Hi everyone,
I’m trying to find and export the uncalibrated OD data. I performed an OD calibration before the run, but the resulting curve doesn’t match my manually measured end-point OD. Since the curve shape of the uncalibrated looks good overall, I’d like to get access to this data.
Where can I find the uncalibrated OD values, and how can I export them after the run?
Thank you for your help 
Hi @ClaraF
During writing up a response to you, I realized there was a file that was missing in the shipped images that you need to access the uncalibrated OD readings. However, it’s easy to add that file after the fact.
SSH into your leader Pioreactor, and type:
nano ~/.pioreactor/exportable_datasets/27_raw_od_readings.yaml
and copy and paste the following:
dataset_name: raw_od_readings
default_order_by: timestamp
description: This dataset includes a time series of raw readings provided by the sensors
(that is, not transformed by a calibration curve).
display_name: Raw optical density (uncalibrated)
has_experiment: true
has_unit: true
source: app
table: raw_od_readings
timestamp_columns:
- timestamp
and ctrl-x to save and exit.
Now, visit the Export data page in the UI, and you should see a dataset named “Raw optical density (uncalibrated)” - these are what you are looking for!
Let me know if you encounter any issues.
Thank you for your help. It worked and I can export the raw data now
