- | == Workflow ==
| |
- |
| |
- | * Study [[Team:BCCS-Bristol/Modeling/Ideas]] to understand high level development goals (you can add stuff to that page!)
| |
- | * Decide the specifics of what needs to be done and add items to your to-do list. Ideally the items added should read like commit messages
| |
- | * Commit to the [http://code.google.com/p/bsim-bccs/ subversion repository] and <s>strike out</s> the item on your to-do list, adding a reference to the commit number if possible e.g:
| |
- | ** <s>Rename BSimObject to BSimParticle</s> r19

- | * Meet Sean Davies re: beads - try to bring some polystyrene beads
| |
- | * Learn something more about bioscaffolds
| |
- | * Contact Paris team re:video
| |
- | * Decide whether we are talking at the synbio conference, if so, who is talking
| |
- | * Identify what batch simulations we wish to carry out asap. See [https://2008.igem.org/Team:BCCS-Bristol/Modeling-Batch_Simulations].

- | * Study whether 3D implementation of newPosition in BSimBacteriaCreate is reasonable r28
| |
- | * 3D tumbling in BSimBacteria r30
| |
- | * 3D diffusion for BSimChemicalField r29
| |
- | * 3D boundaries r34
| |
- | * If our paradigm is particle dynamics, interactions with solid boundaries (that have a shape) are making things more complicated than neccesary.. traer physics is proving a big inspiration, it's beautifully simple - following its lead I believe we could dramatically decrease the complexity of the bsim physics engine
| |
- | * We are going to have to implement collision detection for vesicles - once it's in, perhaps we should use it for bact-bact and bact-bound too.. we probably only need _real_ physics for bact-bead?
| |
- | * Remove author, date from headers?
| |
- | * Further refactoring to achieve clear and consistent class-package naming: make toolbar a nested class of app?
| |
- | * Are PART_PART, PART_BACT, PART_BEAD really neccesary?
| |
- | * Add paper references to parameter values in the code using [https://2008.igem.org/Team:BCCS-Bristol/Modeling-Parameters|a page from last year]
| |
- | * <s>Improve knowledge of rigid body collisions</s> [http://chrishecker.com/images/e/e7/Gdmphys3.pdf] [http://www.cs.lth.se/EDA046/lectures/L3.pdf]

| |
- | * Fix BSim bug
| |
- | ** When the bacteria have a large enough force and the time step is not small enough the bacteris are able to 'escape' the boundary.
| |
- | ** Fix this by checking the distance and direction of all the bacteria close to the boundary. This will catch those that have moved outside the boundary in one time step.
| |
- |
| |
- | * Understand how bacteria "tumble" under magnetic force
| |
- | ** It is believed that the magnetic force causes the bacteria to orientate in line with the field and so the tumble phase will not occur.
| |
- |
| |
- | * Finish coding the magnetic force for variable magnetic force
| |
- | ** Code the magnetic force as an additional force on the bacteria along with the internal and external forces.
| |
- | ** Find realistic values for the magnetic force acting on the bacteria.
| |
- |
| |
- | * Code half-coated bead
| |
- | ** Apply two different potentials to each half of the bead - one side has a potential well (the bacteria attach here) and the other side has no well (the bacteria will interact normally here).
| |
- |
| |
- | * Control which objects are affected by the magnetic force
| |
- | ** Magnetotactic bacteria in a constant magnetic field
| |
- | ** Magnetotactic bacteria in a variable magnetic field
| |
- | ** E. coli attaching to a magnetic bead under a variable magnetic field

| |
- | *GRNs and vesicles
| |
- | ** Read more about the mechanics of different GRNs (specifically switches).
| |
- | ** Find out how they interact with the external environment.
| |
- | ** Investigate the possiblity of using a different time-step to the fixed one in BSim.
| |
- | ** Investigate the effect of different time steps (GRNs operate on a time scale relatively long compared to that of BSim).
| |
- | ** Investigate the mechanics of our GRNs with respect to vesicle budding and communication.
| |
- | ** Investigate methods for numerically solving stochastic ODEs.
| |
- |
| |
- | *BSim GRNs
| |
- | ** <s>Java implementation of Runge-Kutta 4th order solver.</s>
| |
- | *** Refactor ODEs from an interface to an abstract class if necessary.
| |
- | ** Investigate other options in terms of external libraries (eg odeToJava - good but seems overcomplicated for current purposes; hundreds of lines of code for one solver routine)
| |
- | ** Implement the solver into BSim.
| |
- | ** Implement other solvers (more efficient) and the ability to choose between them.
| |
- | ** Extend to Stochastic ODEs.
| |
- | ** Interface BSim with external parameters (maybe similar to current parameter files) used to define an ODE system.
| |
- | *** Investigate the feasibility of SBML parameters or a similar XML based format.
| |
- | *** Similarly investigate the format used by XPP (may be more succinct, also is specifically for ODEs).
| |
- | ** Investigate and implement GRN (ODE) and chemical field interaction.
| |
- | *** Study implementation of 3D diffusion in BSim.
| |
- | *** Implement diffusion in/out terms for membrane diffusion.
| |
- | ** GRN interaction with vesicle budding and chemical transport (on the surface of the vesicle and inside it).
| |
- | ** Incorporate a method for seeing the effects of GRN activity (eg colour changes, pop-out time series).
