<p class="MsoNormal">Hello<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I wonder if anybody could please offer some advice on altering the eeg_checkset code so that it doesn’t automatically treat files with one epoch as continuous. I think the issue is here:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In eeg_checkset line 182:<o:p></o:p></p>
<p class="MsoNormal">case 'epochconsist', % test epoch consistency<o:p></o:p></p>
<p class="MsoNormal"> % ----------------------<o:p></o:p></p>
<p class="MsoNormal"> res = 'no';<o:p></o:p></p>
<p class="MsoNormal"> datasettype = unique_bc( [ EEG.trials ] );<o:p></o:p></p>
<p class="MsoNormal"> if datasettype(1) == 1 & length(datasettype) == 1, return; %<o:p></o:p></p>
<p class="MsoNormal">continuous data<o:p></o:p></p>
<p class="MsoNormal"> elseif datasettype(1) == 1, return; %<o:p></o:p></p>
<p class="MsoNormal">continuous and epoch data<o:p></o:p></p>
<p class="MsoNormal"> end;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The code says that if there is only 1 epoch, the file is continuous. This means<o:p></o:p></p>
<p class="MsoNormal">that if I try to include this file in a study in which most files have several<o:p></o:p></p>
<p class="MsoNormal">epochs, it says there is no epoch consistency and there is an error when I try<o:p></o:p></p>
<p class="MsoNormal">to do FFT analysis. However, the nature of my analysis means there are many<o:p></o:p></p>
<p class="MsoNormal">files with only 1 epoch. (My epochs are spontaneous transients in EEG which<o:p></o:p></p>
<p class="MsoNormal">I've zeropadded to make the same duration/same number of data points. I've<o:p></o:p></p>
<p class="MsoNormal">split them up by topography so it's common that in 1 file there may be just one<o:p></o:p></p>
<p class="MsoNormal">with, for example, a right occipital topography.)<o:p></o:p></p>
