To cite specific version numbers of the software, you can use the DOIs provided by Zenodo. Additionally, we ask that when citing the MNE-Python package, you cite the canonical journal article reference [1]:
@article{GramfortEtAl2013a,
title = {{{MEG}} and {{EEG}} Data Analysis with {{MNE}}-{{Python}}},
author = {Gramfort, Alexandre and Luessi, Martin and Larson, Eric and Engemann, Denis A. and Strohmeier, Daniel and Brodbeck, Christian and Goj, Roman and Jas, Mainak and Brooks, Teon and Parkkonen, Lauri and H{\"a}m{\"a}l{\"a}inen, Matti S.},
year = {2013},
volume = {7},
pages = {1--13},
doi = {10.3389/fnins.2013.00267},
journal = {Frontiers in Neuroscience},
number = {267}
}To cite MNE-C or the inverse imaging implementations provided by the MNE software, please use [2]:
@article{GramfortEtAl2014,
title = {{{MNE}} Software for Processing {{MEG}} and {{EEG}} Data},
author = {Gramfort, Alexandre and Luessi, Martin and Larson, Eric and Engemann, Denis A. and Strohmeier, Daniel and Brodbeck, Christian and Parkkonen, Lauri and H{\"a}m{\"a}l{\"a}inen, Matti S.},
year = {2014},
volume = {86},
pages = {446--460},
doi = {10.1016/j.neuroimage.2013.10.027},
journal = {NeuroImage},
}Depending on your research topic, it may also be appropriate to cite related method papers, some of which are listed in the documentation strings of the relevant functions or methods. All references cited in the MNE-Python codebase and documentation are collected in the General bibliography.
