I have 30 imagedatastores stored in a cell arrays bigImgDS{30,1}.
Now I want select one datastore in cell array as test and combine all other as train in one iteration of loop. But it doesnt allow me to do that
N = numel(bigImgDS)
for i =1:N
test = Big_ImgDs{i,1};
train = Big_ImgDs{[1:end ~=i],1}
end

Hi Mudit,
Use the following code for looping in the cell array
for i =1:N
test = Big_ImgDs{i};
train = Big_ImgDs;
train(i)=[];
end

I tried that out Anmol. But Split ImageDatastore labels by proportions - MATLAB splitEachLabel (mathworks.com) doesnt work on combine. Thats the problem the combine datastore doesnt behave the same way as a Image datastore
