolution but increases the range (physical
maximum and minimum).

I recorded 128 channels + (2) EOG channels and GSR. I made a slight error in the settings when recording, so I ended up with 266 channels. I try to open them using EDF reader but it refuses to open the file because of the channel numbers exceed 256.

Can I get around this somehow?

Thanks

Delete the unused channels from the BDF file with the Reducer tool, download from http://www.biosemi.com/download/Reducer.zip
