[FieldTrip] Error -> ft_databrowser

[Elena Orekhova]

Hi
I encounted the same problem with ft_databrowser:

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

Error in ft_databrowser>redraw_cb (line 1159)
art = ft_fetch_data(opt.artdata, 'begsample', begsample, 'endsample',
endsample);

Error in ft_databrowser (line 535)
redraw_cb(h);
****************

The same data works OK with
[data] = ft_rejectvisual(cfg, data)

I have:
MacOS 10.6.8
MATLAB 7.13.0.564 (R2011b)

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

Elena

Hi Michael,


I have posted the question actually but I didn't hear any suggestions about it. The same error was posted yesterday by someone else.


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.


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.

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?
