New in Om5.1.8

Chimera Advances

Probability Analysis Tool: The interactive Probability Analysis Tool displays the selected channel, channel statistics, probability plot, current cursor position and corresponding data value and percentile values. The tool is a dynamic dialog box that updates data values whenever you make a change to a corresponding value in the database.

Multi-Probability plot: Use this GX to plot multi-probability graphs on a map.

Normalize Chimera Database: The CHNORM GX creates a new, normalized channel (the new channel adds "_N" to the selected channel name).

Standard and Duplicate report: Added the "Project Description" to the title block info for both the Standard and Duplicate reports in Chimera.

General Oasis montaj

Image orientation: The IMGORIENT3D GX enables you to set up or modify the orientation of a grid in 3D space.

Create section from array: There are 5 new GX’s dealing with arrays. These new GX’s enable the user to create section maps based on array channels.

Adding arrays: We have added the ability to add and subtract arrays using the math expressions in the database.

Rangrid: Added a distance weighting parameter that causes all data within one grid unit to be combined into one weighted location and z value. This can be used for the reduction of the high-frequency aliasing caused by gridding at too coarse an interval. The weighting slope parameter controls a bell function: weighting = 1 / (distance^wtpower + 1/slope) where distance is in units of grid cells. The default is 0.0, where only the nearest data effect grid nodes.

Krigrid: If a user selects the "Variogram Only" option while running KRIGRID, then the output variogram is automatically plotted to a new map "variogram.map", which is displayed to the user.

FFT1D

Hilbert Transform: The Hilbert Transform is a mathematical transform that shifts each frequency component of the instantaneous spectrum by 90 degrees without affecting the magnitude.

Fractional derivatives: Added support for fractional horizontal derivatives for the 1DFFT. The user can now produce fractional differentials of profiles.

Wholeplot

Select Holes- Selection Tool: Modified the drillhole Selection Tool from a single list to a 2-panel selection dialog.

Select Holes- by Area: Created an interactive drillhole Selection dialog that enables users to interactively select and deselect holes by polygonal area, rectangle and individual hole.

MAGMAP

Fractional derivatives: Added support for fractional horizontal derivatives for the 2DFFT. The user can now produce fractional differentials of grids.

Geosoft Plus Partners advances in Oasis montaj 5.1.8

GM-SYS 4.8.45b

GX Developer advances in Om5.1.8

New GX Debugger: The GX debugger invokes the source code of the selected GX in an interactive workspace at execution time, and enables the GX-developer to step through the GX a line at a time, and inspect the variables' content. The design of the GX debugger is loosely based on the Microsoft Visual Studio workspace; the GXC code is displayed in the main "edit" pane, the user has the option to introduce break points in the active code, as well as display variable values in the "watch" pane. The variable values can be changed at run time. In addition the user may step into secondary GX code called by the primary GX.
