EEG and MEG
Sylvain Baillet wrote a recent review manuscript on Magnetoencephalography for brain electrophysiology and imaging in Nature Neuroscience (2017).
A comprehensive introduction in the neurophysiology and biophysics of EEG (also relevant for MEG) is given in Electric Fields of the Brain: The Neurophysics of EEG, 2nd Edition by Paul L. Nunez and Ramesh Srinivasan.
Steven J Luck, An Introduction to the Event-Related Potential Technique, MIT Press: 2005, ISBN 0262621967. This book is reviewed here: Peter Hagoort (2006) Event-related potentials from the user’s perspective; Nature Neuroscience 9, 463.
The brain in time: insights from neuromagnetic recordings by Riitta Hari, Lauri Parkkonen and Cathy Nangini gives a comprehensive introduction to MEG.
Guidelines for acquisition, analysis and publication
Specifically for MEG we recommend the Good practice for conducting and reporting MEG research paper by Joachim Gross et al. that was published in 2012 in NeuroImage.
When doing clinical MEG, please check IFCN-endorsed practical guidelines for clinical magnetoencephalography (MEG) in Clinical Neurophysiology, 2018.
Terry Picton et al. published the Guidelines for using human event-related potentials to study cognition: recording standards and publication criteria in 2000.
The Society for Psychophysiological Research published this Committee report: publication guidelines and recommendations for studies using electroencephalography and magnetoencephalography in 2013.
The OHBM Committee on Best Practice in Data Analysis and Sharing (COBIDAS) wrote a report on Best Practices in Data Analysis and Sharing in Neuroimaging using MRI. Although this is on (f)MRI, the parts on subjects, tasks and data analysis are also relevant for EEG and MEG. The report was published in Nature neuroscience in 2017.
The International Pharmaco-EEG Society (IPEG) published their Guidelines for the Recording and Evaluation of Pharmaco-EEG Data in Man in 2012.
If you are doing clinical EEG or MEG, you should check out the Guidelines and Consensus Statements of the American Clinical Neurophysiology Society (ACNS) and the guidelines of the International Federation of Clinical Neurophysiology (IFCN). The IFCN also refers to the published Recommendations for the Practice of Clinical Neurophysiology.
Nature has a Reporting Checklist For Life Sciences Articles that is helpful to consider when you write your manuscript, also when you don’t plan to submit it to Nature.
MathWorks provides online tutorials to help you get started with the desktop and programming environment.
For an introduction to MATLAB have a look at the excellent tutorial and exercises in MATLAB for Psychologists.

In MATLAB you have the command window, on Linux, macOS and Windows you have the terminal and the Bash command line. With Discovering the terminal you can get a 30-minute introduction in how to use the Bash command line.
Richard Johnson has written a MATLAB style guide that explains how to write code that is more likely to be correct, understandable, sharable and maintainable.
For data sharing we recommend that you consider organizing your data along the lines of the BIDS standard. See The brain imaging data structure, a format for organizing and describing outputs of neuroimaging experiments for an introduction and MEG-BIDS, the brain imaging data structure extended to magnetoencephalography. The ** data2bids** function helps to organize your data in the BIDS structure.
A good example for a data publication is given in A multi-subject, multi-modal human neuroimaging dataset, which includes MEG, EEG and fMRI. The dataset itself is available from OpenfMRI.
The Human Connectome Project (HCP) also provides good examples for data sharing and documentation. In Adding dynamics to the Human Connectome Project with MEG the MEG component of the HCP is described, which is available for download from the HCP website.
