Key points for the .csv file format

• The first column in the .csv file is the time column

  • The time column can only carry unique values

  • The values in the time column do not need to be consecutive

  • The time column can have non-uniform timesteps.

  • The time column does not need to be sorted. Hysopt will do sorting at the start of the simulation.

  • All cells between the top time value and bottom time value need to be filled in and thus cannot remain empty.

• The datafile matrix cannot contain any empty cells. For each variable, every timestep requires a value.

• Ensure that non-existing columns are effectively empty. Verify this by opening the .csv with e.g. Notepad
