batch_load {tacmagic}

Load (+/- merge) ROIs for batch of participants

Description

For a vector of participant IDs and correspondingly named tac files, this loads the tac files. If roi_m = T, then can also merge ROIs into larger ROIs based on the optional parameters that follow.

Usage

batch_load(
  participants,
  dir = "",
  tac_file_suffix = ".tac",
  tac_format = "PMOD",
  roi_m = FALSE,
  PVC = NULL,
  vol_file_suffix = NULL,
  vol_format = NULL,
  merge = NULL,
  ROI_def = NULL,
  tracer_dose = NULL,
  dose_unit = NULL,
  weight_kg = NULL
)

Arguments

participants

A vector of participant IDs

dir

A directory and/or file name prefix for the tac/volume files

tac_file_suffix

How participant IDs corresponds to the TAC files

tac_format

Format of tac files provided: See load_tac()

roi_m

TRUE if you want to merge atomic ROIs into larger ROIs (and if not, the following parameters are not used)

PVC

For PVC, true where the data is stored as _C in same tac file

vol_file_suffix

How participant IDs correspond to volume files

vol_format

The file format that includes volumes: See load_vol()

merge

Passes value to tac_roi(); T to also incl. original atomic ROIs

ROI_def

Object that defines combined ROIs, see ROI_definitions.R

tracer_dose

optionally, a vector of tracer doses (in the same order as participants), for SUV

dose_unit

if tracer_dose is specified, note the unit (e.g "MBq")

weight_kg

optionally, a vector of participant weights in kg, for SUV

Details

See load_tac() for specifics.

Value

A list of data.frames, each is a participant's TACs

Examples

# For the working example, the participants are full filenames.
participants <- c(system.file("extdata", "AD06.tac", package="tacmagic"),
                  system.file("extdata", "AD07.tac", package="tacmagic"),
                  system.file("extdata", "AD08.tac", package="tacmagic"))

tacs <- batch_load(participants, tac_file_suffix="")
