Description Usage Arguments Details Value See Also Examples

Compute the four first order statistics of the contrast parameters by cerebral structure.

1 2	## S4 method for signature 'MRIaggr' calcDistTissues(object, param, param.membership, num = NULL, hemisphere = "both")

`object`	an object of class `MRIaggr`. REQUIRED.
`param`	the contrast parameters to consider. character vector. REQUIRED.
`param.membership`	the parameters indicating the probabilistic membership of each observations to each cerebral structure. character vector.
`num`	the slices to use. numeric vector or `NULL`.
`hemisphere`	the hemisphere to use. character.

ARGUMENTS :
Information about the num argument can be found in the details section of initNum.

Information about the hemisphere argument can be found in the details section of selectContrast.

An data.frame containing in row the various cerebral structures and in columns the various moments for each contrast parameter.

calcTissueType to compute a probabilistic classification of the brain observations in WM/GM/CSF.

## load a MRIaggr object
data("MRIaggr.Pat1_red", package = "MRIaggr")
	   
## compute the distribution of DWI and T2 FLAIR for the CSF, WM, GM and lesion observations
res <- calcDistTissues(MRIaggr.Pat1_red, param = c("DWI_t0","T2_FLAIR_t2"),
                        param.membership = c("CSF","WM","GM","MASK_DWI_t0")
)
