To make the correction:1) Navigate to the Scripts folder and locate the <a href="http://KFunction.py" target="_blank">KFunction.py</a> script: <ArcGIS>\Desktop10.0\ArcToolbox\Scripts2) Create a backup copy of this script file (name the copy something like <a href="http://KFunctionSave.py" target="_blank">KFunctionSave.py</a>)... this is just in case something goes wrong.3) Open <a href="http://KFunction.py" target="_blank">KFunction.py</a> with any text editor (like Notepad, for example). Alternatively, from within ArcMap right-click the K Function tool (via the Catalog or the ArcToolbox pane) and select Edit to access the source code.4) Locate the following section of code (at about line 517) and under the line "if not inside:" change the variable "newTable" to "simTable"#### Resolve Simulate Points ####if self.simulate: simTable = GAPY.ga_table() tempN = len(newTable) simID = self.maxID + 1 for i in xrange(tempN): row = newTable[i] id = row[0] x,y = row[1] simTable.insert(id, (x,y), 1.0) if near[id] <= self.stepMax: nearX, nearY = nearXY[id] dX = nearX + (nearX - x) dY = nearY + (nearY - y) point = (dX, dY) inside = UTILS.pointInPoly(point, self.studyAreaPoly, tolerance = self.tolerance) if not inside: newTable.insert(simID, point, 1.0) ## change "newTable" to "simTable" on this line: simTable.insert(simID, point, 1.0) newSimDict[simID] = id simID += 1
