How to use regexp in a cell array whose cells may contain cell entries

Hello,

Ι have the following cell array

I want to use -regexp to find where 'Carbon fixation' is written.

I would use: regexp(model.subSystems,'Carbon fixation');

The problem is that some cells contain cell entries, so this is a problem.

I want to find where (and especially in which row) 'Carbon fixation' is written, in any cell in any cell entry.

Can anyone help me? Thank you!

@Ioannis Vourvachakis: please upload the cell array in a .mat file by clicking the paperclip button.

This is it

I want to know where that text is appeared (anywhere), and I mean in which row of this array.

All of them do:

>> all(cellfun(@iscell,model.subSystems))
ans =
logical

Your data:

S = load('model.subSystems.mat');
model = S.model;

Getting indices of nested cells which contain the requested text:

fnh = @(c)any(~cellfun(@isempty,regexpi(c,'Carbon fixation')));
idx = cellfun(fnh,model.subSystems);

Checking:

find(idx)

ans = 35×1

193 194 195 196 197 198 199 200 201 202

model.subSystems{193}{:}

ans = 'Carbon fixation'
