weights matrix (.gal) failing

Hi all,

I generated a spatial weights matrix using Pysal, and am now trying to compute local moran's I statistics in ArcGIS (v.10).  The extension for the spatial weights matrix is .gal.  I went through the weights matrix and tried to make sure that the format was compatible with ArcGIS (i.e. changed the header to the id variable name, got rid of all "islands").  However, when I try to execute "Cluster and Outlier Analysis", I get the error message "Invalid text weights format."  It's working fine in Geoda, but I prefer to use ArcGIS:)

Does anyone have any ideas what might be causing this?

Thanks!

Saul
