<div class="">Hi Anne,</div>
<div class=""><br class="">
</div>
<div class="">I believe that this issue has been fixed a while ago.</div>
<div class=""><br class="">
</div>
<div class="">If I check the latest version of the code on <a href="https://github.com/fieldtrip/fieldtrip/blob/master/ft_prepare_neighbours.m" class="">
https://github.com/fieldtrip/fieldtrip/blob/master/ft_prepare_neighbours.m</a> it looks fine to me.</div>
<div class="">In particular, in line 94 the variable hasdata is explicitly defined.</div>
<div class=""><br class="">
</div>
<div class="">Could you please upgrade to the most recent version of Fieldtrip and try again?</div>
<div class=""><br class="">

<div class="">Best wishes,</div>

<div class=""><br class="">
</div>
<div class="">I'm doing permutation tests, for which I wrote a script a while ago, which worked nicely back then, but now gives me the following error when I run the ft_prepare_neighbours function: </div>
<div class=""><br class="">
</div>
<div class="">Error: Undefined function or variable 'hasdata'.<br class="">
</div>
<div class=""><br class="">
</div>
<div class="">I'm assuming that this means that the function does not properly access the data structure that I give it. I just don't know why and how to fix it, given that the very same script worked about half a year ago. I have updated my version to Matlab
2016a in the meantime, but all other things stayed the same. </div>
<div class=""><br class="">
</div>
<div class="">To give you a better idea, here is what my data looks like for one participant:</div>
<div class=""><br class="">
</div>
<div class="">
<div class="">Data{1}</div>
<div class="">avg: [34x600 double]</div>
<div class="">time: [1x600 double]</div>
<div class="">fsample: '500'</div>
<div class="">label: {34x1 cell}</div>
<div class="">dimord: 'chan_time'</div>
<div class="">dof: [34x600 double]</div>
<div class="">var: [34x600 double]</div>
</div>
<div class=""><br class="">
</div>
<div class="">I have data for 21 participants. </div>
<div class=""><br class="">
</div>
<div class="">Here is the part of the script up until the prepare neighbours function, Correct and Incorrect being the respective datasets for my two conditions:</div>
<div class=""><br class="">
</div>
<div class="">
<p class="">cfg = [];</p>
<p class="">cfg.channel = <span class="">'all'</span>;</p>
<p class="">cfg.latency = <span class="">'all'</span>;</p>
<p class="">cfg.parameter = <span class="">'avg'</span>;</p>
<div class=""> <br class="webkit-block-placeholder">
</div>
<p class="">% prepare neighbouring channels</p>
<p class="">cfg_neighb = [];</p>
<p class=""><span class="">cfg_neighb.method = </span><span class="">'triangulation'</span><span class="">; </span></p>
<p class="">cfg_neighb.channel = <span class="">'all'</span>;</p>
<p class="">cfg_neighb.feedback = <span class="">'yes'</span>;</p>
<p class="">cfg_neighb.layout = <span class="">'easycapCustomMSC.mat'</span>; </p>
<p class=""><span class="">cfg_neighb.neighbourdist = 0.2; </span></p>
<p class="">neighbours = ft_prepare_neighbours(cfg_neighb, Correct{1});</p>
<p class=""><br class="">

<p class="">I hope this is enough information to help me out. </p>
