When we connected to all the bottom channel only for the cyton we were getting the channel railed for some reason that is why we didn't consider it previously now that the impedance is ranging from 60

thank you very much for your response. Of course, I have already completed the "getting derailed" steps and also tried different filters, hardware settings, and locations. In my opinion, it

All signals are railed, although the impedance test is confirming low resistivity.

I don’t have a screenshot, but yes—this means that channels 9–16 (right ear) are showing flat/railed signals (0 µV). Also, the file size is only about half of a successful recording. For example, a su

Best subjective measure is just to confirm that EEG is in 'normal' range. Below 100uV, not railed, no unusual patterns in the FFT, etc.

the channels, the signal quality shows "not railed", and in the range 50uv, meaning a good signal.

Ideal “not-railed” signals: what exact settings do you recommend when signals are not railed?

Despite correct placement and consistently excellent impedance values (typically 4–10 kΩ across channels), the EEG signal is almost always flagged as “Near Railed” or “Railed,” with rail percentages f

to begin displaying good signal and have a 'Not Railed' value for much longer (sometimes not becoming Railed at all).

1. Poor electrode contact - did you have signals on all channels? Or were several RAILED?

for a long period of time the channels get railed and could not make them not railed. what will be the problem. i have replaced snap electrodes and wires too, but the problem remains.

Thanks for sending it over. When I changed the BIAS and SRB wires from it being attached on the bottom to the top of the cyton board, then all of the electrodes starts showing not railed as I want it.

The issue is that on the OpenBCI GUI, I always see a message near the graph saying 'Not Railed' or 'Near Railed'. I am confident that the electrodes are making contact with my head, but on the Cyton D

I have had this issue for a few months now, and after I put the headset on, the signals say that they are railed. I did the recommended things to fix this (check connections, make the electrode tight
