Latest release: 4th May (v13.05)
The EPR toolbox project is a major on-going development of scripts and user interfaces that run within the MATLAB environment allowing the completion and automation of many of the every-day tasks associated with Electron Paramagnetic Resonance (EPR). Simple things like loading a spectrum, apply some calculations and plot the results (in publishable quality).
This toolbox started as an amalgamation of a number of my own scripts into one user friendly interface. As it has long been my belief that you shouldn't need to be a programming expert or have a PhD to be able to present your data in a suitable manner and that's where the EPR toolbox comes in.
Where possible, I've strode to use open-source software such that the toolbox remains free to academic users and to avoid the possible problems of copyright. However, some things (notably PowerSat) require the MATLAB Curve Fitting toolbox, but otherwise where possible closed-source and non-free tools are avoided to ensure the toolbox stays free (as in beer, and as in speech).
The toolbox remains a work in progress and all releases should as such be considered as beta software. Whilst I try to test everything before I make it publicly available occasionally things wont work - particularly there are some differences in MATLAB between Linux (that I code on) and Windows. On these occasions I ask for you to have patience and contact me or add it as an issue to github. As yet, I've never failed to come up with a solution within a day or two, and all solutions are fed back into the toolbox ultimately helping other users.
Each script is extensively commented and has a large script description / help section. With any script you should be able to press F1 for help to see the description. Lload the .m file in a text editor allows you to see the help as well as version history for that file. Finally all scripts come with examples of how it use it here on the website.
Finally, I distribute the EPR toolbox under a Creative Commons share a-like license. So please feel free to chop, change and copy any of the code you like. All I ask is that you give me an acknowledgment and feed back any improvements so that others can also benefit.
So, if you have found the EPR toolbox and it has helped you in some way then please consider dropping me an email (it means a lot to receive them) or if you're feeling generous how about buying me a beer/coffee to say thanks?
PS: MMM 2013 is out now and if you look to the Acknowledgements in the user manual you'll see the work here on PDB files has been fed into MMM.
If you find the EPR toolbox useful, please consider buying me a coffee
