AFNI program: 3dAttribute

Usage: 3dAttribute [options] aname dset
Prints (to stdout) the value of the attribute 'aname' from
the header of dataset 'dset'.  If the attribute doesn't exist,
prints nothing and sets the exit status to 1.

Options:
  -name = Include attribute name in printout
  -all  = Print all attributes [don't put aname on command line]
          Also implies '-name'.  Attributes print in whatever order
          they are in the .HEAD file, one per line.  You may want
          to do '3dAttribute -all elvis+orig | sort' to get them
          in alphabetical order.
