General Troubleshooting
Software not discovering device
Unplug the device from your computer and re-plug it in. Try refreshing devices.
Ensure that you are using the USB cord which came with the cerillo device. At the very least, it must be a USB-2.0 cord, not USB-3.x.
Double-check that the cord is plugged all the way in at both ends.
Verify that the cerillo device boots completely; after plugging it in, its status light should turn white and then off (or a dim blue).
Check that the cerillo device appears as a USB device on your computer. On Windows, this can be checked by opening the Device Manager application, navigating to the Ports section, unplugging the Cerillo device, noting which COM Port disappeared, reconnecting the device and double checking the COM port name that appeared when reconnecting the Cerillo device.
If there is no corresponding COM port for your cerillo device, and none of the troubleshooting steps resolved the issue, you should send the labrador log file to Cerillo support. To do so, click the Help menu in labrador, then click View Log File. Save this file and send it to support@cerillo.bio for further troubleshooting.
Experiment results not showing up
Navigate to the experiment from your device’s experiment list or from results. “Right-click” on the refresh button to force refresh the experiment.
Check if the data is saved on the SD card on your device by removing power from the device, removing the SD card and plugging it into your computer with an adapter if necessary.
If the experiment files and all their expected data are on the SD card, but not in labrador when you “Right-click” refresh, contact support@cerillo.bio with subject line “Experiment results not showing up in Labrador, but present on SD Card” or something similar. Please attach the labrador log file which can be retrieved by clicking the Help menu in labrador, then clicking View Log File. Save this file and attach it to the email to support.
If the data is not on the SD card, follow the troubleshooting instructions for ‘Data Issues’ in your plate reader’s manual. That info can be found here if you do not have your plate reader manual.
Lastly, and most infrequently, there’s a potential that the experiment cache has been corrupted which might break retrieving experiments. To clear the cache, go to the Help menu and select Clear Cache Data
Warning
Clearing the Labrador cache will remove cached plate templates and experiments. It should only be done if all the experiment and plate layout data you need is saved in files. Clearing the cache should only be done as a last resort.
Note
It’s possible the experiment was deleted off of the SD card manually from a computer, in which case Labrador won’t be able to open the experiment.
Device doesn’t list any experiments or Device doesn’t record data to SD card or Device doesn’t show correct settings/name
Ensure the SD card is properly seated in the device. If the SD card was removed during device operation, the device will need to be rebooted by unplugging and re-plugging the power cord before it can write experiments to the SD card.
I made changes to my plate layout after the experiment started but now they aren’t showing up, what gives?
Plate layout information entered on experiment setup is saved on the device itself. However, any changes made to the plate layout made AFTER the experiment has started will only propagate on the computer where the change was made. If the device is connected to a different computer, the original plate layout entered here will be displayed in experiment results, regardless of changes made on separate computers. You might also not see changes made if you have cleared the application cache in the help menu recently as this would delete any user changes to plate layout information anywhere besides the Plate Layout inputs.
My canopy isn’t finding any devices
First check that you are signed in and have an active labrador premium license. Next, try unplugging the canopy and replugging it to your computer and then refreshing devices. Ensure that the cerillo device (probably a stratus) you’re attempting to connect to has the latest firmware on it by plugging it into a computer running labrador and refreshing devices. If that does not work, see if there is a source of electromagnetic interference within a meter of the canopy. Examples of device include wifi routers and bluetooth dongles. Moving the canopy away from such devices could improve connection reliability. Read Canopy Networking 101 for more information on how the canopy forms its network. If none of the aforementioned steps fix the issue, the device may be out-of-reach of the canopy.
Labrador is showing just a white screen, what do I do?
Unfortunately, Labrador is not 100% free of bugs despite our best efforts. You’ve just experienced a crash in the user interface. Restart the app and you should be able to resume using the app as normal.
License is not showing in user info dialog
If a user recently purchased a license for their organization and the license is not showing up in the User Info Dialog, that user can log out and log back in to refresh the license to the newly-purchased one.
