[Eeglablist] fieldtrip to eeglab

Hi Federica,
The filedtrip2eeglab program only works when your data is in a certain
format in which the trial field in your data should be 1 x N cells. N
stands for the num of trials. In addition, the time information should also
be saved in one or certain number of cells.   When your data format does
not match with this the program will not work.
Also, the original field2eeglab program needs a string input for the file

So, you either need to adjust your data structure or modify the
fieldtrip2eeglab program to fit your data.

Good luck.
