fslmask(
file,
mask,
outfile = NULL,
retimg = TRUE,
reorient = FALSE,
intern = FALSE,
opts = "",
verbose = TRUE,
...
)

additional arguments passed to |

Result from system command, depends if intern is TRUE or FALSE.
Functions with underscores have different defaults and will return an output filename, so to be used for piping
if (have.fsl()){
system.time({
x = array(rnorm(1e5), dim = c(100, 100, 10))
img = nifti(x, dim= c(100, 100, 10),
datatype = convert.datatype()$FLOAT32, cal.min = min(x),
cal.max = max(x), pixdim = rep(1, 4))
mask = img > .5
masked = fslmask(img, mask = mask, retimg=TRUE)
})
