When you read in the files, it is usually not a guarantee they will come in "in order" from the smallest to largest z axis position. Use the sort function to fix this. You need to sort on the z position of the images, this should be the third element of the image position patient dicom tag.

So do this 1. Use dir to get names of all files in series 2. Write a for loop and read the files in using dicomread for the pixel data and dicominfo to get the z position from the third element of the image position patient element (some images also have a tag called slice location you can use) 3. Use the sort command to reorder the image once you finish reading them all in. Sort on the z position.

This will fix your issue. I've had the same problem when I started messing with dicom... ;)
