<p><span style="font-size: 11pt;">Good morning EEGlab team,</span></p>
<p><br style="font-size: 11pt;">
</p>
<p><span style="font-size: 11pt;">Last week, I sent an email regarding some issues I'm currently having with preclustering a dataset. While running preclustering on a 2x2 STUDY design, I got the error message "some datasets do not have ICA pairs look for NaN
values in STUDY.cluster.set..." message. I am sure though that I ran the ICA on condition-unseparated data before separating out the conditions, and I did not run ICA on different within-subject conditions. To this, Mr. Miyakoshi asked me if my 2x2 design
is all within subject conditions, and to check if all subjects have non-zero trials for all combinations of conditions. My study is a mixed design, with a within subject and between subject condition. I double checked the data entry to make sure I didn't leave
out any group numbers for any participants, and I'm positive that there is no missing data.
</span></p>

</p>
<p><span style="font-size: 11pt;">I'm not sure if this helps diagnosing the problem, but if I choose to precluster based on scalp maps or ERSPs alone, an error pops up stating that "Subscript indices must either be real positive integers or logicals." This
is the first time I've encountered this error when preclustering as well, and it happens at the same point in processing regardless of which dataset was present (I thought it may have been a problem with a specific participant dataset, removed said participant,
error just transferred to the participant right before it).</span></p>
<p><br style="font-size: 11pt;">
</p>
<p><span style="font-size: 11pt;">Thanks in advance for any help,</span></p>
