Parse a CATMAID URL to extract parameters including xyz location

catmaid_parse_url(x)

Arguments

x: One or more catmaid urls

Value

A data.frame containing parsed parameters. The columns will be named according to CATMAID's convention except for the x, y and z location (named as such rather than xp, yp, zp as returned by CATMAID).

Examples

u=paste0("https://neuropil.janelia.org/tracing/fafb/v12/?pid=1&zp=177100&",
  "yp=166068&xp=373086&tool=tracingtool&sid0=7&s0=1.000000")
catmaid_parse_url(u)
