Greg, to make sure I understand correctly - it is not possible to make sure that the original link (https://www.slicer.org/slicerWiki/images/8/8d/MultiVolumeExplorer_Meysam_SNR-April2013-v4.pdf) is functional, correct?
The issue is that this link is referenced from external sources, such as this post: How to analyze DCE-MRI data. I can fix the link in that post manually, but there may be other places I am not aware of. Overall, it is rather important that the original links don’t die. Is redirecting an option?
