[Eeglablist] Import timelocked fieldtrip data for plotting

My issues with field trip to eeglab was how it handled trials.

If there were multiple trials it didn't handle it very well. I think it was because the trials were of differing lengths.

I tried writing my own function but I couldn't work out how to handle artefact corrections made in field trip.

Do you still experience the problem?
If so in what sense did fieldtrip2eeglab.m not work? Did it give an error message?

Dear EEGlab-Users,

I am new here and after looking through tutorials and trying my best I finally try to get help this way:
I have EEG Data (ERP P300 Oddball task), originally recorded with an EGI 256 channel system.
I did all the processing (pre and post) with fieldtrip. I now have timelocked data that I want to plot. Fieldtrip only displays a 2D topoplot but I would like to plot the data as 3D on a head or brain surface.

I tried to import my fieldtrip data via the GUI of eeglab, either as .mat or also as -ascii, but I got always the message "unsopported file format".

I know that there is also the function fieldtrip2eeglab.m, but I did not find a lot of info about this (only other mail requests for help with it). I tried it and it also did not work.

I am rather new to both, fieldtrip and eeglab, so I would really appreciate your help and I am sorry if this is a question that you probably get a lot.

Best,
Barbara
