Load Ecotracer

In the Input form

1. set Initial concentration to something 1
2. set base inflow rate to something 1
3. set direct absorption for something at the bottom of the food chain to some value 1 (I'm a simple person)

Output form

1. Run Ecoism (enjoy the way the form disapears)
2. find your way back to the output form 
3. click on some groups
4. close the output form(it should explode)

When Fishing mortality timeseries (type 4) are loaded it overwrites the fishing mortality that is caused by effort sketched by a user in the effort form. This is working and is consistent with EwE5. However, when F timeseries are loaded and different efforts are sketched in after the load, there can be a slight difference in the Ecosm run results. In this case there should be no difference between runs. Mortality should, and does, come from the timeseries. It appears that fishing mortality is coming from the timeseries, as it should, but the sketched effort is having an effect on some other variable that is affecting the run. Both EwE5 and EwE6 do this, at least they are consistent.

One possible source for this kind of a problem would be detritus from discards, as this is calculated from the sketched effort. However, this is not the case in the model I used because it has no discards....

To recreated this create a timeseries for fishing mortality and load it into a model. Turn on the overlays and run Ecosim. Sketch in some major change in effort and re-run Ecosim you should see slight differences between the runs.

Tracer will throw an unhandled exception from the interface if you run Ecosim then Ecospace with Ecospace having a greater number of timesteps.
