Working with MATLAB Day1
Researched Sensitivity Analysis:
Intro into sensitivity Analysis , by Lucia Breierova and Mark Choudhari... Content: Examples / Tutorial on how to do sensitivity analysis on data ( No examples related to our work) Learned: Sensitivity investigates the robustness of a study when the study includes some form of math modelling. Sensitivity allows the modeller to determine what level of accuracy is needed for a parameter to make the model sufficiently useful and valid. When the parameter is insensitive in the model , making an estimation is a good idea. With Systems Dynamic models the k parameter doesn't affect the behaviour of the graph . The shape of the graph stays the same . Matlab Programing: Looked into the effect of changing the kinetic constants on the graph. This resulted in no change in the behavior of the graph as predicted by the paper. The max/min/ steepness of the graphs changed as a result of changing k values. The change of some k values effected the steepness of the lines very much while changing the value of other k values didn't change the steepeness all that much. Also looked into the effect of changing the initial concentration of the species . This completely changed the behavior of the graphs. Looked into sensitivity analysis with simbiology interface . Still trying to work out some kinks.

Ethics and Marketing for August 17th 2009
Today, I concentrated my energies on working on the ethical aspect of our project and did some marketing for our project. I started my day by working on the ethics essay that we will be writing for our project. I edited the essay and added some more information to elaborate on some topics. It is still not complete but I will be working on it for the whole week.
For marketing, I contacted my team-mates who are working on 2009 iGEM Calgary Shirts and asked them if they needed any help. I will be contacting the contact for the shirts company and ask them for a better deal on the shirts or a possible partnership. I also worked on the August Newsletter; I started to write a couple of write-ups for some sections that we will be adding to the newsletter.

Working on Paper
I am gathering information needed to write down the paper we have been asked to write. I have written some sections so far.

Completion of DNA Replication and More Writing
I was able to complete a blog update that will be posted sometime on Tuesday and DNA replication was completed except for the user prompts that will be included with the notecard. I had to make single stranded binding proteins that attach close to where the helicase is and the primase will only rez one set of primers, which is the same for DNA polymerase until it has been reset. Other things that I made today were:
I also posted wiki updates for the majority of May and also made a couple for July. I have now begun on my wiki notebook for June, which I would like to complete by Wednesday at the latest.

Construction of Pqrr4+B0034+K082003
Once again, the Pqrr4+B0034+K082003 circuit was constructed. This time, the vector was Pqrr4+B0034 Colony 1. The vector was cut with SpeI and PstI, and the insert, K082003, was cut with XbaI and PstI. The vector was phosphotase treated, and then they were ligated together. Next, this constructed circuit was transformed into TOP10 cells and are now growing on Kanamycin + Chloramphenicol plates.
Modelling Blog
Another Modelling blog was written today. Most of the modelling work last week was done by Vicki and Chinee, working hard to track down those sensitive parameters. Here's the link to the blog:
Sensitivity analysis: Models... have feelings too!

PRIMA
Colony PCR and Marketing
It turns out that I had used the Low-melt agarose on Friday to make my 1% gel. Unfortunately, the gel didn't turn out well and I had to postpone my work to Monday. Today, I made a 1% gel with the normal agarose powder and remade my stock (3 microL PCR product, 2 microL dye & 15 microL ddH2O) and ran my gel at 100V.
The results showed exactly what I was expecting. Since I had used regular BBK CP primers and length of my construct was 885bp, the total length of the bands should've been 1135bp. My bands were just above the 1kb ladder band! I let the students visiting our lab make my overnight cultures. Tomorrow, I'll do a mini-prep and a restriction digest to verify the size of my construct. If all else is good, I'll send it to sequencing.
I followed up with the T-shirt company but unfortunately I couldn't get a hold of her. I'll follow up tomorrow. I also called numerous new companies and sent our sponsorship package to one of them. I left a voice mail for the rest of the companies. I'll follow up with them tomorrow. I also began write-ups for the August newsletter.

Sensitivity analysis and parameter optimisation
My primary goals for today were:
SENSITIVITY ANALYSIS I followed the SimBiology example and applied that to the WithoutAI-2 system. While Chinee collected information on what affects the sensitivity of the outputs with respect to different parameters, I worked out how to automate that at the command line level. I explored GFP output specifically, with respect to 5 different parameters. Of those, my results showed GFP displays high sensitivity to parameters 1, 3 and 4; and very low sensitivity to parameters 2 and 5. PARAMETER ESTIMATION To support the sensitivity analysis, I performed the parameter optimisation on each of the 5 different parameters to try to fit the curve to output data that I made up. The idea is that if you can optimise just one of the parameters and fit the curve to the data, it means that the system is highly responsive to tweaking of that one parameter. The results of this were encouraging: by modifying either parameters 1, 3 or 4, I was able to achieve a 92% fit. However, even when I optimised parameters 2 or 5 as much as I possibly could, I could only achieve a 40% correlation. This supports the results of the sensitivity analysis, by showing that the system is most responsive to parameters 1, 3 and 4. I then conducted the optimisation on parameters 1, 3 and 4 all at once. The results were surprising: the R-squared fit was .92 - slightly higher than by just tweaking parameters 3 or 4, but slightly lower than when I only tweaked parameter 1. I will explore this further to see what is going on. If anyone would like a demonstration, these results can be seen by using the command "do_work" on my computer.
