[FieldTrip] define trials from multiple datasets

[Max Cantor]

Hi fieldtrip community,

I'm trying to use ft_definetrial to create a trial definition from 8
datasets, recorded back-to-back from a subject, and then use
ft_redefinetrial with that trial definition and raw data that was
concatenated in eeglab and converted to a fieldtrip structure using
eeglab2fieldtrip. Is this feasible in a relatively straightforward way, or
would I be better off doing the epoching in eeglab as well before
converting back to fieldtrip?

On a side note, I chose to concatenate the data in eeglab because I could
not figure out a convenient way to do so in fieldtrip. I know there is
ft_appenddata, but as best as I can tell this is meant to be used after
epoching, and the sample information was not being concatenated (or at
least not properly), which was creating problems down the line with
artifact rejection in my pipeline. Maybe there was some other way to do
this properly in fieldtrip that I had not considered in the first place.

Best,

Max
