In this task the perfusion analysis steps are encoded into an xml file as suggested by OSIPI in the publication "A community-endorsed open-source lexicon for contrast agent-based perfusion MRI: A consensus guidelines report from the ISMRM Open Science Initiative for Perfusion Imaging (OSIPI)" (https://pubmed.ncbi.nlm.nih.gov/37831600/).
The option to write out this xml file is added to the MR Perfusion DataFit and Generic Fitting View.
