These files are used to list the grid models and weighting factors to be run through the multivariate anomaly analysis (RockWorks | Utilities | Grid | Statistics | Multivariate Anomalies). They have a very simple format.
Example
Column Summary
- Grid Name: List in this column the names of the grid models to be processed. They must reside in the current project folder.
- Weight: Enter here for each grid model the amount it should be weighted in the anomaly analysis. A weight of “1? is default if no weighting is entered. The weighting value will be multiplied to the standardized grid node values during analysis (so a grid model weighted at “2? will have twice the influence of a grid model weighted “1? in the output model).
! All of the GRD models must have the same dimensions and node spacing in order for the program to be able to perform the grid analysis.
