[FieldTrip] error in ft_prepare_layout

[Robert Oostenveld]

Dear Marijke

That is indeed a bug due to my fault. Please move the lines

% do the general cleanup and bookkeeping at the end of the function
ft_postamble callinfo

from around line 783 to around line 691, i.e. before the subfunction. I have fixed it in the official code, the next release version will be correct.

Robert

After doing the ICA on some EEG data, I tried to look at the resulting ic_data with ft_databrowser(cfg,ic_data), but then I get the following error:

The only time when ft_preamble is called seems to be at the beginning of ft_prepare_layout, and the output of this is not passed on to the other functions it calls.
