  "Description": "Provides very fast read and write access to images stored\nin the NIfTI-1, NIfTI-2 and ANALYZE-7.5 formats, with seamless\nsynchronisation of in-memory image objects between compiled C\nand interpreted R code. Also provides a simple image viewer,\nand a C/C++ API that can be used by other packages. Not to be\nconfused with 'RNiftyReg', which performs image registration\nand applies spatial transformations.",
