Data path pattern#

Users can define HDF5 data path from patterns. Patterns can contains one or several keyword that will be resolved automatically.

Existing keywords are:

  • {detector}: if provided then a detector dataset (or group) will be search from the upstream path.

    • constraint: must be at the end of the pattern

    • use cases: scan concatenation and HDF5 scan selection

  • {scan}: ‘wildcard’ for first entry of a HDF5 file.

    • constraint: must be at the beginning of the pattern

  • {first_scan}: pick the first entry of a HDF5 file

    • constraint: must be at the beginning of the pattern

    • note: was not sure if this is a good idea / helping the user. Anyway this is cost-less to have. If unused we will remove it.

  • {last_scan}: pick the last entry of a HDF5 file

    • constraint: must be at the beginning of the pattern

    • note: was not sure if this is a good idea / helping the user. Anyway this is cost-less to have. If unused we will remove it.
