MRIaggr-selectParameter: Extract parameters

In bozenne/MRIaggr: Management, Display, and Processing of Medical Imaging Data

Description

Extract parameters from a Carto3D or from a MRIaggr object.

Usage

## S4 method for signature 'Carto3D'
selectParameter(object)

## S4 method for signature 'MRIaggr'
selectParameter(object, type = "contrast", mask = TRUE)

Arguments

object	an object of class MRIaggr. REQUIRED.
type	the type of parameter to select. character. See the details section.
mask	should the mask be considered as an available contrast parameter ? logical.

Details

ARGUMENTS:
Possible values for type are:

• "clinic" : return the name of the clinical parameters.

• "contrast" : return the name of the contrast parameters.

• "ls_descStats" : return the name of the elements in @ls_descStats.

See Also

allocContrast<- to allocate new parameters.

Examples

#### 1- Carto3D method ####
## load NIFTI files and convert them to Carto3D
path.Pat1 <- system.file("nifti", package = "MRIaggr")
nifti.Pat1_TTP_t0 <- readMRI(file.path(path.Pat1, "TTP_t0"), format = "nifti")
Carto3D.Pat1_TTP_t0 <- constCarto3D(nifti.Pat1_TTP_t0, identifier = "Pat1", param = "TTP_t0")

## selection
selectParameter(Carto3D.Pat1_TTP_t0)

#### 2- MRIaggr method ####
## load a MRIaggr object
data("MRIaggr.Pat1_red", package="MRIaggr")

## extract all imaging parameters
res <- selectParameter(MRIaggr.Pat1_red)

## extract the names of the parameters in the slot @ls_descStats
res <- selectParameter(MRIaggr.Pat1_red, type = "ls_descStats")
