These scripts reproduce the experiments described in the article:
Rosenzweig S, Holme HCM, Uecker M, Simple Auto-Calibrated Gradient Delay Estimation From Few Spokes Using Radial Intersections (RING), Magn. Reson. Med. 2018, 10.1002/mrm.27506. [1,2]
For reconstruction we provide an adapted version of the Berkeley Advanced Reconstruction Toolbox (BART)  (commit 94ae49b).
In each folder the *.sh shell-scripts must be started. These scripts require BART .
The data can be viewed e.g. with 'view' or be loaded into Matlab or Python using the wrappers provided in BART subdirectories './matlab' and './python'
For the plots python  is used.
If you need further help to run the scripts, I am happy to help you: firstname.lastname@example.org
