We only provide imaging parameters for data collection* sessions.
A file called "METADATA_INFO.txt" contains all relevant parameters including Cs value, accelerating voltage, pixel size, exposure dose, etc. This file is automatically created within 30 minutes of the session data appearing on PNCC compute resources. Open the "METADATA_INFO.txt" file with any text editing program. Please contact the Data Team if the file can not be found for some reason in your data directory.
Keep in mind, that the pixel size value is coming from the cross-grating grid and can be a few % off. Contact your SPOC before processing the data to get an accurate value (calibrated on the standard protein dataset). The metadata file can be found at the same directory level where you will find the "frames/" folder and the "relion3_preprocess/" folders containing your raw images and preprocessed data.
*Note, the metadata file is not created for screening sessions.
