| CryoNAV captures and manages two complementary streams of metadata: acquisition metadata extracted from microscope output files during import, and processing metadata generated during the platform's own pipeline runs.
| | #REDIRECT [[CryoNAV Metadata Management]] |
| | |
| == Acquisition metadata ==
| |
| | |
| For each tilt series, CryoNAV stores:
| |
| | |
| * Voltage, pixel size, dose rate, camera type
| |
| * Tilt range and per-tilt angles
| |
| * Acquisition timestamps
| |
| * Stage coordinates (used for [[Grid Visualization#Search map overlay|search map overlay]] placement)
| |
| * Search map and grid associations
| |
| | |
| This metadata is extracted automatically during [[Tilt Series Data Import|SmartScan import]] from .mdoc files and BatchPositionsList.xml.
| |
| | |
| == Processing provenance ==
| |
| | |
| Every pipeline step's parameters are stored as individual typed fields in the database, and the complete command-line invocations are recorded. Small intermediate files (tilt angles, alignment transforms, .mdoc contents) are stored directly in the database.
| |
| | |
| This design ensures that:
| |
| | |
| * The full processing provenance is captured.
| |
| * Results can in principle be reproduced from raw data and the database record alone, even if intermediate files on disk are deleted.
| |
| * Methods sections can be reported with accurate parameter values.
| |
| | |
| See [[Data Storage & Backup]] for how this enables selective intermediate-file cleanup, and [[Key Concepts#Immutable processing branches|Immutable processing branches]] for how parameter changes are recorded as new branches.
| |
| | |
| == Filtering and batch selection ==
| |
| | |
| Stored metadata is queryable throughout the interface. Filter expressions can combine acquisition values and user-assigned ratings/tags (see [[Sample & Experiment Mgt.#Rating and tagging tilt series|rating and tagging]]) for batch selection of tilt series.
