.Note: To program a broken probe we must know the
full identifier printed on the probe
and theoption
number. The serial number is essentially arbitrary. It is useful for communicating problems to Imec, and for your experiment metadata. Using "the wrong" 9 digits will not affect the probe or experiment outcomes.
Probes have a tiny EEPROM chip (circled in red
) containing the probe serial number, option, and ADC/gain calibration data.
EEPROM
If the chip detaches or breaks then SpikeGLX displays the following probe info when you click the 'Detect' button in the Devices tab:
Note that true serial numbers never start with '1' and are only 9 digits long, whereas the bogus serial numbers usually start with '1' and are often longer.
Although there are real option 4 probes, a broken EEPROM always presents as option 4.
The probe can still be used through a manual override feature. First ask the manufacturer for the calibration file set matching the probe's printed (nominally 11-digit) identifier. Then follow the instructions below to command SpikeGLX to use the files instead of the EEPROM chip.
Note: You will have to revisit the 'Force' dialog for this probe each time you quit and relaunch SpikeGLX.
A probe's data folder looks like this:
15039707141\
Comparator calibration.csv
Gain correction.csv
Offset calibration.csv
Slope calibration.csv
If you need to access a broken probe, get its data folder and drag it into subfolder SpikeGLX/ImecProbeData
.
If you don't see the ImecProbeData
subfolder, create it yourself with exactly that case and spelling.
Click Detect
on the Devices
tab when you want to:
Click Same As Last Time
to keep current flag settings for the next run.
Click Force...
on the IM Setup
tab to access data override features:
Label: Enter the (nominally 11-digit) code printed on the probe, or click Explore ImecProbeData
to copy it from the probe's folder so you can paste it into the box.
Serial #: Enter the 9-digit serial number directly, or click Take 9 From Label
to create a 9-digit number based on the label.
Option: Remember to select the appropriate option number for this probe. This is not derived from the label as of 4/30/2018.
This is not recommended, but available in cases where the probe data files are corrupt or you just don't have them and still want to use your broken probe.
