<p class="MsoNormal">Hi Moumita,</p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Maybe try to add the path before, adding a line like :</p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">addpath(‘F:\data_fldtrp’)</p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Then you should be able to call your dataset with the first set of commands your wrote.</p>
<p class="MsoNormal">I hope this helps.</p>
<p class="MsoNormal">Alternatively, the second option you mentionned should also work, but the file you are calling is not the same in the two examples.</p>

<p class="MsoNormal">Hello,<u></u><u></u></p>
<div>
<p class="MsoNormal">I am a novice in fieldtrip. Trying to learn it for my EEG analysis, on my own. I don't have any local group with whom I can discuss the problems I am facing here. I am trying to import continuous data into the fieldtrip for ft_preprocessing.
Since I need to do ft_definetrial first for which I need to know the eventtype and eventvalues first, I tried calling ft_definetrial with cfg.dataset. <u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">I gave the following command:<u></u><u></u></p>

cfg.trialdef.eventtype = '?';<br>
ft_definetrial(cfg);<u></u><u></u></p>
