I have a very weird problem.

I open a DicomFile and save it without changing a thing, but when I look at the dcm in synedra view, they are different.

The original files goes from -4096 to 4096 but the save file only from 0 to 4096. I then tried to stretch the file by myself i.o.:

x = (2.*x-4096);

But this was also not working, dicomwrite cuts the values below 0...

dinfo = dicominfo('testDicom.dcm');

x = dicomread(dinfo);

dicomwrite(x, 'testDicom2.dcm', dinfo)

Any ideas?

Best Ingo

Okay, I solved the problem!

If I would have read the manual carefully I have to use the option ( 'CreateMode', 'copy' ):

dicomwrite(x, 'testDicom2.dcm', dinfo 'CreateMode', 'copy');

Thanks for your help again and best wishes
