Objectives
|
- Test the protein display model and find to what kind of values it's sensitive to.
|
- Define the control volume around the bacterial cell.
- Start on testing the model.
|
- We realised that it would be worth adding the last step (colour production by dioxygenase) into our amplfication models.
|
- We need to finalise testing and formulation of certain assumptions regarding the amplfication (cell death in particular).
- Consider helping RMIT- Australia in modelling.
|
- Keep exploring the prospective solutions to our system going unstable.
- Try to implement the last bit of amplification in TinkerCell. Maybe it will deal with it well.
|
Completion
|
- We couldn't reach the testing as the first model "Display 1" was simulating reactions as if the were taking place inside the bacterial cell while in reality the take place outside. Then we hit an issue of defining the size of volume around the cell. We didn't manage to resolve that problem today.
|
- Control volume defined.
- Testing of model done.
- Protein model pretty much finalised.
|
- The colour production almost complete, however complications were encountered regarding the cell death (colour compound slowly kills cells).
|
- Basically we're stuck: scaling didn't help neither did trying idfferent solvers.
- Meeting with Matthieu gave us some prospective solutions that we can explore.
- Alternatively we can have a look at SimBiology or MatCont.
- Helping RMIT: their request is for protein engineering simulation - we cannot do that
|
- We know how to use the ''splinetool'' in Matlab.
- Specifying the time span helps to reduce the simulation time.
- Model was implemented in TinkerCell.
- Increasing relative or absolute tolerance in Matlab prevents some solutions from going negative. The key point is that we are only interested in the first few minutes of the experiment as the reaction to catechol is really quick.
