[FieldTrip] Error in NM306mag.lay

[Bianca Trovò]

Dear community,

I discovered an error in the magnetometer layout file for the Elekta
Neuromag system (*/fieldtrip-20180910/template/layout/NM306mag.lay*)
present in several Fieldtrip versions (2017 and 2018 at least). Each sensor
name should be preceded by the character 'MEG' but instead only the numbers
are there. This produces an error in some Fieldtrip functions that try to
use the layout (example* ft_databrowser*).
To correct just paste the characters 'MEG' in front of every sensor number
(or use another layout). Example:

*Before*
1 -0.408393 0.273197 0.064507 0.071200 0111
2 -0.328194 0.305701 0.064507 0.071200 0121
3 -0.377055 0.178745 0.064507 0.071200 0131
4 -0.450000 0.110941 0.064507 0.071200 0141
5 -0.310736 0.168122 0.064507 0.071200 0211
6 -0.241095 0.171484 0.064507 0.071200 0221
7 -0.257448 0.057674 0.064507 0.071200 0231
8 -0.326327 0.041365 0.064507 0.071200 0241

*After*
1 -0.408393 0.273197 0.064507 0.071200 MEG0111
2 -0.328194 0.305701 0.064507 0.071200 MEG0121
