Diffusion MRI/ PET Simulation

These data are designed to simulate diffusion-weighted images using Fibrefox, analytical PET simulation with ASIM, and PET image reconstruction with STIR. file description /MRI Fibers.fib: the ground-truth fiber tracks file from Tractography Challenge ISMRM 2015 Data bvals, bvecs: the encoding scheme files for DWI simulation (similar to HCP protocol) t1.mif: the fabricated T1 image dwi.mif: the example DWI file simulated /PET AAL_ROI_upsample: a template phantom file with 3 lesions asim_pipeline.sh: batch code for ASIM simulation AAL_ROI_noisy_2: normalised PET sinogram 1e+08 total count, ready to be reconstructed AAL_ROI_noisy.yaff: normalised PET sinogram 1e+07 total count, ready to be reconstructed AAL_ROI_noisy_2.yhdr: ASIM header file OSEM_m962,par hdr_E_m962.hs: header files for STIR reconstruction with OSMAPOSL
