Hi Mahmoud,
<div class=""><br class="">
</div>
<div class="">I suggest that you start by reading the documentation on the website, e.g. the getting started section on
<a href="http://fieldtriptoolbox.org" class="">fieldtriptoolbox.org</a></div>
<div class="">Also, if you are a first time user of fieldtrip, I suggest you start reading in the data using the ft_preprocessing function, rather than ft_read_header/ft_read_data.</div>
<div class="">Also, the error you get is related to basic matlab syntax: the error says that you should use key-value pairs in the input. Perhaps if you google in the documentation of matlab you will find out what you could do to fix it.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>
<div class="">Jan-Mathijs</div>

<div class="">I have a .bdf file that I want to read in matlab usig ft_read_header()<br class="">
and ft_read_data().<br class="">
I have defined a list of channels as<br class="">
channels = ["CH1" , "CH2", "CH3", "CH4", "CH5"]<br class="">
<br class="">
When I try to read the header I get the following error:<br class="">
<br class="">
hdr = ft_read_header(filename, chanindx= channels);<br class="">
<br class="">
Error using ft_getopt<br class="">
the first input should contain key-value pairs<br class="">
<br class="">
Error in ft_read_header (line 183)<br class="">
headerformat = ft_getopt(varargin, 'headerformat');<br class="">
<br class="">
Can you please let me know what am I doing wrong? I read the help for<br class="">
ft_read_header() but couldn't figure it out.<br class="">
<br class="">
Thank you!<br class="">
Mahmoud<br class="">
