Hi folks,

  I use spmat  to create spatial weighting matrix, and it works fine since :

. spmat summarize cschdist, links

Summary of spatial-weighting object cschdist
---------------------------------------------
        Matrix |                 Description
---------------+-----------------------------
    Dimensions |                   218 x 218
     Stored as |                   218 x 218
 Links         |
         total |                        2800
           min |                           1
          mean |                    5.405405
           max |                          19
---------------------------------------------


While when I run the following command:
. spmat use cschdist using cschdist.spmat
cannot open cschdist.spmat
r(498);

Could someone help me with that?

Thanks,

Wu
