Error in electrodes number during recording

[Sophie.ar]

Hello,
We have accidentally run with a 128-channel with extra-electrodes (EXG1 => EXG8, GSR1, GSR2, Erg1, Erg2, Resp, Plet, Temp).
The resulting .bdf contains too many channels. I tried to use ActiTools to fix this error by using the Reducer mode and then Converter. The extra channels disappear from my .bdf but I can't run it on my stat software. The message displayed is uncii 128 code error. I also tried to use Reducer and then Cropper to modify the excess electrodes by hand with a wordpad, without success either!
Does anyone have a solution to my problem?
Thanks a lot
Sophie

Use just the Reducer. Do not use the Converter (converts 24-bit BDF to 16-bit EDF).
