Thanks Michael, this worked:

--------------------
      run("Raw...", "image=8-bit width=100 height=1 offset=0 number=1");
      width = getPixel(1,0)*256 + getPixel(0,0);
      height = getPixel(3,0)*256 + getPixel(2,0);
      slices = getPixel(5,0)*256 +getPixel(4,0);
      path = "'"+getDirectory("image")+getTitle+"'";
      run("Close");
      run("Raw...", "open="+path+" image=8-bit width="+width+"
height="+height+" offset=512 number="+slices);
-----------------------
