cal_img

Rescales image cal_max and cal_min slots to be the max and min,
respectively, of an object of class nifti, with <code>na.rm=TRUE</code>. This is so that
when images are rendered/written, the values correspond to those
in the array (stored in .Data slot) are plotted on correct grayscale and no error is
given by <code>writeNIfTI</code>.

Wrapper functions that interface with FSL
    (http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/), a powerful and commonly-used
    neuroimaging software, using system commands. The goal is to be able to
    interface with FSL completely in R, where you pass R nifti objects and the
    function executes an FSL command and returns an R nifti object if desired.
