dpest.utils.parg_inctyp

dpest.utils.parg_inctyp.parg_inctyp(pst_path, updates)

Updates INCTYP values for one or more parameter groups in a PEST control (.pst) file.

The INCTYP field specifies the increment type used by PEST for derivative calculations in the * parameter groups section. Typical values are relative and absolute. This function modifies the * parameter groups section of an existing .pst file in place.

Required Arguments:

• pst_path (str):

  Path to the .pst PEST control file to modify.

• updates (dict):

  Dictionary mapping parameter group names to new INCTYP values.

  Example:

  {
      "PART_SEED": "relative",
      "SEED_COMP": "absolute"
  }
  

Returns:

• None

The function updates the * parameter groups section in place.

Examples:

1. Update INCTYP for two parameter groups:

   from dpest.utils import parg_inctyp
   
   parg_inctyp(
       pst_path = "A-1_input/PEST_CONTROL.pst",
       updates = {
           "PART_SEED": "relative",
           "SEED_COMP": "relative"
       }
   )
   

2. Set one parameter group to absolute increments:

   from dpest.utils import parg_inctyp
   
   parg_inctyp(
       pst_path = "PEST_CONTROL.pst",
       updates = {
           "SEED_COMP": "absolute"
       }
   )
