makeVolume: makeVolume

In neuroim: Data Structures and Handling for Neuroimaging Data

Description

Construct a BrainVolume instance, using default (dense) implementation

Usage

makeVolume(data = NULL, refvol, source = NULL, label = "",
  indices = NULL)

Arguments

data	an optional one- or three-dimensional vector or array
refvol	an instance of class BrainVolume containing the reference space for the new volume.
source	an optional instance of class BrainSource
label	an optional character string
indices	an optional 1d vector of indices in to the 3d space

Value

DenseBrainVolume instance

Examples

bspace <- BrainSpace(c(64,64,64), spacing=c(1,1,1))
dat <- array(rnorm(64*64*64), c(64,64,64))
bvol <- BrainVolume(dat,bspace, label="test")
bvol2 <- makeVolume(dat, bvol)
all.equal(as.array(bvol),as.array(bvol2))
data <- 1:10
indices = seq(1,1000, length.out=10)
bvol3 <- makeVolume(data,bvol,indices=indices)
sum(bvol3) == sum(data)
