Hey Russ,
<div class="">I saw your message come by on the discussion list. Apparently, nobody felt inclined yet to respond :(. </div>
<div class="">Is there a reason why you read in the data with an old version of fieldtrip? I think there’s a backward compatibility clash, which is most likely due to the more fancy way in which sensors are defined these days. It could be that things are resolved
if you upgrade your full analysis pipeline to a recent FT-version. Yet, I suspect an ‘adder under the grass’, as the Dutch saying goes…</div>
<div class=""><br class="">
</div>
<div class="">Best,</div>
<div class="">JM</div>

</div>
<div class="">PS: please do keep sending off questions to the list. The fact that nobody responds is usually not due to any lack of competence on your side, but is probably mainly due to everybody to be too busy with their own chores.</div>

understand that if due to my past emails on the discussion list (and their lack of competence), my questions are no longer sent out. Alternatively, I was wondering if I should have sent this email to the bug tracker (though again I am not sure if it is actually
a bug, or again my incompetence). I would really appreciate a confirmation, as I'm am currently held at my current step.</font></div>

Subject: possible bug when using old neuromas data with newer fieldtrip version<br class="">
To: FieldTrip discussion list <<a href="mailto:fieldtrip@science.ru.nl" class="">fieldtrip@science.ru.nl</a>><br class="">

<div style="word-wrap:break-word" class="">Hi All,
<div class=""><br class="">
</div>
<div class="">Sorry to bother you all, but I was wondering if I may have found a possible bug. If so, I’ll submit a request to the bugzilla subsection. I am not completely sure the issue is not my own incompetence though. The error occurs when using a neuromag
dataset that was read in with an old fieldtrip version (i.e. from 2015), and having it undergo ft_artifact_zvalue from a newer version of fieldtrip. </div>
<div class=""><br class="">
</div>
<div class="">In short, I use the following code:</div>

<div class="">When I run this code in a 2015 version of fieldtrip, it works fine (without any error). On the other hand, in the 2016 version of fieldtrip I have (as well as in the latest version which I downloaded this weekend), I get the following error:</div>
