License Required for gxgrd.Grid.minimum_curvature ?

EdwardBiegert

(1) Is there a license restriction for running gxgrd.Grid.minimum_curvature from stand-alone python script?
(2) If so, where in the documentation can I find license restrictions for various functions?
(3) Or is there another problem?


I am running the OM Viewer and this script (pretty much straight from the documentation) failed:


import numpy as np
import geosoft.gxpy as gxpy
import geosoft.gxpy.grid as gxgrd

# ******************************************************
# Gridding test
gxc = gxpy.gx.GXpy() # create Geosoft context
print(gxc.gid) # Prints Geosoft userID

xyv = [(45., 10., 100), (60., 25., 77.), (50., 8., 80.)] # simple data array
grid = gxgrd.Grid.minimum_curvature(xyv)
print('Properties ', grid.properties())

exit()



This is the python response:

Same question.

My guess is that the answer is 1. This page explains that this error will be thrown in the case of trying to use unlicensed functions (https://geosoftgxdev.atlassian.net/wiki/spaces/GD/pages/14582245/Understanding+License+Controls ) It is difficult to unwrap but the GXAPI CLASS for rangrid GXGRD is listed as being for Extended Licenses only (https://geosoftinc.github.io/gxpy/9.10/python/GXRGRD.html ). The definition of this is a bit vague but it requires at least an Oasis license. It appears to have been the case since v9.3 (according to the documentation).
