Development for dcmstack and nibabel is still an ongoing process. However, I have some very basic functionality for conversion of enhanced structural and functional dicoms (mprage, rest, nbacks). However, I cannot ensure that the quality (i.e. calculations for Q form, S form...etc.) are correct!!!
Show command-line usage of the tool. ex:
Run dcmstack on the folder containing the dicom.
This code is temporarily in my own repository. The easiest way to download these may be as the zip file if you don't already have git installed.
You will need to have numpy and pydicom installed. Once you unzip these, you will need to install by going into each folder the packages are located in and enter "sudo python ./setup.py install". Of course, you need sudo powers for this. Also, it might be a better idea to install this in a virtual environment.
