Hi, I have data file with physiology neuronal recording from 6 diffrent channels. I an plotting average cells response for each channel and sublot them in from 1:6. I am attaching figure here. But now I need subplot channels in a given order. For example ch = [6 4 2 1 3 5] Can anyone help? Many thanks Helen

for ch = [1 2 3 4 5 6]   
  subplot(2,6,ch); 
  concatenated_data = [];
  concatenated_data = [concatenated_data, mean(chn_data{ch},2)];
  plot((concatenated_data(20:end)),'-','DisplayName',channel_names, 'LineWidth', 3,'color', ([0 .0 .0]));
  ylim([ymin ymax])
end

Why can't you just substitute [6 4 2 1 3 5] for [1 2 3 4 5 6] in the loop index array?

It would be "more better" to write it so you could just walk through any desired sequence by setting that sequence vector and not have to actually modify the code, but for a "once-only" use the specific data array is the simplest.

Below modification will make the subplot in the order presented in the ch_order variable.

ch_order = [6 4 2 1 3 5];
for i = 1:length(ch_order)  
  ch = ch_order(i);
  subplot(2,6,i); 
  concatenated_data = [];
  concatenated_data = [concatenated_data, mean(chn_data{ch},2)];
  plot((concatenated_data(20:end)),'-','DisplayName',channel_names, 'LineWidth', 3,'color', ([0 .0 .0]));
  ylim([ymin ymax])
end
