<p class="MsoNormal">In my study I have several conditions (A, B,C…) and the epochs get organized into categories based on response (e.g., Condition A-Correct, Condition A-Incorrect, Condition B-Correct, Condition B-Incorrect, and so on…). This results with
several single response epochs for certain categories. When I load this into STUDY it says “Epoch Consistency = no” and leads to matrix dimension errors for the ERSP.

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I have read through the Eeglablist and have found were several people want to analyze a single epoch as an epoch, not as continuous EEG - the EEGLAB default. The consistent response I have read is “ If there is one epoch, it cannot be recognized
as epoched”. My question is why? <u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">How does a single epoch from a single subject in a condition with other multiple epochs from other subjects, all with the same epoch length not meet the criteria of epoch consistency? I know that EEGLAB reads a single epoch as continuous,
but is there no way to change/override this assumption?<u></u><u></u></p>

<p class="MsoNormal">In my own naïve attempt to address this issue, I tried to make single epochs “seem” the same in the STUDY structure by copying and formatting the ALLEEG.event information over to the ALLEEG.epoch. This still leaves the issue of the ALLEEG.trials
=1. <u></u><u></u></p>
