This is a file with an assessment of each subbasin's performance, or each output region if regional output variables are used. The file is located in the resultdir folder. One file is printed for each unique combination of simulated and recorded variable among the performance criterion included in the objective function given in info.txt. X is the ordinal number of the performance criterion and the subbasin assessment is calculated for the same variables as that performace criterion. If more than nine criteria are included, the following are denoted by capital letters. Definitions of equations for calculating the criteria is found here. Settings in info.txt decide which performance criteria is written.

When ensemble or sequence simulations are made, the results from simulations (I=1 .. n or I=sequence number>0) are written to files named subassX_00I.txt. For a Monte Carlo calibration n is defined by num_ens in optpar.txt. For a DE calibration n is num_ngen plus one, where the first one is a simulation with median of the others parameter values.

For the calculation of criterion for lake water stage, the combination of variables wcom and wstr are exchanged for the internal variables clwc and clws by the program. These variables are the water stages cleaned from w0ref reference level (clwc=wcom-w0ref, clws=wstr-w0ref). This makes the criterion calculation more accurate, but note that relative criteria, e.g. relative bias, are relative to the smaller cleaned water stage level.

The first row of the file let you know the average period (0=timesteply, 1=daily, 2=weekly, 3=monthly, 4=yearly) used for calculation of the values that are compared in the criteria. This period corresponds to the setting meanperiod in info.txt. Variable names and unit of the variables are also listed on row one. The second row is column headings. Thereafter follow subbasins which has observations, one on each row. The data limitation for calculating the subbasin criteria is the same as that of the calibration criteria. This limitation is not used for calculation of minimum and maximum values though. Missing values are indicated as -9999. Note: minimum and maximum values are based on the average period, e.g. maximum of monthly average flows.
