A collection of scripts and functions for the analysis of atom probe tomography data. Currently, this includes: standard file operations, plotting mass spectra, mass spectra analysis and mass peak overlap solving.
For more information see the Wiki: https://sourceforge.net/p/atomprobelab/wiki/Home/

For details of the maximum likelihood method used to solve peak overlaps see the following papers: https://doi.org/10.1017/S1431927616012782 and https://doi.org/10.1017/S1431927618016276 for the quantification of the uncertainty.

Project Samples

Single-ion peak deconvolution using AtomProbeLab Overlap graph created using AtomProbeLab. Nodes are ions, links show which ions have peak overlaps. The number on each line shows which positions are overlapped and the line thickness shows how difficult the problem is to solve (thicker = higher uncertainty) Mass peak plotting
