Create 'sEEG' shaft geometry prototype — seeg

Intended for creating/editing geometry prototype, please see load_prototype to load existing prototype

Usage

seeg_prototype(
  type,
  center_position,
  contact_widths,
  diameter = 1,
  channel_order = seq_along(center_position),
  fix_contact = 1,
  overall_length = 200,
  description = NULL,
  dry_run = FALSE,
  default_interpolation = NULL,
  overwrite = FALSE
)

Arguments

type: type string and unique identifier of the prototype
center_position: numerical vector, contact center positions
contact_widths: numerical vector or length of one, width or widths of the contacts
diameter: probe diameter
channel_order: the channel order of the contacts; default is a sequence along the number
fix_contact: NULL or integer in channel_order, indicating which contact is the most important and should be fixed during the localization, default is 1 (inner-most target contact)
overall_length: probe length, default is 200
description: prototype description
dry_run: whether not to save the prototype configurations
default_interpolation: default interpolation string for electrode localization
overwrite: whether to overwrite existing configuration file; default is false, which throws a warning when duplicated

Value

A electrode shaft geometry prototype; the configuration file is saved to 'RAVE' 3rd-party repository.

Examples

probe_head <- 2
n_contacts <- 12
width <- 2.41
contact_spacing <- 5
overall_length <- 400
diameter <- 1.12

contacts <- probe_head + width / 2 + 0:(n_contacts-1) * contact_spacing
proto <- seeg_prototype(
  type = "AdTech-sEEG-SD12R-SP05X-000",
  description = c(
    "AdTech sEEG - 12 contacts",
    "Contact length   : 2.41 mm",
    "Central spacing  : 5    mm",
    "Tip size         : 2    mm",
    "Diameter         : 1.12 mm"
  ),
  center_position = contacts,
  contact_widths = width,
  diameter = diameter,
  overall_length = overall_length,
  dry_run = TRUE
)
