Hi Elena,<br>
<br>
most likely your data has trials with overlapping sample points.
Unfortunately, the databrowser does not support this, or to be more
specific ft_fetch_data does not support this. The reason for this is
that a specific segment in time is defined twice in your data, and
it is not clear what segment it is you would like to look at (due to
filter artifacts and other preprocessing steps, the data will most
likely have different values for the same sample points). For
non-continuous data (already preprocessed data), it should be able
to implement this nonetheless, but that's on our todo list. The best
way for now is to call ft_redefinetrial and cut out the overlapping
segments.<br>
<br>
You could also hack your way around this by removing
data.sampleinfo. FieldTrip will then make up arbitrary, meaningless
sample numbers. Keep in mind that we do not recommend this though.
There is no way that the reconstructed sample numbers can be traced
back to your original data! (well... if your programming skills are
reasonable enough, it is possible, but that requires some further
hacking, and a lot of effort). <br>
<br>
Best,<br>

I encounted the same problem with ft_databrowser:<br>

*************<br>
fetching artifacts... Error using ft_fetch_data (line 57)<br>
data does not contain a consistent trial definition, fetching

The same data works OK with <br>

<br>
I have:<br>

MATLAB 7.13.0.564 (R2011b)<br>

Matlab re-installation did not help in my case.<br>
I would be grateful for any tips.<br>

<div>Hi Michael,<br>
<br>
<br>
I have posted the question actually but I didn't hear any
suggestions about it. The same error was posted yesterday by
someone else. <br>
<br>
<br>
just to repeat what i have replied in the other post, i
tried many things to solve it (changed the code, run the
databrowser code line by line, updated fieldtrip version at
etc.), but none of them solved the problem. I started
getting the error after I tried using parallel processing
scripts in matlab. But as i said, i have no basis to say
that this caused the problem. So basically, i do not know
any scientific solution.<br>
<br>
<br>
But an old school method solved the problem in my case.
Simply i uninstalled and re-installed matlab. Never got the
error again. You may want to try this. I have no other
solution.<br>
<br>
<br>

</font>I am encountering a strange error
while i try to use ft_databrowser. The
error code is as below. I have never seen
this error earlier. I used ft_databrowser
many times and its only last 2 days that i
am getting the error. I downloaded a newer
version of fieldtrip (fieldtrip-20120130)
and used the newer version but still the
same error. Strangely, i dont get this
error when i tried with other computers
(same matlab version (R2010a), same
operating system (windows 7) on both
computers. Has anyone got this error
before? what may cause this error?</span></p>
