Hi, everyone, Using Concentric Ring Buffer, I'm calculating statistics of about 35 numeric columns in my BlockGroupData.tab. When I request 'proportion sum' and 'proportion avg' of all 35 columns, I get the error 'Unable to open BlockGroupData.map. Too many files open.' When I only do 'proportion sum', all's well. Probably related is the fact that when I load the concentric ring buffer mbx under Tool Manager, I get the notice 'Unable to read preference file , using internal defaults.' Any insight would be most appreciated. Thanks in advance for your help, Erin Rubio Spatial Insights, Inc.
