Question Posted 09/09/24:
I'm trying to load a multi shell (b=0,500,1000,2000) diffusion sequence based on the ADNI4 protocol on our Siemens Skyra VE11C and I can't locate the appropriate diffusion direction file (.dvs). It seems like it should have 99 directions specified.

Hello,
We would like people to get the .dvs file(s) and loading instructions through LONI, but unfortunately they are hard to find. The URL is https://ida.loni.usc.edu/pages/access/studyData.jsp?categoryId=14&subCategoryId=45 , but just going to the URL directly will not work.
Instead, go to https://ida.loni.usc.edu
log in,
go to Projects -> ADNI -> Download -> Study Data.
Wait for the green sidebar to appear on the left.
Go to Imaging -> MR Image Acquisition.
Now you should see the ADNI 3 Diffusion Gradient Table information links for each manufacturer.
