DAT.checkData: Create and check data file.

In DATforDCEMRI: Deconvolution Analysis Tool for Dynamic Contrast Enhanced MRI

Description

The user loads DCE-MRI data into R using pre-existing functions such as read.table; DAT.checkData then saves all data into a single RData file which can be analyzed using DAT.

Usage

DAT.checkData(file.name, vector.times, map.CC, mask.ROI,
vector.AIF, slice.start=1, slice.stop="not.specified")

Arguments

file.name	Specify a name for the file that will be generated.
vector.times	Vector of time points at which contrast agent concentrations are measured (should have units of seconds).
map.CC	Array of voxel-wise contrast agent concentrations.
mask.ROI	Array containing the predefined Region of Interest.
vector.AIF	Vector containing the Arterial Input Function.
slice.start	For multislice data files, a range of slices must be specified. Slice numbers less than slice.start will not be included in the saved file. The default value for this argument is "1"; we recommend not changing this unless file size is a significant issue.
slice.stop	For multislice data files, a range of slices must be specified. Slice numbers grater than slice.stop will not be included in the RData file to be analyzed by DAT.
