Features:
- * Huge speed ups for all of the relaxation dispersion models ranging
from 1.366x to 164.180x times faster. The speed ups for the clustered spin
analysis are far greater than for the single spin analysis.
+ * Huge speed ups for all of the relaxation dispersion models ranging
from 1.452x to 163.004x times faster. The speed ups for the clustered spin
analysis are far greater than for the single spin analysis.
* Implementation of a zooming grid search algorithm for optimisation
in all analyses. This includes the addition of the minimise.grid_zoom user
function to set the zoom level. The grid width will be divided by
2**zoom_level and centred at the current parameter values. If the new grid
is outside of the bounds of the original grid, the entire grid will be
translated so that it lies entirely within the original.
* Increased the amount of user feedback for the minimise.grid_search
user function. Now a comment for each parameter is included in the printed
grid search setup table. This includes if the lower or upper bounds, or
both, have been supplied and if a preset value has been used instead.
- * Improved support for R1rho 2D graph plotting in the
relax_disp.plot_disp_curves user function as the X-axis can now be the nu1
value, the effective field omega_eff, or the rotating frame title angle. And
the plots are interpolation over the spin-lock offset.
+ * Expanded support for R1rho 2D graph plotting in the
relax_disp.plot_disp_curves user function as the X-axis can now be the nu1
value, the effective field omega_eff, or the rotating frame title angle. And
the plots are interpolation over the spin-lock offset.
* Ability to optimise the R1 relaxation rate parameter in the
off-resonance relaxation dispersion models.
* Creation of the relax_disp.r1_fit user function for activating and
deactivating R1 fitting in the dispersion analysis.
* Better tab completion support in the prompt UI for Mac OS X users.
For some Python versions, the Mac supplied libedit library is used rather
than GNU readline. But this library uses a completely different language and
hence tab completion was non-functional on these systems. The library
difference is now detected and the correct language sent into libedit to
activate tab completion.

* The value.copy user function now accepts the force flag to allow
destination values to be overwritten.
* Expanded model nesting capabilities in the relaxation dispersion
auto-analysis to speed up the protocol.
* The spin-lock offset is now included in the spectra list GUI
element for the relaxation dispersion analysis.
- * Creation of the relax_disp.r2eff_estimate user function for the
fast estimation of R2eff/R1rho values and errors when full exponential curves
have been collected. This experiment feature uses linearisation to estimate
the R2eff and I0 parameters and the covariance matrix to estimate parameter
errors.

fast estimation of R2eff/R1rho values and errors when full exponential curves
have been collected. This experimental feature uses linearisation to
estimate the R2eff and I0 parameters and the covariance matrix to estimate
parameter errors.
* Gradients and Hessians are implemented for the exponential
curve-fitting, hence all optimisation algorithms and constraint algorithms
are now available for this analysis type. Using Newton optimisation instead
of Nelder-Mead Simplex can save over an order of magnitude in computation
time. This is also available in the relaxation dispersion analysis.
* The minimisation statistics are now being reset for all analysis
types. The minimise.calculate, minimise.grid_search, and minimise.execute
user functions now all reset the minimisation statistics for either the model
or the Monte Carlo simulations prior to performing any optimisation. This is
required for both parallelised grid searches and repetitive optimisation
schemes to allow the result to overwrite an old result in all situations, as
sometimes the original chi-squared value is lower and the new result hence is
rejected.
* Large expansion of the periodic table information in the relax
library to include all elements, the IUPAC 2011 standard atomic weights for
all elements, mass numbers and atomic masses for all stable isotopes, and
gyromagnetic ratios.
