<div class="moz-cite-prefix">Hi Erik,<br>
wow, I really wouldn't have thought this could work ... but it
did! It resulted in a reduction of the file size from 4.6 GB down
to 9 MB (for the result of a statistical cluster permutation test).<br>
<br>
I still have a brain with a very dark color, though. Does anyone
know how to get rid of that?<br>
Why would these things change without an obvious reason?<br>
<br>
Thanks for your help, Eric!!<br>
All the best,<br>
Jens<br>

<div>Hi Jens,<br>

The problem might be that the cfg.previous-structure is
becoming quite large. Try to clear this before plotting the
data, like:<br>
</div>
<div>data.cfg.previous = [];<br>
<br>
</div>
<div>This is especially helpful when plotting grandaverage-data.
(I've seen cases in which the size went from 13 GB to 150 MB
just by clearing the cfg.previous)<br>

fieldtrip community,<br>
I encountered a weird problem. Lately, my source plots
started to have<br>
huge file sizes when I save them as figures (.fig). This
applies to both<br>
slice and surface plots. Surface plots used to have around
3-7 MB, now<br>
they have around 220 MB or even > 4 GB (ie. almost the
size of the<br>
plotted data set). They also look slightly different now,
with the<br>
surface being way darker than before. Slice plots look the
same but are<br>
also larger than before.<br>
<br>
The problem seems to be in the plotting process itself
(not the<br>
beamforming). When I plot older source localizations
(which by the way<br>
have the same file size, fields, and basic properties as
newer ones) the<br>
problem is still there.<br>
<br>
The code I am using for plotting did (to the best of my
knowledge) not<br>
change at all:<br>
cfg = [];<br>
cfg.method = 'surface';<br>
cfg.funparameter = 'avg.pow';<br>
cfg.maskparameter = cfg.funparameter;<br>
cfg.funcolormap = 'jet';<br>
cfg.projmethod = 'nearest';<br>
cfg.surfdownsample = 5;<br>
ft_sourceplot(cfg,data)<br>
<br>
I thought it may be a change in fieldtrip so I reverted my
ft_sourceplot<br>
to an older version but that did not help. I also used an
older Matlab<br>
version (currently I use 2013b but I also tried 2013a) and
another<br>
computer (Windows and Unix). In all cases I used opengl as
the renderer.<br>
<br>
I am sure it is something very simple and I'm just too
blind to see it.<br>
Any suggestions?<br>
<br>
Thanks a lot for your help,<br>
Jens<br>
