Handle raw and nm calibrated Aedes coordinates

aedes_voxdims() returns image voxel dimensions used to scale between raw and nm coordinates.

Usage

aedes_voxdims(url = choose_aedes(set = FALSE)[["fafbseg.sampleurl"]])

aedes_nm2raw(x, vd = aedes_voxdims())

aedes_raw2nm(x, vd = aedes_voxdims())

Arguments

url: Optional Neuroglancer URL containing voxel size metadata. Defaults to the active Aedes sample URL.
x: 3D coordinates in any form compatible with nat::xyzmatrix().
vd: Voxel dimensions in nm. Advanced use; normally detected automatically.

Value

For aedes_voxdims(), a numeric 3-vector.

For aedes_raw2nm() and aedes_nm2raw(), an N x 3 numeric matrix.

Examples

aedes_voxdims()

aedes_raw2nm(c(159144, 22192, 3560))
aedes_nm2raw(c(2546304, 355072, 160200))
} # }
