During preprocessing I lost some channels which I got back through ft_channelrepair after which the channel order changed per subject. I realigned the channel order and the associated data structure of each subject to one reference order after which the topoplots look completely different. They look even worse than before realignment. Anybody got a clue where the confusion arises? Attached a script and two data files, one with reference data and one with the to be aligned data.

Created attachment 292 data with chan reference and to be aligned data

I'm gonna have a look and see whether it's a quick fix

try doing: nERPdata_nD_left{isubject}.avg(loc,:) = ERPdata_nD_left{isubject}.avg(:,:); % realign data to ref channel order instead then it works fine

Stephen thinks that it still does not work. He is going to provide a snippet of code and some data so that we can reproduce and fix.

is this still relevant? if not, close please

Changing channel order by shuffling channels does not result in different topo/multiplots. This bug was possibly related to bug 1986.
