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

with the battery pack that came with the cyton. Do you think that could be a problem? Maybe as a sidenote, even when I used the batteries for the first time, FP1 and FP2 were railed...

I keep having the problem that my FP1 and FP2 channels are railed in the GUI, eventhough I connected everything as described in the documents. When I toggle them, they are derailed for 10 seconds and

Please see this thread with suggestions on RAILED condition.

* The impedance of the target electrode sometimes goes very high ( > 5000 kOhm, or Railed ).

That was also the thread I found by searching for "RAILED": https://openbci.com/forum/index.php?p=/discussion/1481/how-to-become-de-railed

after a while, the signals get often "RAILED", I don't even have a cap connected (only the y-cable is attached):

I tried to touch the pins with my fingers to test the connection as the docs said but all channels still show noise and nothing in particular had changed. I also tried connecting the gold cup electrod

Here are some good background posts on 'railed', using the Advanced Search button in the upper right column:

Hi, i'm using an openBCI setup with a cyton + daisy module. My experiment in running in a separate program which also runs a driver for the openBCI. This works fine most of the time, but sometimes dat

3. The signal level of good beats is about 1500 uVrms, but can vary from 400 to 2600 and intermittently flashes 'Railed'. I don't see a lot of noise, nice clean beats but vary in strength quite a bit

I now understand the reason for the signals getting railed. Is there any suggestion on how can I solve this situation?

Railed means the signal is out of range.

I have been experimenting with making my own set of electrodes for EEG measurement. I prepared two set of electrodes with different set of materials. The first type of electrode is working fine and gi

As you've seen from the other 'RAILED' threads, RAILED just means that the current channel values exceed what can be shown at the current Time Series scale factor. Or if 'Auto' is selected, the channe

I found a post about changing the pins to the lower set instead of the upper ones. http://openbci.com/forum/index.php?p=/discussion/220/channels-stuck-at-railed

UPDATE - it's working now (kind of? it worked for 1 second then it just said RAILED for all channels). Vert Scale Auto. I tried toggling the Window and other settings. Accelerometer looks OK.

Depending on the noise in the environment, operating the Cyton with no leads connected to the pins can produce various types of 'RAILED' (maximums exceeded) results. The only sure way to assess a chan

All channels show the message: "Railed" so maybe using those earclips as reference could be the source of the problem as i´m not sure if they are compatible with the electro cap. (I am indee
