PEST error for parameter estimation

Description

Dear Jasper,

As I would like to use PEST to calibrate my model, I encounter an error everytime I try it:
"can't read "runData(node00000,bestPhi)": no such element in array"

LOG:

can't read "runData(node00000,bestPhi)": no such element in array
can't read "runData(node00000,bestPhi)": no such element in array
    while executing
"set closish $runData($myNode,bestPhi)"
    (procedure "FixPredWindow" line 6)
    invoked from within
"FixPredWindow $useNodes($winId,pfit)"
    (procedure "Optimize" line 244)
    invoked from within

    (procedure "Go" line 27)

    invoked from within

    invoked from within
".mre1.mainpw.mainDisplayPane.notebook.fpage0.panedwindow.pane0.container.notebook.results.lbf.upper.start instate pressed { .mre1.mainpw.mainDisplayPa..."
    (command bound to event)

Below are screenshots of the different PEST settings.
For the model used here, it is very simple:
output=inone*intwo
intwo is set to 4 as a fixed parameter, and inone (another fixed parameter) is the one to find (solution should be 5 as it is calibrated on ouput=20)

Also, I already tried re-installing the program, re-setting the PATH variable etc...

So would you know how I could fix this?

I also contacted people from PEST, as I don't know where the error comes from (Simile or PEST..).

Thanks in advance,

Ben

Hi Benedetto,

You have to run PEST at least once in optimization mode before you can turn on prediction. This is because it needs a set of already calculated parameter estimates before it can generate predictions based on the current estimates.

In the next Simile version I will make sure this requirement is reported properly if someone attempts to run a prediction before doing a parameter estimation run. Thanks for reporting this mistake.

Hi Jasper,

Ideed it works if first running an optimization. The result of this is in fact the node0000 variable PEST could not find I suppose.

Thank you

Benedetto
