Density values in voxi unusual
Dear Voxi user I am new user in Voxi earth modeling and have some questions about it. I have gravity data for inversion. I only have topo data to be used for sensor elevation as well as DEM grid, am I right? Normal unconstraint inversion give me voxel file (V1) with data values as -46 to 23.7. Is that normal density or…

I am making a best effort to utilize the IP extension...but having some difficulties.
Admittedly I am dealing with time-domain IP data which I normally avoid. What I don't understand is what precisely is in the array channel? I am importing gdd data with 20 gates on the decay. The channels are noted to be IP and IP_average. So what is this IP? I want chargeability which is an integral or for digital data is…

Rotating MVI vector voxels
Hi, Does anyone have a workflow for Rotating MVI voxels. I can think of one but wondering if anyone knows a better way. VOXI inversions run faster if the X axis is smaller than the Y. So it is wise to rotate your data before inversion. I do this by rotating the X and Y coords in the gdb (Coordinates>Rotate) CCW about a…

Georeference an Image
I have control point on a png image and I want to georeferenced it in UTM. I know the coordinates in UTM of the control points. I don't find the help instructions clear for the warp tool under coordinates\georeferenced. 1) I don't really want to warp it so I don't understand identify a new and old point, 2) I can't see…

Voxel Math
Hi, I am trying to write some python code to do the following. 1) Open a geosurface file 2) Iterate through the surfaces in the file a) extract the extents of the surface b) create a voxel covering the extents, all value = zeros c) use voxel math to change all cells inside the surface to 1 and outside to DUMMY d) save the…

Creating an executable file from a Python script
Hi, I wrote a Python script to calculate the time decay constant for time-domain EM data, and it works well. But when I build an executable file from the Python script using cx_Freeze, I can't run the program. I get an Python error of "File NotFoundError" (attached image) caused by a file named…

how to make 2D line plot with vary value depend on the third value
Hi all, I have a X, Y, D file, X, Y is the lat and lot, D is the third value. I'm trying to plot the 2d line with the varying color depends on the value of Z (e.g. see the attached picture), could anyone suggest a good way to do this in Geosoft? I'm hoping to add the line plot to my existing Geosoft map. Thank you!

Licence Recovery and Installation procedure
I have licenced Gosoft version 8.3 installed in our PC having windows8.1 operating system. Now we have purchsed new system having OS windows10 and we want to change the Gosoft software to our new pc. But we lost the original purchased CD. So how we can transfer geosoft into new system.

Hardware questions on new build specifically for this software GPU/CPU/RAM etc. great budget
Trying to select the best hardware for a build specifically for this software. Not a gaming rig. If I am going to select GPU computing will a tesla or quadro series GPU be overkill? Is a single 1080ti more than enough? Go Dual 1080ti? Would it be better to get the new AMD threaddripper 32 core 64 thread 3.0 w/ boost 4.2ghz…

how to make a rectangular map of polar region
Hi all, I'm wondering how to make a rectangular map of Antarctica region with Lat and Lon labeled. When I first created the Map, I used the Lat and Lon limit to define the specific region that I'm interested in Antarctica, but it will give me a conic shape of map. If I created the map by defining the X and Y limit (from…

How to turn off floating windows - New to 9.2
Have you tried using floating windows in Geosoft? Instead of stretching the main Oasis montaj window across multiple monitors, you can drag just your map, database, or grid onto a second monitor. While I love this floating document feature when I'm working with multiple monitors, sometimes I am only working on my laptop…

depth-to sources methods: tilt angle and Euler deconvolution
Hello everyone please I am a beginner on Geosoft. I have used a satellite gravity data whose resolution is 5000m (2.5 arc minutes). I have three questions: 1. Considering a flying height of 5000 m and a suitable structural index, will the results from the Euler method give me solution depths below ground surface? 2. Are…

3D SEG-Y using external "Nav" file?
I am wondering if anyone who works with 3D SEG-Y volumes has encountered volumes "in the wild" that get their X,Y trace coordinates from an external "Nav" file? In all of the cases I've seen, either * The text header or a "load sheet" ties 3 or 4 Inline/Xline coordinates to actual X,Y coordinates, * the trace headers have…

Get and change map object colormap to custom one through GX
Hi. Since changing colormaps(for example for comparative profiles) is a chore in Geosoft, I am scripting a GX to do it. Changing one colormap that is not in the standard folder and a zone file is about... 15 clicks? More? Anyway. Pretty much first GX. I got a list of my maps and I filtered it for the ones I need def…
