  • Take into account ODV variants for biology, flow cytometry and microlitters for checks and conversions ODV to ODV
  • ODV check: the primary variable must have at least one non null value

Bug corrections:

  • NetCDF SDN Format: all numeric types are allowed (not only doubles)
  • Conversion MedAtlas to ODV: use of default value defined in the current station header
  • ODV format: Depth is no more mandatory in timeseries that contain a parameter belonging to P02 ASLV
  • Conversion NetCDF to ODV : remove extra tabulation at the end of lines
  • Allow COREDIST also in cm (ULCM) as primary variable
  • MedAtlas check: detect an error if a value = default and the flag != 9
