Description
This function transforms a 4D image array into a 2D image matrix by unrolling space.
This is usefull to perform a subsequent ICA.
Usage
fourDto2D(volume.4d, tm)
Arguments
volume.4d
a 4D array to be transformed
tm
number of time dimensions
Value
a matrix of size tm x vm which contains the tm images
See Also
threeDto4D
twoDto4D
Examples
volume.4d <- array(rnorm(96), dim = c(2, 4, 4, 3)) # a fake 4D image array
