The UV-Vis spectral analysis software a|e has been updated to version 2.2. This new version includes a number of bug fixes and improved compatibility with newer versions of MATLAB.

The number of developers is now doubled

I am particularly happy to have Daniel Aron Gudnason from Aarhus University, Denmark, as a co-developer on this version. Daniel is a talented PhD fellow in optical spectroscopy who will take part in developing the future versions of a|e. Daniel here tells about a new amendment he made for quickly plotting spectral trends over a range of data sets:

Plot trends in multiple data sets

With this new version of a|e a new module, called the “Extracted Value Plotter”, has been added. The modules grants the user the following functionalities: 

  • The ability to plot data points extracted within the program – e.g. single value wavelength intensities or integrated intensities
  • The ability to plot these extracted values for different sets of spectra as data series in the same graph
  • User defined x-values to plot against (time, etc.)
  • Export of the figure for final editing and to be saved in formats supported for matlab figures 
In future releases the following functionalities will be added to the module
  • A general purpose fit tool to fit the data 
  • A way to manipulate with the extracted data series, i.e. arithmetic manipulation 
  • A more integrated way of exporting figures with extra features such as transparent background 
  • More features to customize the produced graphs 
To activate the new feature, navigate to the menu Tools->Plot trends. Once activated, the values obtained when integrating multiple selected spectra or from extracting wavelength values using 'Tools->Data extraction', can be plotted in the trend window located at 'Tools->Plot trends->Open trend window'.

You can develop new functionalities for a|e

Note that you are free to customize the program yourself. Daniel used source files from the MATLAB version of a|e to get acquainted with the program structure before writing the new module. Drop me an email if you too are interested in sharing your developments with other users.

Have a great day!
