In the below chunk of code, how can i save 'Current_file' variable after every trial, so that it stores 70 values for each of the 70 trials. There are total 70 number of trials and 161 images in Manipulable folder. Kindly refer to the full code attached here. Any help would be highly appreciated. Thank You.
folder ='F:\Ankit\2nd Study_Jan_2023\Manipulable_objects'
manipulable_image = dir(fullfile(folder, '/*.bmp'))
as = numel(manipulable_image);
imageseq = randperm(as);
for i=1:as
idx =imageseq(i);
img = imread(fullfile(folder,manipulable_image(idx).name));
Current_file = fullfile(folder,manipulable_image(idx).name);
end

"In your code------ variable 'T' is storing 70 random images if the value of 'k' is 70 , right ?"
It stores the filenames in T, not the images.
If you make k==70 then RANDPERM will randomly select 70 of the images from that folder.
"out of these 70 images stored in T, which of the image is presented on which of the trial (for i_trial =1:70)."
I have no idea, becase nowhere in your question do you explain how a "trial" is represented or indicated or encoded.

You can use save Current_file variable after it completetly created with save(filename,variable) function.
And also you can use it with eval function to save with variable variables names like Current_file_iter1,Current_file_iter2,Current_file_iter3 ....
For this use
for i=1:i_trial
%%%%%%
%%%%%%
Current_file = fullfile(folder,manipulable_image(idx).name);
filename=sprintf('Current_file_iter%d',i_trial);
save(filename,"Current_file");
end

You can use like that.
If you want to save in every iteration you can use like that. But if you want to save after all iterations completed. You can use a struct like;
folder ='F:\Ankit\2nd Study_Jan_2023\Manipulable_objects'
manipulable_image = dir(fullfile(folder, '/*.bmp'))
as = numel(manipulable_image);
imageseq = randperm(as);
for i=1:as
idx =imageseq(i);
img = imread(fullfile(folder,manipulable_image(idx).name));
Current_file{i,1} = fullfile(folder,manipulable_image(idx).name); %%% this is the code I suggest
end
save(Current_file,"Current_file"); %%% this is the code I suggest
