[FieldTrip] Problem with Multiplot_TFR

[Schoffelen, J.M. (Jan Mathijs)]

Hi Elene,

This is not possible from the label field alone. If anything, you also need a specification of corresponding positions (either in 3D space, or as a 2D projection).
Please refer to http://www.fieldtriptoolbox.org/tutorial/layout/ for more information. If there is, as I suspect in your case, a mismatch between the exact label names, and the names of the labels in one of the existing layout files (e.g. biosemi128.lay), you can consider making your local copy of that file, and adjust the names of the labels according to your needs (e.g. change ‘Fp1' into 'Fp 1’ or so).

Good luck,

Jan-Mathijs

Hi,

And is there some way of creating a layout from the *.label field?

Thank you in advance

Elene.

Hi Elene,

Please check the names of the electrode labels in the layout file, and compare them with the ones in your *.label field.
Only the exactly matching tokens will be shown in the figure.
