<div dir="ltr"><div><div><div><div>Dear Makoto,<br></div>Thanks for your reply. Following your suggestion, I checked all the datasets closely. All datasets had adequate number of trials of each type. However, the EEG.event.type field in some datasets was a 'numeric' (double) in some while it was a 'character' in the other datasets. After converting all event type markers in the EEG.event.type field into 'character' values, the STUDY design was able to read and precompute the previuosly ignored datasets. Thanks for your lead. I am summarizing the issue below for others who may encounter a similar problem:<br>
</div><br>The problem: STUDY design failed to select and precompute all subjects assigned though each of the individual datasets on plotting was showing adequate number of trials for each epoch type (condition).<br></div>
<br>The 'diagnosis': The EEG.event.type field in some datasets was 'character' while in other datasets its was 'numeric'. The STUDY design was ignoring those datasets in which the the EEG.event.type field was a 'numeric'.<br>
<br></div>The solution: Using a matlab script, each event.type field in all of the datasets was checked and converted to 'character' format if it was 'numeric'. <br><div><br></div><div>(RESOLVED)<br><br><br>

Each of the subject datasets is epoched based on 4 event types. I have specified a type*group STUDY design in which I "Select all subjecsts". When I precompute ERSPs, everything runs without errors. HOWEVER, on completion of the analysis I see that not all subjects' ERSP data has been precomputed and the ERSP plots are based on only a subset of the subjects within each Group. On looking at the "Edit Study Design" dialog box, only some of the subjects datasets are highlighted when the study design is selected. Things do not change even if I attempt to edit the study design by selecting all subjects. All the subject datasets have been preprocessed using the same pipeline and have the same number of channels, event types etc. A similar analysis of data from another experiment on the same set of subjects with similar processing pipeleine runs without any issues. I would be grateful for any assistance in trouble shooting this situation. Thanks in advance!<br>
