Version Published Release Notes
3.6.1

enabled Resize
3.6.0

-fixed some parameter names, added missing names
-parameter boxes now sort parameters with values to the top
-can add new parameters if they are missing
-rescaledata & FitOpt.AutoScale default to 'maxabs', FitOpt.BaseLine to 0
3.5.0

- now compatible with easyspin v6
3.4.10

- works with stable versions of easyspin, no change from 3.3 or 3.3.10
3.4.6.47

- fixed bug in dev3.3.6.47 'get esfit fit1' button
3.3.10

- Repackage of v3.3 in order for downloading the latest version not to give you the special dev v3.3.6.47
3.3.6.47

*THIS VERSION ONLY WORKS WITH easyspin dev version easyspin-6.0.0.dev47
*Please download v3.3 or any subsequent v3.# if you are using the stable versions of easyspin, or for the manual and example data/parameters
3.3

- support for change of 'rescale' to 'rescaledata' in dev versions of easyspin
3.2

- edit boxes are now spinners where appropriate
- RMSD is given in the plot when a simulation is plotted over data

3.1

- Now fully compatible with v6.0.0-dev.26 (still fully compatible with v5)
- All functions are now within the App, no more external functions
- "Export Structs" button for quickly exporting parameters to the workspace
- A few bug fixes
3.0

-Bug fixes and improvements in Integrate functions
-New Quantify tab where the coefficients of a calibration curve can be defined and the double integral can be used to calculate spin concentration
2.8

-fixed bug in saving simulated data
-added 'n' to Sys lists for defining equivalent nuclei
2.7

-added option to use the complex portion of the spectrum, if one exists
2.6

-Added slider in the 'Exp' tab for easy frequency adjustment
-Several bug fixes
2.5

-Bug fixes
-Minor layout changes
2.4

-Added dropdown to call 'rescale' for rescaling simulations to data
-Several behavioral improvements
2.3.1

-minor fix
2.3

-Minor bug fixes
2.2

- Added the option to narrow your fit to a specific range in the spectrum
- Added the option to add noise to a simulation
- Fixed bug where the FitOpt structure was not populated
- Other minor fixes and improvements to plotting behavior
2.1

-Fixed bug with baseline percentage sliders
-Added ability to load data that is not on your matlab path, just make sure all companion files (i.e. .DTA&.DSC, or .par&.spc) are in the same folder
2.0

Converted to an App and changed the name to avoid conflict with the actual esfit GUI. Many improvements and new features, check out the manual. Please report any bugs, suggestions, or feature requests.
1.3.0

-More baseline correction options
-2nd Moment Calculation
-Button to add data to workspace
-Expanded default available parameters in the "Sys" boxes
-Updated manual
-Many bug fixes and some code cleanup
1.2.0

- fixed bug with single component simulation
- improved plotting for multi-component simulations
- fixed "get esfit results" to put the results into the correct SYS when not SYS1 or SYS2
