<div><br>
</div>
<div>I am new to feildtrip and I wanted to start analyzing my data using the field trip. I have 64 channels of EEG recordings and I tried to convert my data to fieldtrip cell type to be able to browse the data using ft_databrowser, but there is a problem and
I am not sure if it because of my data format or some other problems. I have reported the error and the structure of my data in the following.</div>
<div>Please do me a favor and check my data and help me with this issue.</div>
<div><br>
</div>
<div>Regards,</div>
<div>Maryam <br>
