Read and Write NIfTI Files

Tools for reading and writing NIfTI-1.1 (NII) files, including optimized voxelwise read/write operations and a simplified method to write dataframes to NII. Specification of the NIfTI-1.1 format can be found here < https://nifti.nimh.nih.gov/nifti-1>.

Tools for reading and writing NIfTI-1.1 (NII) files, including optimized voxelwise read/write operations and a simplified method to write dataframes to NII.

I/O operations in nifti.io are optimized to be very fast and require minimal RAM. GZipped NII files are not supported (due to inconsistent indexing into files). Specification of the NIfTI-1.1 format can be found here LINK.

These methods were developed to support freedom in statistical modelling that currently does not exist in standard neuroimage processing suites. If a statistical model can be deployed in R, then nifti.io can:

1. bring 3D and 4D neuroimaging data into R to be modelled with parallelization and efficient memory use in mind
2. and put statistical results back into brain-space for visualization, interpretation, and further analysis.
