Issues with restarting

[ArMOdr]

Hi
I am trying to re-start my PEST run. I have these lines to my pst file.

++ ies_restart_observation_ensemble(03.0.obs.csv)
++ ies_restart_parameter_ensemble(03.0.par.csv)

Both 03.0.obs.csv and 03.0.par.csv look fine.

When I try to restart, I get the below error. Any idea what the issue could be?

Cheers

The restart for ies is confusing and a lot of it has to do with allowing par and obs (and noise) realizations that have different names. The short answer is you need to pass ies_parameter_ensemble(03.0.par.csv), ies_observation_ensemble(03.obs+noise.csv) and ies_restart_observation_ensemble(03.0.obs.csv). You dont need to pass ies_restart_parameter_ensemble in most cases (its only needed if you want to track parameter changes from the initial/prior ensemble, but you are restarting with the prior ensemble, so its irrelevant).

Also, just a heads up: if your control file is named "03.pst", then when you restart, ies will stomp on "03.0.obs.csv", "03.obs+noise.csv" and "03.0.par.csv"
