Hi Mona,
<div class=""><br class="">
</div>
<div class="">If you directly use the output of ft_read_data as input into ft_appenddata, it won’t work. The reason is that ft_appenddata expects in the input (data#) matlab structures that are generated by ft_preprocessing. Ft_read_data outputs a numeric data
matrix, which is only part of the ft_preprocessing generated output. Have you something like this yet?:</div>
<div class=""><br class="">
</div>
<div class="">cfg = [];</div>
<div class="">cfg.dataset = ;somefiffile.fif’;</div>
<div class="">data = ft_preprocessing(cfg);</div>
<div class=""><br class="">
</div>
<div class="">Best</div>
