[FieldTrip] problems with topographic plotting

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

Hi Ivo,

You report an error in ft_getopt.m, line 41.

My version of the code (in fieldtrip/utilities for example) lands somewhere in the function’s doc-string. In other words, in your case Matlab sidetracked into an (old / strange / un-updated ) version of the code.
Perhaps things will be solved if you define a clean path.

Best wishes,
Jan-Mathijs

Dear community,

I would like to plot pre-calculated averages/electrode onto a head-model (easycapM1)
These are averages (across subjects) of ITC values (inter-trial coherence) and
for reasons I can elaborate on request it was the easiest to store these values
in a separate column vector than to let topoplotER work on top of the ft_freqanalysis. Something seems lost in translation. Even when I create a structure around the vector (making sure it's fields),
topoplot_ER does not want to work with it. Specifically the error messages I get are:

Error using fieldnames Invalid input argument of type 'cell'. Input must be a structure or a Java or COM object. Error in ft_getopt (line 41) prop_names = fieldnames(opt); Error in removefields (line 36) recursive = ft_getopt(varargin, 'recursive', false); Error in ft_preamble_provenance (line 51) cfg.callinfo.usercfg = removefields(cfg, ignorefields('provenance')); Error in ft_preamble (line 83) evalin('caller', full_cmd); Error in ft_topoplotER (line 177) ft_preamble provenance varargin Error in human_consfigure (line 7) ft_topoplotER(cfg,Structia.freq)

Thank you dearly in advance, bests,
