tacmagic: Positron Emission Tomography Time-Activity Curve Analysis

Description Usage Arguments Details Value See Also Examples

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.

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)

`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

See load_tac() for specifics.

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

# 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="")
