Subset points to be in the brain or in the VNC

Usage

banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

# S3 method for class '`NULL`'
banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

# S3 method for class 'neuron'
banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

# S3 method for class 'neuronlist'
banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

# S3 method for class 'matrix'
banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

# S3 method for class 'data.frame'
banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

# S3 method for class 'mesh3d'
banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

# S3 method for class 'hxsurf'
banc_decapitate(x, y.cut = 325000, invert = FALSE, ...)

Arguments

x

an object with 3d points to be subsetted, e.g. an xyz matrix, a neuron, neuronlist or a mesh3d object. Points must be in native BANC space, i.e. plottable inside banc.surf.

y.cut

Numeric, the Y-axis cut point, in nanometers, in BANC space, that separates the head from the neck and ventral nerve cord. For fitting to the MANC data set, a cut height of y.cut=5e05 seems good.

invert

if FALSE returns brain points, if TRUE returns VNC points.

...

Additional arguments passed to nlapply and then prune_vertices

Value

Remove points above or below the midsection of the neck connective of BANC.
