Freeware for molecular modelling - On PC? (Jan/30/2006 )


is there any nice freeware for molecular modelling?
i'm using Insight 2000 but i'd like to work on my PC (if possible)...

thanks wink.gif



Chimera is pretty neat... I've been playing around with the Linux version for awhile now.

They have a Win32 version as well.





thank you a lot!
these softwares seem cool wink.gif
but can we build molecules with Chimera?



something that was suggested today by someone in the lab is:

Looks good. I haven't used it yet.

I have the links here:


since i was searching for a modeling tool (not a viewer...), BALLView was the best freeware i have tested
for information see the paper:

many thanks to people who give us nice tools freely wink.gif
