SFTOOLS will do the calculations. A phase increase of 2piR.S or 2pi(rx h + ry k + rz l), or in SFTOOLS syntax (R=[0.0,0.25,0.5]):
calc p col tmp1 = 360 0.0 * H * calc p col tmp2 = 360 0.25 * K * calc p col tmp3 = 360 0.5 * L * calc p col PHINEW = col PHIOLD col tmp1 + col tmp2 + col tmp3 + Programs PHASECHANGE and CPHASEMATCH are of related functionality.
