What's Changed

Add two kinetic models for binding reactions

This commits adds new kinetic models for two binding mechanisms.

  • '3st_induced_fit' models a binding event followed by a change of
    conformation. The binding event parameters are a dissociation
    constant "KD_AB" and an off-rate "KOFF_AB". The change of
    conformation is modeled using two kinetic rate constants: "KBC" and
    "KCB".
  • '3st_double_binding" models a fork model where a protein can bind
    its partner in two different ways. The parameters of the binding
    event AB (AC) are a dissociation constant "KD_AB" ("KD_AC") and an
    off-rate "KOFF_AB" ("KOFF_AC").

The two models require two parameters, "p_total" and "l_total", to be
specified in the conditions.

What's changed

Add models using temperature coefficients

Chemical shifts are now temperature-dependant. In addition, in
temperature dependant models, such as 2st_eyring, it is now possible
to use temperature coefficient by adding the extension .tc to the
model name, eg 2st_eyring.tc.

When temperature coefficients are used, the following relationship
holds:

DW_AB = DWM_AB * T + DWP_AB

where DWM_AB is the temperature coefficient in ppm/ºC, DWP_AB is the
chemical shift difference between A and B at 0ºC in ppm, and T is the
temperature in Celsius. DWM_AB and DWP_AB are fitted and
temperature-independant.

Correct the simulation module

The simulation module was broken: depending on the values given in the
fake profiles, that are necessary to run the simulation, the
back-calculated R2 values were offset differently. This is now fixed.

The calculated profiles are also available in the Data directory.

Correct incorrect 'kij' calculation

What's Changed

Refactor the code related to the kinetic models
A new plugin architecture has been implemented to facilitate the addition of new kinetic models. The code for calculating some of the
constrained rates and populations have been changed to use some optimization calculation instead of an analytical formula (when possible and when the analytical formula is more complicated to read).

'New' kinetic models have been added:

  • "3st_linear": A <-> B <-> C
  • "3st_fork": C <-> A <-> B
  • "3st_triangle": identical to "3st"
  • "2st_a_a2": 2*A <-> A2
  • "2st_a_a3": 3*A <-> A3
  • "2st_a_a4": 4*A <-> A4
  • "3st_a_a2_a3": 2*A <-> A2, A+A2 <-> A3
  • "3st_a_a2_a4": 2A <-> A2, 2A2 <-> A4
