Troubleshooting
No SpikerBox or no live signal
- Check power and use a USB data cable.
- Close other apps or browser tabs that may be using the device.
- Choose SpikerBox → Connect. If several devices appear, choose the correct one.
- In the browser, select the device and allow access in its chooser. A Chromebook needs this permission before recording over USB.
- Confirm that channels are enabled and follow the electrode/setup checks in your device's guide.
If the browser offers no device chooser, use a browser with Web Serial support for USB recording. On a managed Chromebook, check device-access policy with the administrator. See Connect a SpikerBox.
The trace is moving, but there is no recording
A live trace alone is not a recording. Press Record and look for Stop and the recording clock. Finish with Stop and complete the save step.
Record says “Connect a SpikerBox to record”
There is no connected live device. An opened recording is for playback and analysis. Use SpikerBox → Connect to switch to a live source.
Buttons disappeared or do not respond while recording
Recording limits the available controls. Use Stop, finish saving, and then change channels, open a file, or use the analysis tools.
The live trace froze
Check whether live acquisition is paused. Press Play to resume at the current live signal. Samples arriving during a live pause are not kept. Also check the cable and connection if resuming does not restore the trace.
I cannot find the saved file
- Browser: check the chosen destination and Downloads. Canceling the save dialog did not save the recording.
- Desktop: use the location in the app's saved message; it may differ from the usual Documents folder.
- Phone/tablet: press File to open the app's recordings list.
A save error means you still need a successful save. See Files and sharing.
I added an event, but it is missing after reopening
For an opened file, use the disk-shaped Save button after editing and complete the save prompt. Open the copy you actually saved, especially if you changed the name or the browser downloaded another copy.
Events shows no average
Check that you have selected spikes in Detect or placed event marks, that the intended channel is on, and that the selected entry has contributing events. A threshold that misses the signal will not provide spikes to average.
The signal is noisy or too small
Check electrode contact, the device's setup, the selected channel, and the displayed amplitude scale. Review channel preparation/filter settings. Changing the visual scale makes the trace larger or smaller on screen; it does not repair the source signal.
Ask for help
Email [email protected] with your SpikerBox model, app version from SpikerBox → Settings, OS/browser version, the action you tried, and the exact error. A screenshot and a short example recording, when you can share one, help explain the problem.
