Hi Pélagie,
<div class=""><br class="">
</div>
<div class="">As the error indicates, the data object that goes into ft_connectivityanalysis is not according to the function’s expectations.</div>
<div class=""><br class="">
</div>
<div class="">In general, data objects need to be according to FieldTrip’s definition, and using a low-level reading function, such as edfread in your example, returns only a matrix, and not the associated metadata. If you want the data properly formatted,
you should use ft_preprocessing.</div>
<div class=""><br class="">
</div>
<div class="">e.g.:</div>
<div class="">cfg = [];</div>
<div class="">cfg.dataset = ’s01.edf’;</div>
<div class="">data = ft_preprocessing(cfg);</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Next, if you want to compute the phase locking value (as is suggested by your call to ft_connectivityanalysis), you should first transform your epoched (!) time-domain data into the frequency domain by means of ft_freqanalysis.</div>
<div class=""><br class="">
</div>
<div class="">Note that there’s a wealth of tutorial and getting started documentation on the website:
<a href="http://www.fieldtriptoolbox.org" class="">www.fieldtriptoolbox.org</a>, which should get you started.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>

<div class="">Good morning their all.</div>
<div class=""><br class="">
</div>
<div class="">i run ft_connectivityanalysis.m script with the following configuration :</div>
<div class="">[data, header] = edfread("s01.edf")</div>
<div class="">freq = 250</div>
<div class="">cfg = [];</div>
<div class="">cfg.method = 'plv';</div>
<div class="">stat = ft_connectivityanalysis(cfg, data)</div>
<div class=""><br class="">
</div>
<div class="">and i get the following error:</div>
<div class="">Error using ft_checkdata (line 529)</div>
<div class="">This function requires 'freqmvar', 'freq' or 'source' data as input, see ft_datatype_freq or ft_datatype_source.</div>

<div class="">Error in ft_connectivityanalysis (line 271)</div>
<div class="">data = ft_checkdata(data, 'datatype', {'freqmvar' 'freq' 'source'});</div>
<div class="">need your help please.</div>
