%description
QUIT (QUantitative Imaging Tools) is a collection of programs for processing
quantitative MRI data, including DESPOT, relaxometry, magnetization transfer,
perfusion, susceptibility mapping, and more. All tools are accessed via the
single 'qi' command with subcommands, similar to git or bart.

QUIT processes NIfTI format neuroimaging files and accepts sequence parameters
via JSON input.
