MRXCAT with ERIC: extra-dimensional respiration with inflow of contrast

Required MATLAB toolboxes:

Additional toolboxes:

gpuSparse and nufft_3d from Mark Bydder. Note these are provided with the package but may need to be recompiled within MATLAB
nufft from Jeff Fessler and the Michigan Image Reconstruction Toolbox. Note future versions of the phantom will reduce the nufft redundancy.
bart, either on a linux system or using a Windows-based install. This code was tested using bart version 0.4.03 IMPORTANT: to run a compiled version of bart, update the app startupFcn within the mlapp file:
1. open MATLAB at the folder containing MRXCATwERIC.mlapp and double-click MRXCATwERIC.mlapp
2. Go to line 266 (startupFcn), and update the following lines of code to match your installation of bart
```
% explicitly add bart path, note will change depending on user
addpath(genpath('/PATH_TO_TOP_LEVEL_BART/'))
setenv('TOOLBOX_PATH','/PATH_TO_TOP_LEVEL_BART/bin')
```
imtool3d from Tanguy Duval - a really intuitive Matlab-based segmentation tool. Used for motion correction.

To start, open MATLAB at the folder containing MRXCATwERIC.mlapp and type:

MRXCATwERIC
