NIfTI support
From VoxBoWiki
VoxBo supports reading and writing 3D and 4D NIfTI-1.1 nii files as well as img/hdr pairs. The files may or may not be compressed with gzip.
VoxBo makes an attempt to preserve the NIfTI headers when dealing with files created elsewhere, but does not copy the extended header. VoxBo makes no effort to set the qform and sform meaningfully, but will try to preserve it when it's been set by external software.
