Dear Grace,
There are probably some free descriptor generating software modules out
there for Academia. EduSoft (http://www.edusoft-lc.com/molconn/) offers
one of the most comprehensive softwares for the original Kier-Hall descriptors.
This original program has been significantly updated and the number of
descriptors expanded to several hundred. These descriptors are based on
molecular connectivity and chemical graph theory. They are 1-D and 2-D
values. There are not many programs that I am aware of that offer large
3-D descriptor sets. EduSoft also offers a simple "hydropathy"
(evaluating
hydrophobic and hydrophilic components) program, HintLogP
(http://www.edusoft-lc.com/hint/) which will provide several
2-D and a few
3-D descriptors. Of course 3-D descriptors REQUIRE and absolute 3-D
structure (not a guess from SMILES/Depict programs).
These programs are not FREE, but we do offer an 80% discount to Academics.
I believe that Mesa Analytics (http://www.mesaac.com/) may be developing
some software for the classroom called "Virtual Classroom" that may be
free for Academics. This software also includes the Molconn-Z descriptors.

question previously. Now I am wondering if anyone knows there is any free
software which can help me to generate the regular common 1D, 2D and 3D
descriptors so that I can perform QSAR analysis efficiently? Thanks,
