Hi Daniel,
<div class=""><br class="">
</div>
<div class="">This is a bit complicated, because it depends on how you structured your data file and whether the different base images were presented to the same participants or to different ones. Anyway, you have made a mistake in your code. Your reference
baseimage as argument to the call to batchGenerateCI2IFC but you define the two baseimages as separate variables earlier (baseimage1, baseimage2). For now, the easiest option is to only refer to one as baseimage, and make sure you then only supply the subset
of responsedata that applies to that specific base image.</div>

Hello all,
<div class=""><br class="">
</div>
<div class="">I’m attempting to analyze the data for a RC study using two base images. When I run the generateCI2IFC command, I get the following error:</div>
<div class=""><br class="">
</div>
<div class="">Error in colMeans(weighted):</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>‘x’ must be an array of at least two dimensions</div>
<div class=""><br class="">
</div>
<div class="">In my response data file I have four columns: 1) Subject_nbr (numerical), 2) Face (stim number presented), 3) Sex (gender of the stimulus presented), and 4) correct (1 or -1 based off of participant response).</div>
<div class=""><br class="">
</div>
<div class="">Full script reproduced below. Thanks in advance for your help!</div>
