<p class="MsoNormal" style="margin-bottom:12.0pt">Dear all,<o:p></o:p></p>
<p>I suddenly found my ft_read_header function could not work and gave errors as bellow if I opened the matlab from terminal.
<o:p></o:p></p>
<p><o:p> </o:p></p>
<p class="MsoNormal" style="margin-bottom:12.0pt">>> hdr = ft_read_header('hyh_raw_trans_ref_tsss.fif');<br>
Transforming MEG channels according to the device to head transform from the data<br>
306 MEG channel locations transformed<br>
Error using ft_read_header<br>
Undefined function 'fiff_read_epochs' for input arguments of type 'char'.<br>
<br>
<o:p></o:p></p>
<p>But ft_read_header works when I open matlab directly clicking the desktop MATLAB icon. In both cases, I add fieldtrip folder to the path and execute the
<strong><span style="font-family:"Aptos",sans-serif"><a href="https://www.fieldtriptoolbox.org/reference/ft_defaults">ft_defaults</a></span></strong> function before I run ft_read_header.
<o:p></o:p></p>
<p>Can someone tell me the reason? <o:p></o:p></p>
