Pheonix Modelling giving all modeled concentrations a -1

Is it possible to have to low of a concentration to perform a model. I have model successfully on a few other projects, but this time I don’t get a curve the concentrations are always -1. I am using Pheonix PK modeling. Anyone have any suggestions?

Hi KB,

I think I’d like to see your model, can you post your project here? Elsewise I can look at it confidentially if you add it you your Support case on the same issue. Case 165774.

I will add it to the support case thanks!

I can not figure out how to find the support case it keeps telling me to contact support so I am adding the model here.

thanks I’ve added it ot the support case and will try to look at it shortly, note it is in version 7 of Phoenix.

Simon, If you have not had time to look at my issue support case 165774 that is fine. However I can not find the case how do I get to it so that I can check the progress as it occurs? Thanks

Sorry I overlooked this one as I was on my old machine when you originally replied and when I wen back to my Phoenix 7 machine something displaced your problem from my mind.

I took a quick look, and I made just two small edits, firstly PML is case sensitive so I requested a Capital C for concentration.

Secondly your values are very small so to make sure all doses were presented to the best use of the axis space I set the Y scale in the Ind Simulation plot to ‘autoscale best’.

Simon.
