General options

The following entries appear in all parameter files

Number of realizations

The number of realizations to generate

Random Seed

An integer determines the random seed. A fixed value will return the same realizations for each run.

[0] assign a ‘random’ seed at each iteration (new seed every second)

Simulation grid size X, Y, Z

The number of grid cells in the simulation grid

Simulation grid origin X, Y, Z

The value coordinate of the first pixel in the X, Y, and Z direction.

Simulation grid grid cell size X

The size of each pixel in the simulation grid, in the X, Y, and Z direction.

Training image file

The name of the training image file (no spaces allowed).
it must be in GSLIB/EAS ASCII format, and the first line (the ‘title’)
must contain the
dimension of the training file as ‘NX NY NZ’.
See the TI folder for examples, and Training image
format for more information.

Output folder (spaces in name not allowed)

The path to the folder containing all output. Use forward slash ‘/’ to separate folders.

Shuffle Simulation Grid path (2: preferential, 1: random, 0: sequential) # 2

[0] sequential path through simulation grid (possibly a multiple grid)
[1] random path through simulation grid
[2] preferential path (only useful when soft data is considered)

Entropy factor

When a preferential path is selected the ‘EntropyFactor’ can be se as a second parameter after the choice of path.

Shuffle Training Image path (1 : random, 0 : sequential)

(Does not affect snesim type algorithms)

[0] sequential path
[1] random path

HardData filename

EAS filename with 4 columns: X, Y, Z, and D

HardData search radius

(world units)

Softdata categories

(separated by ;)

Soft datafilenames

(separated by ; only need (number_categories - 1) grids)

Number of threads (minimum 1, maximum 8 - depend on your CPU)

Currently not used.

Debug mode

[-2]: No information is written to screen or files on disk
[-1]: + Simulation output is written to files on disk
[ 0]: + Information about simulation is written to screen
[ 1]: + Simulated realization(s) are shown in terminal
[ 2]: + Extra information is written to disk (Random path, number of conditional data, …)
[ 3]: + Debug information written to screen (results in much slower performance - in general not useful for an end-user)

MASK file

EAS filename with 4 columns: X, Y, Z, and MASK. A mask files of tha same size as the simulation grid can be supplied. ‘0’ in a node indicates a node that will not be simulated. ‘1’ in a node indicates a node that will be simulated.

Entropy

[ 0]: No computation of entropy
[ 1]: Compute entropy/self-information as part of simulation

See [HANSEN2020] for more information.

Estimation

[ 0]: Do not perform sequential estimation
[ 1]: Perform sequential estimation (rather than sequential simulation)

See [JOHANNSSON2021] for more information.
