rmincUtil.convertWorldToVoxel: Convert World to Voxel Coordinates

In jnikelski/rmincIO: Package for reading and writing MINC2 files

Description

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

Usage

    rmincUtil.convertWorldToVoxel(filename, worldCoords)

Arguments

filename	The name of a minc2 volume to be used to do the conversion to voxel space.
worldCoords	A 3 item vector of world coordinates in xyz order.

Details

Conversion requires access to a minc2 volume in order to enable the world to voxel mapping.

Value

A 3-item vector of 1-relative voxel coordinates.

Note

TODO: I really should be able to pass a MincInfo object and do the conversion within R code, without having to jump into the minc2 API.

Examples

## Not run: 
# set the xyz voxel coordinates
xyzCoords <- c(0, 0, 0)

# create a full pathname to the sample volumes
v305PET <- file.path(volDir, "average305_PET_t1_tal_lin.mnc")
print(v305PET)

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

## End(Not run)
