**The steps of structure solution by DM**

Using the command %continue, the program runs in default conditions carrying out the commands

%extraction

%normal

%invar

%phase

%fourier

%menu

%end

and each command corresponds to a step in the structure solution with Direct Methods. All the following steps are described.

1)Extraction of the integrated intensities (%extraction command)

2)Normalization of the integrated intensities (%normal command)

3)Triplet invariants estimate (%invariants command)

4)Phasing by the tangent formula (%phase command)

5)Fourier map calculation and crystal structure optimization (%fourier command)
