[FieldTrip] problem with ft_multiplotER

[Sara Bögels]

Hi Jörn and others,

Some time ago, I posted the question below to the mailinglist. I now 
have had this error many times for both ft_timelockgrandaverage and 
ft_multiplotER. It happens for some datasets but not others and this 
appears quite random to me. The error message is:

"Subscripted assignment dimension mismatch"
Error in ft_timelockgrandaverage (line 182).
avgmat(s,:,:) = varargin{s}.(cfg.parameter{k});


It appears to have something to do with the different time limits of the 
different data I want to average or plot. I use cfg.latency to make sure 
the latency falls within the time limits of all files but this sometimes 
still does not help.

Any ideas?

Thank you,
Sara
