<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>We realised that it would be worth adding the last step (colour production by dioxygenase) into our amplfication models.</li> </ul>

   </td>

   </td>

<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>Keep exploring the prospective solutions to our system going unstable.</li> <li>Try to implement the last bit of amplification in TinkerCell. Maybe it will deal with it well.</li> </ul>

<ul> <li>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.</li> </ul>

   </td>

<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>The colour production almost complete, however complications were encountered regarding the cell death (colour compound slowly kills cells).</li> </ul>

   </td>

<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>Basically we're stuck: scaling didn't help neither did trying idfferent solvers.</li> <li>Meeting with Matthieu gave us some prospective solutions that we can explore.</li> <li>Alternatively we can have a look at SimBiology or MatCont.</li> <li>Helping RMIT: their request is for protein engineering simulation - we cannot do that</li> </ul>

   </td>

<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>We know how to use the ''splinetool'' in Matlab.</li> <li>Specifying the time span helps to reduce the simulation time.</li> <li>Model was implemented in TinkerCell.</li> <li>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.</li> </ul>

   </td>

<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>Update Modelling section of the Wiki.</li> <li>Update list of experiments (especially for Protein Display Model) and discuss with Chris and Wolf.</li> </ul>

<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>Tinkercell is not very good at dealing with very high or low values.</li> <li>SimBiology package generates same graphs as our manual simulations. The interface is quite easy to use.</li> <li>Decreasing absolute and relative tolerances is becoming accpeted as a solution to a negative concentrration problem.</li> </ul>

   </td>

<td style="background-color:#eeeeee;height:200px;width:200px;text-align:top;"> <ul> <li>Modelling of false positive in display protein is postponed as more research need to be done on the affinities etc.</li> <li>Presentation was given - feedback is to be implemented.</li> <li>It was deduced that we should model the cells as alife, because of the slow cell death induced by addition of catechol.</li> <li>Matthieu was consulted and the feedback is posted here.</li> </ul>
