<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Xiao,
<div><br>
</div>
<div>Maxfilter is a preprocessing step / software package for data coming from MEG systems by Elekta (fif format) (see <a href="http://www.megwiki.org/images/a/aa/MaxFilter-2.0.pdf" target="_blank">http://www.megwiki.org/images/a/aa/MaxFilter-2.0.pdf</a> for
a description).</div>
<div><br>
</div>
<div>In short you need to run your data through the Maxfilter software (which should have been provided by Elekta) before you can do anything with it. </div>

<div dir="ltr">Dear all:
<div>I use the ''ft_read_data'' code read .fif file by fieldtrip <br>
</div>
<div style=""><span style="color:rgb(0,0,0)">I get the following error message:</span></div>
<div style="">
<div>''Maxshield data has not had maxfilter applied to it - cannot be read by fieldtrip. Apply Neuromag maxfilter before converting to fieldtrip format.''</div>
<div><br>
</div>
<div>What should I do or Is there some Matlab codes to read .fif file ? </div>
<div><br>
</div>
