<TITLE>BUG in ft_topoplotER (cfg.xlim) version 20100127</TITLE>

<P><FONT SIZE=2>Dear all,<BR>
<BR>
I wanted to report a bug in ft_topoplotER (Fieldtrip version 20100127), regarding the use of cfg.xlim. It doesn't seem to use cfg.xlim when you choose one, but just to use the 'maxmin'. When I average the data over xlim myself I get a completely different topoplot then when I use cfg.xlim for the same range. I wouldn't have known if I didn't need to average over xlim for other reasons.<BR>
<BR>
It seems to happen between lines 445 and 452. The data are selected for cfg.ylim and cfg.component but not for cfg.xlim. This changes the outlook on my data completely, and I think this could be important for all users of this version. Therefore I send it to the entire mailing list.<BR>
<BR>
I have changed it now to:<BR>
444 % make dat structure with one value for each channel<BR>
445 dat = getsubfield(data, cfg.zparam);<BR>
446 if ~isempty(cfg.yparam),<BR>
447 dat = dat(:, ymin:ymax, xmin:xmax);<BR>
448 dat = nanmean(nanmean(dat, 2), 3);<BR>
449 elseif ~isempty(cfg.component) | ~isempty(cfg.xlim);%this part Hanneke added<BR>
450 dat = dat(:, xmin:xmax);<BR>
451 dat = nanmean(dat, 2);<BR>
452 end<BR>
453<BR>
454 dat = dat(:);<BR>
<BR>
This helps for me and it is very important for me as well, my data looks meaningfull now!<BR>
<BR>
Best and good luck!<BR>
