Handle raw and nm calibrated banc coordinates

banc_voxdims returns the image voxel dimensions which are normally used to scale between raw and nm coordinates.

Usage

banc_voxdims(url = choose_banc(set = FALSE)[["fafbseg.sampleurl"]])

banc_nm2raw(x, vd = banc_voxdims())

banc_raw2nm(x, vd = banc_voxdims())

Arguments

url: Optional neuroglancer URL containing voxel size. Defaults to getOption("fafbseg.sampleurl") as set by choose_banc.
x: 3D coordinates in any form compatible with xyzmatrix
vd: The voxel dimensions in nm. Expert use only. Normally found automatically.

Value

For banc_voxdims A 3-vector

for banc_raw2nm and banc_nm2raw an Nx3 matrix of coordinates

Details

relies on nat >= 1.10.4
