Julia.

Using the new version, when I try to build the W matrix, the program answer me that my data has 'Null geometry was detected in dataset. Geoda can't create weights with NULL geometry', I have checked the data and it is correct. If I move to the previous Geoda version, I can build the matrix.

Could you help me?

Thanks, Paloma

Hi Paloma,

If you can send me the data offline, we'll take a look.

Best, Julia
