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

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="")
