RockWorks | ModOps | Solid | Statistics | Standardize
Use this program to convert all of the non-null node (G) values within a block (solid) model such that new G-values represent the number of standard-deviations from the mean value. The result is an anomaly model.
In the above graphic, we've used this terminology: Slightly Anomalous is > 1 (Mean +/- 1 Standard Deviation), Moderately Anomalous is > 2 (Mean +/- 2 Standard Deviations), Strongly Anomalous is > 3 (Mean +/- 3 Standard Deviations), Extremely (aka Outrageously, Insanely, X-Treme) Anomalous is > 4 (Mean +/- 4 Standard Deviations).
! This program requires that the solid model being standardized already exists.
See also the Normalize program which converts solid model node values to a new, normalized value range.

Step-by-Step Summary
- Input/Output Models:
- Input Model: Click to the right to browse for the name of the existing solid model file (.RwMod) to be processed.
- Output Model: Click to the right to type in the name to assign to the new solid model whose nodes will represent standard deviations from the mean.
- Options:
- Compute Absolute Values: Check this box if the negative standard deviations are to be stored as absolute values. This allows high and low anomalies (standard deviations) to be compared together. Leave this box unchecked to stored the original standard deviation values.
- Set Background Values to Zero: Check this box if the source-model values considered "background" are to be assigned a value of 0. Type into the prompt the real number value below which nodes are to be reclassified as zero.
Tip: Use the Solid | Statistics | Histogram to create a frequency histogram of the node values in the (source) input model, where you can view their distribution and statistics.
- 3D Solid Diagram
Insert a check here to display the output solid model as a 3D diagram.
Click this tab to set up the diagram options.
- Block Diagram
- Isosurface: Click in the Isosurface radio button to display the solid model as if enclosed in a "skin." This view will be smoother than a voxel display. (More info)
- Voxels: Click in the Voxels radio button to represent the solid model in the 3D display as color-coded voxels. You can choose to display either the Full Voxel, or just the Midpoint. Display of the midpoint only can significantly improve display time for huge models.
- Color Scheme: Choose the color scheme for the block model - automatic, table-based, etc. (More info)
- Isomesh: Check this box to plot a series of polylines that represent three-dimensional contours at a user-defined cutoff. Click this tab to establish the settings. (More info)
- Other 3D Solid Diagram Options: Use these checkboxes to append other layers to your 3D scene. (Summary)
- Striplogs: Append striplogs to your 3D scene. (More info)
- Points: Display the 3D control points in the diagram. (More info)
! Note: This option only applies to the data that is loaded into the current Datasheet. If the data is being loaded from an ASCII file, thereby bypassing the datasheet, the Control Points setting will have no effect (i.e. no control points will appear within the final diagram)
- Faults: Include 3D fault ribbons with this scene. (More info)
- Drape Image: Include an image in this 3D scene, draped over an existing grid surface. (More info)
- Float Image: Include an image in this 3D scene, floating at a specified elevation. (More info)
- Infrastructure: Display buildings, pipes, or other infrastructure with your 3D scene. (More info)
- Other 3D Files: Include other, existing, RockPlot3D ".Rw3D" files in this scene. (More info)
- Perimeter Cage Include a 3D reference cage around the solid diagram. (More info)
- Legends: Include one or more legends with the diagram.(More info)
- Output Options
- Save Output File: Check this to assign a name for the 3D scene in advance, rather than displaying it as Untitled.
- Automatic: Choose this option to have RockWorks assign the name automatically. It will use the name of the current program plus a numeric suffix, plus the ".Rw3D" file name extension.
- Manual: Choose this option to type in a name of your own for this RockPlot3D file.
- Display Output: Check this option to have the resulting scene displayed in RockPlot3D once it is created.
- Select the ModOps | Solid | Statistics | Standardize menu option.
- Enter the requested menu settings, described above.
- Click the Process button to continue.
The program will read the node values from the input model. It will determine the G value range of the nodes and calculate the mean and standard deviations. Each node value will be converted to its standard deviation, which will be saved under the output model name.
If you requested a diagram, the model will be displayed in a RockPlot3D tab in the Options window, using the requested display type.
