PyASL: GUI, preclinical functionalities and batch mode

In previous roadmaps, we collected code to create PyASL, a Python library to preprocess ASL data (both preclinical and human brain data). PyASL not only enables users to compare different preprocessing pipelines, but its modular structure also allows users to mix and match functionalities from different established pipelines to best suit their needs. To facilitate its usage among non-experts, we aim to develop a GUI for this library and expand its functionalities.
