Dynamique réactionnelle des enzymes rédox multicentres, cinétique électrochimique
Reaction dynamics of multicenter redox enzymes, electrochemical kineticsChanges in QSoas
What’s new in version 3.0 ?
Version 3.0 brings an “expert” fit mode, with a fit command line that makes it possible to automate fitting or do parameter space exploration, running many fits with random initial starting positions to greatly increase the likelihood of finding the best parameters (along with many other new features for fits).
Another improvement in the fits is a new implicit fit, to fit an implicit equation to data.
This release also brings in a command to permanently record information about a file, such as the conditions in which the experiments were made (the sample used, the temperature, etc…), in a format that QSoas automatically reads when reading the file. This makes it possible to quickly browse through data to find the experiments you need.
Finally, this release brings in a whole new offline documentation system, with and index and search facilities, startup tips, cross-reference examples and the possibility to specify manually all the command arguments and options in a dialog box when running a command from the menus.

What’s new in version 2.2 ?
Version 2.2 brings in a lot of new features and improvements, notably
greatly improved memory use for massive multifits, a fit for linear
(in)activation processes, a new way to transform “numbers” like peak
position or stats into new datasets and SVG output ! It also finally
brings back the peak area output in find-peaks
and related
commands !

What’s new in version 2.1 ?
Version 2.1 brings in a number of new functionalities, such as a command to solve equations, and ways to reparametrize fits, along with numerous improvements of already existing commands.
See the full list of changes below
What’s new in version 2.0 ?
Version 2.0 brings a whole new set of functionalities for fits, namely a fit engine with enormous performance increases in massive multibuffer fits (easy to reach a 1000 times speed increase !), definition of fits with a distribution of parameters, and many new functions.

Changes in version 3.0 (03.12.2020)
Fits
The fit system has been greatly improved, with an /expert=true
mode
featuring:
- a command-line interface with over 50 commands in the fit dialog to run fits non-interactively
- parameter space explorers, which run fits systematically with different starting parameters, to improve the chance of finding the best parameters
- possibility to run scripts, even as a
fit-
command-line option, which means one can now perform fully automatic fits - the display, handling, reuse of all the previous fit attempts in a fit session (“fit trajectories”), including ways to highlight changes
- the possibility to set the fit dialog title bar
- a Particle Swarm Optimizer fit engine
- the GSL implementation of the simplex as fit engine
- a mode in
sim-
that just writes the residuals - a mode in
sim-
to export subfunctions - improvements to the parameters spreadsheet
- a new fit,
implicit
, that fits the results of equations to data, together with adefine-implicit-fit
to create named implicit fits - the
arb
fit now has its correspondingsim-arb
function
New commands
- a
mem
command to query for memory usage and set the size of the cache for loading datasets - a

Other improvements
- new syntax for statistics and meta: one can now use
$stats.y_max
(etc.) in addition to$stats["y_max"]
to refer to they_max
stats (and for all stats and meta too), which means that there is no need anymore for cumbersome double quoting like ineval '$stats["y_max"]'
