Week 1
02/07
After a brief re-introduction to the Laboratory and our project proposal, we outlined a 6-PHASE approach to guide our practice over the summer.
From here the Modellers began working on basic Matlab modelling tutorials, designed by Xu Gu, to allow all modellers to reach a satisfactory ability. By the end of the day we had completed a number of Mass-action programs using the ode45 funtion and grasped the translation from basic notaion into Substrate, Enzyme and S/E-complex notation.
03/07
We developed our modelling techniques by programming responses to basic metabolic and signalling pathways. We then learnt more precise techniques of modelling, e.g. accuracy and tolerace variance and noting parameters. We then covered Loop and Switch functions.
04/07
We were introduced to the 'Nested Functions' to allow for simpler programming, and the basic ideas behind Sensitivity of output due to a range of possible values of varying constants.
In the afternoon, all modellers were shown some Wetlab techniques for the sake of a more thorough understanding of the processes involved.
Our experiment was to extract plasmids from a number of different bacterial cultures.

06/07
Raya Khanin introduced us to the Michaelis-Menten equation and its use in biochemical process modelling. We then discussed the methods of modelling different promoters's 'Acceptablility', i.e. 'And', 'Or' and 'Sum'.
Week 2
09/07
Our first step towards modelling a possible method for PHASE 1.
10/07
We planned and gave a lecture to those in Wetlab, explaining the methods we employ, as modellers, to represent various biochemical reactions. We also received a complementary lecture from those in Wetlab explaining the processes they employ to carry out and observe experimentation.
11/07
We have finally agreed on model we are going to simulate, but wet lab updated us, that first experiment went wrong and we have to remodel. First few minutes after such news were shocking. It took us an hour to finalize all the details. And now we have to go again.
Lucky for us, modelers, computers dot care much about bacteria used in the experiment so as long as we follow the same pathway, we only need to rename variables. Bless!
12/07
A day dedicated to manual math's, as Rachel and Kristin does some analytical derivations for our model's optimization. To be honest, we were very optimistic about the outcome, and though, the formula derived were fine, and simulations went on as smoothly as ever, the optimization part shoved that 9 dimensional space is though nut to crack, even for MatLAB.
13/07
Some introduction to Stochastic Modelling intrinsicaly contained in gene transcription. We took some decisions about the design of the wiki. More optimization done by Maciej.
Week 3
16/07
Glasgow Bank Holiday.
17/07
We were given a brief introduction to Bionessie and SBML. Also we be begun to get to grips with Global Sensitivity analysis.
18/07
A brief overview of SimBiology was given to the drylab by Gary. Martina and Rachel continued learning about Stochastic modelling, while the rest of the team were working on Sensitivity Analysis.
19/07
A presentation was given to both, the wetlab and the drylab, about the Full Text Fetcher programme which, will help to search and retrive research articles.
20/07
Today we realized that, we missed few important details in our model 1. All morning was like one big mess. Everybody gave their ideas how things should be sorted. Eventually, we settled our brainstormed ideas on board and decided to leave simulations for Monday because new parameter hunt for model 1.2 was about to begin…
Week 4
23/07
Day spent on long discussions with Raya about the accuracy of our model 1.2 . We finally simulated it and… Results were a bit, shall I say, unpleasant. Because of signal degradation, we will not reach a stable state as we anticipated before. That is going to mess up our optimization algorithms, for sure.
24/07
Kristin was asked by Xu to introduce Petri Net([http://www-dssz.informatik.tu-cottbus.de/index.html?/~wwwdssz/software/snoopy.html Snoopy]) method to qualitatively analyse the dynamics of the system. And Karolis, introduced a dynamical approach in modeling of the system using Simulink. Both methods rely not only on blunt programming, but introduce GUI (Graphical User Interface) logics.
25/07
Maciek started a thorough research of registry files, because we were told by dry lab, that they are about to deposit their first brick and, it is not very intuitive (a good point for registry’s future development). He promised to study it and give us all tutorial about his findings.
26/07
Bricks. Brick Bricks. What is this brick? What is the aim of having bricks? All these questions were brought forward and we all agreed to do a thorough individual research and combine them in joint brainstorm, because as our grandfathers used to say: ‘There are as many opinions, as there are heads’.
27/07
First bricks from Glasgow team reached a sandpit. No no. Do not rush to copy them. That’s just a ‘getting used to the system’. We are about to deposit real one, so we want everything to go as smooth as possible.
Week 5
30/07
Maciek’s tutorial enlightened wet and dry labs about all the registry’s pluses and minuses. We now know how to deposit a brick, edit it and etc. During this tutorial we compiled a list of ides and suggestions how to update the concept of brick itself, and some suggestions for registry’s future.
31/07
To pursue the further ideas about Brick-Based system modeling Karolis introduced some CAD ideas for possible GUI algorithm and code development.
01/08
When the day was about to be over, we received long awaited news… First experimental data have finally reached us. We will be able to do some curve fitting, parameter estimation and other cool stuff.
02/08
Today we brainstormed the data we have. Everybody added their bit to ideas pot, however, since the data wasn’t that plentiful as we expected, we queried wet-lab for some more input. They promised that more data is on the way.
03/08
Friday. The end of week 5. Our project just passed major milestone. No, not in development, but in time left available for us to complete it. We are officially halfway to successes now?
Week 6
06/08
Today we received extra data to support our estimations. General modelers meting raised issues like the further development of the model, feedback loops, or our possible influence for wet lab. Now that we have some data (input) we should produce some output for near future projects.
