Export from MoBi into population simulation with dimensionless parameter state variable

[RKasp]

Hello all,

Please ignore my posting in the Forum, I think this is the wrong location.

I am having an issue when exporting a MoBi file into the population simulator.

I needed to introduce a dimensionless parameter state variable (fraction) but the export to the population simulator seem not to allow such step. Is there a solution to this problem or can I work around it?

The message: Could not load simulation from ...
Dimension dimensionless per time not available in DimensionFactory.

Thank you.

Best regards,

Rudiger

@RKasp This seems to be a bug in MoBi. It is creating a dimension Dimensionless per time instead of using the one already available Inversed time

I needed to introduce a dimensionless parameter state variable (fraction)

Can you set the dimension to fraction instead and see if this work?

I just tried, same error message...
Now it says:
'Dimension fraction per time not available in DimensionFactory.'

hum ok.
WE are going to give it a look

In the meantime, here is a workaround

• goback to your dimensionless parameter
• Then SAVE the simulation as pkml file (instead of exporting it direclty) for population
• Open the pkml file with a text editor (notepad ++ for example)
• Search for Dimensionless per time
• Replace with Inversed time
• Go to pksim and select
  

This should be equivalent

Can you add your workaround here? Hopefully it's easier than mine :)

thank you! Your approach works.

My workaround (if still needed):

1. Open the file "C:\ProgramData\Open Systems Pharmacology\PK-Sim\7.4\OSPSuite.Dimensions.xml" with a text editor
2. Add the block

  	<Dimension name="Dimensionless per time" baseUnit="/min">
      <BaseRepresentation lengthExponent="0" massExponent="0" timeExponent="-1" electricCurrentExponent="0" temperatureExponent="0" amountExponent="0" luminousIntensityExponent="0" />
      <Units>
        <Unit name="/min" factor="1" />
      </Units>
    </Dimension>
