MATLAB: Find in cell array

cell arrays

Hi all

I have 2 cell arrays.

one of them is my EEG bad channels and another is all EEG channels.

I want to find row numbers of the bad channels in my all EEG channels. For example, I have c4 in my bad channels and c4 in all channels file is 35.

and Fp2 is 3 in all channels. I want to do it by code. I've tried with:

idx = find(ismember(A,B))

but it works just when I put B in '' for instance:

   idx = find(ismember(all_channels,'C4')) %ismember is case sensitive

I've attached my .mat files.

would you please help me.

Hamed

ind = cellfun(@find,cellfun(@(c) strcmp(all_channels,c),bad_channels,'uni',0))

MATLAB: How to add channels to exclude while keeping the channels already excluded

If you want to add 46 to the bad channels, probably the easiest way is to ‘grow’ the vector:

bad_channel = [bad_channel; 46];

(This is not great programming practice. In some instances, it works best.)

MATLAB: Replace specific string in structure

This should do the trick:

%create part of your data structure as an example
EEG=struct;
EEG.event(1).type='11';EEG.event(1).latency=rand;
EEG.event(2).type='keypad1';EEG.event(2).latency=rand;
EEG.event(3).type='21';EEG.event(3).latency=rand;
EEG.event(4).type='31';EEG.event(4).latency=rand;
EEG.event(5).type='keypad1';EEG.event(5).latency=rand;
L=ismember({EEG.event.type},{'keypad1'});
[EEG.event(L).type]=deal('1');
