style='font-size:12.0pt'>Hi Andrea,<br>
<br>
Always happy to help. And thank you for helping us squashing bugs!<br>
<br>
Are you sure you are using the most recent fieldtrip version? There was a bug
several weeks ago that gave the warning (which used to be on line 214, but is
now on line 215) even when cfg.highlight was not numerical. (if it's numerical,
it is assumed cfg.highlight is used in the old way). If you have a version that
is newer than 19-12-2009 (date of previous bug fix), could you post the exact
code you use to call ft_topoplotER? This could give me a better idea on where
in the code the problem lies. Could you then also post the exact warning matlab
spits out? (if it's not a version problem, something complicated is going on
and all information is helpful). Thanks!<br>
<br>
Concerning ft_clusterplot, you're not actually supposed to use the highlighting
options directly. As clusterplot tries to determine the clustering
automatically, this could possibly interfere with it's normal functioning.
Thanks for pointing this out. I now added a check for these 'forbidden' options
and they will be removed automatically. The updated clusterplot will be
uploaded to the ftp-server somewhere late in the evening today. <br>
<br>
However, if you want to manage you're own clustering directly, you can also do
this using topoplotER/TFR. It might be a bit difficult, but you have to put all
the highlighting options in its own cell (including the ones that were already
in cells). There is 'hidden' documentation about this in topoplotER (you won't
see it with the help/doc command, but you will if you edit the function), you
can find it just below the normal documentation.<br>
I copy-pasted it here for easy reference:<br>
***********<br>
% It is possible to use multiple highlight-selections (e.g.: multiple
statistical clusters of channels)<br>
% To do this, all the content of the highlight-options (including
cfg.highlight) should be placed in a cell-array<br>
% (even if the normal content was already in a cell-array). Specific marker
settings (e.g. color, size) are defaulted when<br>
% not present. <br>
% Example (3 selections):<br>
% cfg.highlight
= {'labels', 'labels', 'numbers'}<br>
% cfg.highlightchannel = {{'MZF03','MZC01','MRT54'}, [1:5], 'C*'}<br>
% cfg.highlightsymbol = {'o',[],'+'}
% the empty option will be defaulted<br>
% cfg.highlightcolor = {'r',[0 0
1]}; % the missing option will be defaulted<br>
% cfg.highlightsize =
[];
% will be set to default, as will the missing
cfg.highlightfontsize<br>
***********<br>
<br>
Using these options you should be able to get the same individual plots
clusterplot can give you. If you do not want to see the other channels, set
cfg.marker = 'off';. On the use of the different routines, topoplotTFR is
identical to topoplotER, but is just present because of our present naming-scheme.
Clusterplot however, is a wrapper around topoplotER/TFR designed to quickly and
without much configuring plot your statistical clusters (which requires
statistics output as input). By using the 'hidden' options above, you can make
topoplotER/TFR do exactly the same as clusterplot, but then you can specify
your own clusters.<br>
<br>
<br>
We are currently looking into your question number 3, as it appears things go a
little deeper there. There are at least some situations where cfg.neighbours =
[] apparently doesn't work, but we are still figuring out why. For the moment,
a really ugly and time consuming workaround would be to make a for-loop over
single channels, but it would prevent the clustering over channels and should
provide (per channel) the exact same output as cfg.neighbours = [];<br>
<br>
<br>
I hope all of the above helps. Thanks for bringing these bugs to our attention!<br>
<br>
Kind regards,<br>
<br>
Roemer<br>
