Looking for workflow on overburden/bedrock constraint for MVI inversion
Is there any documentation on setting up vector voxel constraints for MVI? The help documentation mentions it, but I'm having little success finding discussions of it. I have a bedrock surface and would like to ensure that the MVI results are confined to the bedrock as can readily be done in susceptibility models. Is this…

Hi, I have some questions about Euler Decon. While we are running Euler method on a gridded data as I understand - from the illustrions ont eh manual and the Theory description- the search window is always moving from right to left and from down to top( west to east and south to north). Here is the question: Would it be…

Can I export only active groups or folders to a new map?
I have a large regional compilation map and would like to save a few specific groups or folders to a new map in order to send to the client. I know that I could do this via duplicate map, but I would need to delete all the other groups and folders and leave only the new work. I can think several of work-arounds, but all…

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…
