MATLAB: How to crop multiple files

cropdicommaskmultiple

hello guys , worked on triangular mask cropping of a DICOM image , here is the code –
 clear all
 I=dicomread('four.dcm');
 I=uint16(I);
 g=imshow(I,[0 600]);
 axis on 
 [x,y]=ginput(3);
 h = impoly(gca, [x,y]);
 pos = wait(h);
 BW = createMask(h,g);
 BW=uint16(BW);
 J=I.*BW;
 figure,imshow(J,[0 600]);
I just want to perform this task on multiple DICOM images . used for loop but createMask is showing error about cell type data variables . what will be the approach ? please suggest me . Thank you

for i = 1:length(fileList)
 I=dicomread(fileList{i}); %fileList contains names of all dicom images
 I=uint16(I);
 g=imshow(I,[0 600]);
 axis on 
 [x,y]=ginput(3);
 h = impoly(gca, [x,y]);
 pos = wait(h);
 BW = createMask(h,g);
 BW=uint16(BW);
 J=I.*BW;
 figure,imshow(J,[0 600]);
end
