<br><font size=2 face="Arial">Hi Robert,</font>
<br>
<br><font size=2 face="Arial">In connection with your previous advice concerning
the eeglab2fieldtrip script, we came accross the following problem and
solution (see <i>script</i> below):</font>
<br>

fixprecision(EEG.data(:,:,index));</i></font>
<br><font size=2 color=#3f803f face="Arial"><i>% while the variable EEG.data
only contains the name of the variable and not the data</i></font>
<br><font size=2 color=#3f803f face="Arial"><i>% the next line assigns

<br><font size=2 face="Arial"><i>EEG.data = EEGDATA; </i></font>

<br>
<br><font size=2 face="Arial">I do still get the following warning after
running the above script:</font>

<br><font size=2 face="Arial"><i>In ConversionEEGDATA at 13</i></font>
<br>
<br><font size=2 face="Arial">Is this problematic or is this a standard
warning following conversion to Vision Analyzer?</font>
<br><font size=2 face="Arial">In addition, I was wondering where my trial
onset markers are written to? <i>Write_fcdc_data</i> only generates a .eeg
and a .hdr file, and not a .vmrk file. </font>
<br>
<br><font size=2 face="Arial">From your earlier emails I understood that
the datamatrix should be converted to <i>ntrials X nchans X nsamples </i>before
running <i>write_fcdc_data. </i> Currently my datamatrix consists
of <i>nchans X nsamples X ntrials.</i> <i> </i>Would you mind letting
me know how I can convert my datamatrix? Thanks a lot.</font>

Matlab 7.0.1 is an old version, released around end 2004. It was <br>
quickly superseeded with version 7.0.4 to fix some serious bugs. I <br>
reccommend people in general to work with the latest matlab versionm, <br>
which now is 7.4.<br>
<br>
You can fix your problem by changing the "matlabversion" function
<br>
which is included as subfunction inside the eeglab2fieldtrip <br>
function. Go to line 250 and replace the code there with the snippet <br>
below. I will make the same change in the release version.<br>
<br>
Robert<br>
----<br>
<br>
function [v] = matlabversion;<br>
s = ver('matlab');<br>
v = s.Version;<br>
if ischar(v)<br>
% try converting to a number<br>
n = str2num(v);<br>
if isempty(n)<br>
switch v<br>
case '6.5.1'<br>
n = 6.5; % this is accurate enough<br>
case '7.0.1'<br>
n = 7.0; % this is accurate enough<br>
case '7.0.4'<br>
n = 7.0; % this is accurate enough<br>
otherwise<br>
warning('cannot convert matlab version into a number');<br>
v = v;<br>
end<br>
end<br>
v = n;<br>
end<br>
