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

  1. Navigate to the experiment from your device’s experiment list or from results. “Right-click” on the refresh button to force refresh the experiment.

  2. 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.

    1. 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.

    2. If the data is not on the SD card, follow the troubleshooting instructions for ‘Data Issues’ in your plate reader’s manual.

  3. 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 license. Next, try unplugging the canopy and replugging it to your computer and then refreshing devices. Ensure that the cerillo device 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. 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.

Data issues or missing files

Primary causes:

  1. The device is powered on without the microSD card, or the microSD card was removed and reinserted while the device remained powered on. If the device is plugged in when the microSD card is placed inside, it will not recognize the microSD card and cannot record data to it. To solve this issue, ensure that the Cerillo plate reader is unplugged whenever the microSD card is inserted in the device. If the device is already on, it will not recognize the microSD card. If the device is powered on without an SD card, the device will have a red status light.

  2. An incompatible microSD card is used. Only use the supplied microSD card. If a replacement card is needed, be sure to format to FAT32 prior to using and only use cards under 32 GB capacity.

  3. Corruption of the microSD card (data is unreadable). To solve this, try formatting the microSD card using the instructions below.

Format microSD card on Windows

  1. Insert the microSD card directly into your computer, or use an adapter if your computer does not have a microSD card slot

  2. Copy any data off of the microSD card that you would like to keep

  3. Open File Explorer

  4. Right-click on the microSD card drive, select Format

  5. A formatting window will pop up. Under the file system drop down, select FAT32

  6. Uncheck perform a quick format

  7. Select OK

Format the microSD card on macOS:

  1. Insert the microSD card directly into your computer, or use an adapter if your computer does not have a microSD card slot

  2. Save any data on the microSD card that you would like to keep

  3. Open Disk Utility. It is available through the Applications Folder in a Utilities subfolder. You can also use Spotlight search to open it by name

  4. In the sidebar of Disk Utility, search for your memory card and select the volume. Typically you’ll find it under the name of the manufacturer of the memory card, and it will have a volume title that matches the name of the drive when it mounts, as well as matching capacity

  5. After selecting the correct volume, click Erase

  6. Enter a name for the memory card

  7. Select the format for the memory card as FAT32

  8. Click Erase

  9. Once formatting has completed, click Done
