mixed formatting and doc improvements

[sappelhoff]

minor changes while I was going through the codebase.

Points I noticed:

• It is unclear how to get the MRI data for the "example" described in the README
• The "example" data on OSF contains an empty system calibration files directory in LocalizerDATA ... is this an error?

[jasmainak]

MRI documentation is kind of sparse in MNE as well :-)

maybe you can adapt this somehow:

https://github.com/mne-tools/mne-biomag-group-demo/blob/master/scripts/processing/01-anatomy.py ?

no objection to merge but FYI the readme file is not really up to date as we use here sample. The readme comes from this fork. https://github.com/brainthemind/CogBrainDyn_MEG_Pipeline

[sappelhoff]

Okay, but is this master? Or has that fork now become master?

Where should I primarily work so that I don't cause conflicts?

Feel free to merge

[agramfort]

don't worry. Nothing is released yet. We can do things manually later. Make it work. We'll make it nice later

this one can be merged I believe

[jasmainak]

Merged, moving on to more serious contributions ;)

[sappelhoff]

yes! perhaps you could review https://github.com/bids-standard/bids-validator/pull/789? it's blocking mne-tools/mne-bids#209
