Created two activity-files:
A structure was classified as active, if
- at least one strain was >= 0.7 (ac_onestrain.class)
- all strains were >= 0.7 (ac_allstrains.class)

How to create gSpan input file format (perl and ruby required):

1) Remove numbers from ac.smi file to obtain 1 SMILES per row in file ac.no_nr.smi
2) do 'babel -d -ismi ac.no_nr.smi -osdf ac.sdf' to convert to MOL format
3) do 'perl sdf2gsp.pl < ac.sdf > ac.no_nr.gsp' to convert to gSpan input format
4) do 'ruby replace.rb ac.no_nr.gsp ac.smi > ac.f.gsp' to restore correct numbering from .smi file
[ optional: do 'ruby report.rb ac.f.gsp' to report trees without edges ]
5) do 'ruby remove.rb ac.f.gsp > ac.gsp' to remove trees without edges
[ optional: do 'ruby report.rb ac.gsp' to report trees without edges ]
