Hi all,<br><br>I have 64-channel data in a STUDY design -- when I've precomputed ERSP values via the GUI, I have no problem plotting the scalp maps for all electrodes. Recently, I precomputed the values with this code:<br>
<br>[STUDY, ALLEEG] = std_checkset(STUDY, ALLEEG);<br>[STUDY ALLEEG] = std_precomp(STUDY, ALLEEG, {},'allcomps','on','recompute','on','ersp','on', 'erspparams', {'cycles' [3 0.5] 'baseline' -5100 'freqscale' 'linear' 'tlimits' [-5300 2000] 'timesout' 600 'freqs' [3 30] 'nfreqs' 56 },'itc','on')<br>
<br>The ERSP maps for individual electrodes come out fine -- but when I try to plot the scalp map with all 64 electrodes, I get the following error: <br><br>Reading all ERSP data:Warning: Channel "cp4" and maybe others was not<br>
found in pre-computed data file<br>> In std_chaninds at 54<br> In std_readfile at 134<br> In std_readersp at 214<br> In std_erspplot at 180<br> In pop_chanplot at 303<br> In inputgui at 182<br> In pop_chanplot at 269<br>
??? In an assignment A(:) = B, the number of elements in A and B<br>must be the same.<br><br><br><br><br>When I try to plot electrodes like CP4 individually, it works just fine -- but when I try to do the scalp map, it seems that several electrodes are not reading properly. I can plot a few electrodes (I tried plotting 5 posterior-central electrodes and the localized map came out fine), but it seems several electrodes aren't reading. What am I missing?<br>
Thanks so much,<br>Pete<br>
