scicat_dataset_ingestor -c ~/.scingestor.yaml

Its configuration written in YAML can contain the following variables scicat_url, ingestor_credential_file, beamtime_dirs or beamtime_base_dir e.g.

beamtime_dirs:
  - /home/jkotan/gpfs/current
  - /home/jkotan/gpfs/commissioning
scicat_url: http://localhost:8881
ingestor_credential_file: /home/jkotan/gpfs/pwd

scicat_dataset_ingest

Re-ingestion script for SciCat RawDatasets and OrigDatablocks is usually performed at the end of the beamtime.

scicat_dataset_ingest -c ~/.scingestor.yaml

Its configuration written YAML like for scicat_dataset_ingestor
