Dear all,

> give me information for software chemistry freedownload

At http://www.cheminformatics.org

I compiled a directory of free cheminformatics / computational
chemistry tools I compiled over the last year or so ("free" in this
context means that the license should be of no cost to academic
researchers) and it now contains about 630 links both to software as
well as databases.

The directory is structured (although I should clean up a bit I
suppose ...) so you should be able to locate suitable programs fairly
quickly.

Hope that helps,
Andreas
