When specifying the “At time step” option, I noticed that the output model was not always referencing appropriate model timestep. Everything worked as expected for “At time step” = 1-6 (Jan-Jun), but no model was genearted when “At time step” = 7, and when “At time step” is 8-12 then it writes an Ecopath model at the model timestep minus 10. See status output below. In that example, the model begins in Jan 2009 and I am trying to write an Ecopath model for each month in 2010. So January 2010 would be time step 13, Feb2010=14, Mar2010=15, and so on. You can see that only 11 models were generated, because the July model “At time step=7” would not write, and after June (here timestep=18) it writes models for 10 timesteps previous. So it appears either the status output is incorrect or the “At time step” selection is not indexing properly. not assessed new normal Ecopath 6: Release 6.6 Ecopath from Ecosim plug-in 6.6 beta major
