Run a loop on struct field

Hi

I am running a statistical analysis. I need to run the analysis multiple times for 6 different 'sensortypes'. This data is stored in a 2x1 struct with two fields called S. The data to be inputted is in the secomd field 'ROI_Sig'. Can anyone help with getting the loop to run in the script below?

for i = 1:length(S)
ROIData = S(i).ROI_Sig;
sFiles = bst_process('CallProcess', 'process_test_permutation2', sFiles5 sFiles6, ...
    'sensortypes',    ROIData, ...
end

The script runs correctly if I delete the loop and replace i with any value 1-6 in the line ROIData = S(i).ROI_Sig;

Hi,

You can use the below mentioned command to get a string array of all the fields in a struct s.

fields = string(fieldnames(s))

Refer to the doc link belowfor more details

Hi

Thank you for your reply. It is not the fieldname that I want to enter. It is the data within the field. Please see structure below. I want to make a loop to input each of the 6 rows from field ROI_Sig

S =

6×1 struct array with fields:

Region

ROI_Sig

ROI_Sig =

6×1 cell array

{'91, 92, 95, 96, 103'}

{'61, 67, 73, 74' }

{'113, 114' }

{'32, 34' }

{'127' }

{'41' }
