rmincUtil.convertVoxelToWorld: Convert Voxel to World Coordinates
In jnikelski/rmincIO: Package for reading and writing MINC2 files

Description Usage Arguments Details Value Author(s) See Also Examples

Converts 1-relative 3 dimensional ijk (voxel) coordinates into xyz (world) coordinates.

1	rmincUtil.convertVoxelToWorld(filename, voxCoords)

`filename`	The name of a minc2 volume to be used to do the conversion to world space.
`voxCoords`	A 3 item vector of 1-relative voxel coordinates.

I believe that all coordinates are in xyz order. I am pretty sure that this would not work with a 4D volume, but have not yet come up with a use-case, given that no 4D internal structures exist. Perhaps, reading a frame from a 4D volume, and then wanting to do a coordinate conversion. Hmmmmm, must ponder.

A 3-item vector of world coordinates.

# convert and show it
xyzCoords <- rmincUtil.convertVoxelToWorld(v305PET, ijkCoords)
