Re: [UrbanSim-Users] Converting Data from Version 4.0 to 4.1.2

Zak,
Your land_price_model_specification contains a variable in old expression
style:

opus_core.func.ln(urbansim.gridcell.total_improvement_value)

which has been converted to ln(.). You can find more about expression
from here http://www.urbansim.org/opus/releases/opus-4-1-0/docs/opus-userguide/node79.html

Liming.
