matlab - Rename dicom images -


i have 110 ct dicom images, , names randoms, when display them using dicom viewer, displayed randomly. trying rename these dicom images according image number (0020,0013) or slice location (0020,1041). have started write script 

image_list=dir('*.dcm');  i=1:25     img=dicomread(image_list(i).name);     imghdr = dicominfo(image_list(i).name);  dicomwrite(img, ['t' num2str(i) '.dcm'], imghdr,'createmode','copy') end

but don't know how tell check instancenumber , use in new name ?

the instancenumber accessible element of dicominfo output struct:

instancenumber = imghdr.instancenumber;

and construct filename using sprintf

outputfilename = sprintf('t%04d', instancenumber);

there many formats sprintf mirroring c++'s printf, ones used above print integer (the 'd') 4 digits (the '4'), 0 padded (the '0'). automatic sorting file managers. if need different format check docs here.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
