CCL: Free Conformational Analysis Software

 Sent to CCL by: Roger Kevin Robinson [r.robinson()]
I was wondering if any one knew if there is any free conformation analysis software either for Linux or Windows. Ive been used to using Cerius2 (drieding) but this is no longer available to me.
I tried Dynamol but it doesnt seem to be able to choose the lowest energy confermer. Although it can generate all confermers.
 Any advice would be appreciated.
