Help with a Spatial Autocorrelation error message?

Discussion created by johnpaulmm on Aug 6, 2013
I wonder if anyone can help me please: I am trying to use the spatial Autocorrelation tool on polyline data but I keep getting an error message saying ' Could not open the specified document' but my document is already open. Does anyone know how to overcome this? or know what is menat by the error? The toll does continue to run but consider this erro message comes up then I presume it isnot running correctly although I have not allow it run to completion.

I should say I am using Arcgis 9.2.

Any help would be  greatly appreciated.
