Implementing STEM-EDS quantification

[Steven Spurgeon]

Hello everyone,

I'm a new user of Hyperspy and I'm very interested in quantifying STEM-EDS maps from our JEOL ARM 200CF. I noticed in some of the earlier posts that there have previously been attempts to implement quantification of STEM-EDS data; has there been any progress in this regard? Is it presently feasible to do this with the Hyperspy program or would I have to code something myself?

Thanks,

Hi Steven,

thanks for your interest in hyperspy. EDS quantification (Cliff-Lorimer) is in a development stage. I implemented it and submitted it (pull request) to the development branch of hyperspy. It needs to be reviewed by another hyperspy developper. EDS quantification is planned to be in the next release of hyperspy which should be in few months.

If you want to follow the advance in the development process: https://github.com/hyperspy/hyperspy/pull/389

If you want to try it before, you need to install the development version of hyperspy: http://hyperspy.org/hyperspy-doc/current/user_guide/install.html#install-using-python-installers. For windows, I suggest to install anaconda first (https://store.continuum.io/cshop/anaconda/). Here is an introduction to github https://github.com/hyperspy/hyperspy-demos/blob/master/Github_tutorial_IMC_2014.pdf.
