each channel icon. Not sure why it still read 'RAILED'. I only used 1st channel. What do you think about 0kOhm reading in the screenshot?

You can definitely include ILF/ISF (infra low frequency / infra slow fluctuations) in your work, as did some of the research cited in that thread. However I'm not clear on the source of your RAILED co

* I have two RAILED channels at nodes O1 and O2. They map to channel 7 and 8 on the GUI. I've tried adjusting the headset to make better contact but that didn't work. Any suggestions for how to fix th

I run experiments with Cyton alone and this time channels weren't railed.

Let's forget about the Daisy, and just stick to the mainboard with 8 channels, until we figure this out the RAILED issue.

But with the correct configuration I just got all channels railed

But when the Daisy is connected some channels are railed, even if they weren't railed while Daisy was disconnected:

I run some experiments and noticed that when Daisy connected to Cyton - all channels are railed, but when Daisy is disconnected the amplitude is huge. I added the video, maybe it'll give you some more

I took a quick look at the videos. Hmm, none of these seem to show the headset actually on your head. Without the scalp connection, of course everything looks railed. And just touching the pins is a v

After assembling Mark IV headset with Cyton & Daisy according to the instructions, I found out that amplitudes were higher that expected, also a lot of channels were RAILED when I 100% sure th

@wjcroft Channels 2, 4, 6, and 7 are railed when I playback at least two of the files above. The other channels look ok.

Generally RAILED condition can be other factors. You don't need to induce pain to get lowest possible impedance. Please re-examine Richard's @retiutut 's numbers.

And > 2000 - 3000 kOhm is not appropriate because the OpenBCI GUI often displays RAILED when the impedance is high, that means the electrodes don't contact skin.

Hello ! Still fighting.. What exactly means the RAILED message ? Why I see (randomly) channels going to RAILED while no signal is applied?

The range of the impedance remains essentialy the same. Yet the signal did some funny things link being railed at the start of the recording on most channels then turning okay, not stoping the impedan

Those spikes look like "low battery" spikes to me. Also, channels 1 and 2 aren't railed.
