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
