<br>
> I don’t know where I’ve got it wrong. Is there an obvious error I have made?<br>
<br>
I can't answer to this question. I also want someone to take a look at my groupSIFT code to guarantee there is no error.<br>
<br>
> I wonder if the way EEGLAB calculates things when producing scalp maps is different from the script I have, and if you might know of a way that I could check this? Can I access the data that is used to create the scalp maps?<o:p></o:p></p>

<p class="MsoNormal">Yes, you can use a debug mode in Matlab. Open one of the functions being used to generate the figure, put a red circle on the left column of the edit window, then run the code. The process will stop there, so you can trace the process line
by line. It's a basic technique so if you haven't tried it yet, I recommend you challenge it this time!<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I have 20 epoched datasets from 10 different subjects – 2 datasets per subject as there were 2 different conditions. I created averaged scalp maps (for all 10 subjects together,
for all channels) in the alpha range (8-12Hz) using the ‘Study/Precompute channel measures’ and ‘Study/Plot channel measures’ functions. I used 10 EEGLAB ‘.set’ files for one condition and another 10 for a different condition.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">When I ran the ‘Precompute channel measures routine’, I used these parameters: 'cycles', [3 0.5], 'baseline', [-3500 -1500], 'freqs', [2 60], 'alpha', 0.05, 'ntimesout', 400, 'padratio',1.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I then used ‘Plot channel measures’, using ‘8 12’ (8-12Hz) as the frequency parameter and did this repeatedly for 100ms time windows to see what is happening from -1000ms before

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I then wanted to plot ERSP over time for a select number of channels (as visually identified using the scalp maps – those with strong ERD/ERS ), so I used a function created in
MatLab that uses the ‘newtimef’ function, which creates the ‘ersp_sig’ variable containing significant ERSP. ‘ersp_sig’ is a 3-element vector – ersp_sig(a,b,c) where ‘a’ is frequency,’b’ is time points (400 per epoch), and ‘c’ is channels (35 in this case).<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">When I look at the plots, they don’t quite match what I see on the scalp maps. For example when I plot FC2, CP3 and CP4 together, my plots show that CP4 is activated before FC2
and a with a greater value, which is not what I see on the scalp maps – FC2 has a dark blue ‘patch’ (strong ERD) whilst CP4 is green – so I was expecting to see this reflected on the plot.<o:p></o:p></p>

<p class="m4686952079170469228msoplaintext">I don’t know where I’ve got it wrong. Is there an obvious error I have made? I wonder if the way EEGLAB calculates things when producing scalp maps is different from the script I have, and if you might know of a way
that I could check this? Can I access the data that is used to create the scalp maps?<o:p></o:p></p>
