Simultaneous EEG + EMG

Hi all,

I am hoping to run an experiment that records EEG and EMG from the hand/arm muscle through the EX channels. For the hand muscle, we would use two of the EX channels but if we were to use a separate CMS/DRL set with flat-type electrodes connected to the AD-box front-panel, would that ...

Re: Trouble with repairing BDF file

Hi Coen,

Thank you so much; I couldn't load the BDF file on MNE before but it can be loaded now. However, there now seems to be an issue with the trigger codes. I always record in decimal mode with the trigger codes 251 (525 trials), 252 (525 trials), 253 (525 trials), and 53 (100 trials) for a ...

Re: Trouble with repairing BDF file

Hi Coen,

Thank you for the quick reply. I've attached the error message. It is definitely from ActiView, though, because I have 30 other BDF files also collected with ActiView, with the same configuration and setup, and I haven't experienced any issue processing them through MNE.

Thanks,
Nathan

Trouble with repairing BDF file

Hi all,

I am having an issue loading two BDF files into MNE-Python, which I suspect to be an issue with the header. Based on reading some of the threads here, I tried to use ActiTools to repair the BDF files. For the first one says 'Completed successfully' but the fields remain blank and the ...

Strange Signal Drift

Hi everyone,

Just discovered this forum a few days ago and I've learnt a lot while browsing it. Thank you to all who've asked questions and taken the time to answer them! Recently, I was recording EEG and noticed this strange drifting in the EEG signal. I've seen this before but I have no idea what ...
