Exporting .hdr data from legacy format (.cu3). How to introduce calibration data?

[emmipel]

Hi all,

I'm having an issue exporting my measurement data. I'm not very well versed in Python or CUVIS, but I've been using the documentation and example data provided here on GitHub to learn more. I have some measurement data in legacy format (.cu3) and have been attempting to export the .hdr data (ENVI) using "Cuvis Python SDK Example 4" as a template. I have done some minor changes, such as changing "session = cuvis.SessionFile(session_file_path)" to "mesu = cuvis.Measurement(session_file_path)", but I believe my problem stems from missing calibration data, since to my understanding it is not stored in the .cu3 format (as opposed to .cu3s). I have not figured out a way to introduce the calibration data into the code, as of yet. Should I do changes to Calibration.py? Or should I use a certain command or function to add the data?

If anyone has a suggestion as to how to go about this issue, I thank you very much in advance!

Hello,

you are correct the legacy file format does not store the Calibration Information inside itself.
For the legacy file Format, the Calibration data is expected to be in a folder Calibration as a init_{some_hash}.daq in the folder next to the data (or some parent folder). In general this file structure should also have been written when the data was captured.

Also if you have the original init file that you used to capture the data you could manually create the Folder and place it there.
In the log file it should provide you with the filenames that it can't find.
