       rr..llee..ppiixxeell  -  The  _r_._l_e_._p_i_x_e_l  program	contains a set of measures for
       attributes, diversity, texture, juxtaposition, and edge.

   FFllaaggss::
       --bb     Run in background.

       --ee     Output map 'edge' of edges given a '1' in r.le.para/edge file.

       --uu     Output maps 'units_x' with sampling units for each scale x.

       --zz     Output map 'zscores' with standardized scores.


   PPaarraammeetteerrss::
       mmaapp    Raster map to be analyzed.

       ssaamm    Sampling method (choose only 1 method):  w=whole	map,  u=units,
	      m=moving window, r=regions Default: w

       rreegg    Name of regions map, only when sam = r; omit otherwise.

       aatttt    Attribute  measures:  Options:  b1,  b2,	b3, b4 b1 = mean pixel
	      attribute b2 = st. dev.  pixel  attribute  b3  =	minimum  pixel
	      attribute b4 = maximum pixel attribute

       ddiivv    Diversity  measures:  Options: d1, d2, d3, d4 d1 = richness d2 =
	      Shannon d3 = dominance d4 = inverse Simpson

       ttee11    Texture method (choose only 1 method): Options: m1, m2, m3,  m4,
	      m5, m6, m7 m1 = 2N-H m2 = 2N-45 m3 = 2N-V m4 = 2N-135 m5 = 4N-HV
	      m6 = 4N-DIAG m7 = 8N

       ttee22    Texture measures (required if te1 was specified):  Options:  t1,
	      t2,  t3,	t4,  t5  t1 = contagion t2 = ang. sec. mom.  t3 = inv.
	      diff. mom.  t4 = entropy t5 = contrast

       jjuuxx    Juxtaposition  measures  (weight	file  in  r.le.para   needed):
	      Options:	j1, j2 j1 = mean juxtaposition j2 = standard deviation
	      of juxtaposition

       eeddgg    Edge measures: Options: e1, e2 e1 = sum of edges	e2  =  sum  of
	      edges by type (edge file in r.le.para needed)
