View source: R/DAT.checkData.R

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.

1 2	DAT.checkData(file.name, vector.times, map.CC, mask.ROI, vector.AIF, slice.start=1, slice.stop="not.specified")

`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`.
