Re: CCL:insightII/discover vs CHARMM

Yao-Ying:
 I am not a CHARMM user but do use a similar program - Amber.  I have
 also used Insight.  There are pros/cons to either and it will depend on
 your circumstances.  However, some pros/cons that come to mind are:
 Insight costs a lot more than Charmm if you are at an academic
 institution (ca $20,000 for Insight, less than $1000 for Charmm, last I
 checked, $600).
 Insight only runs in a serial environment, charm, I believe, runs in
 either a serial or parallel mode.
 Insight will offer tech service, charmm doesn't directly.  However, I
 have not been impressed with Insight's tech service and listserves for
 charmm are free and probably more helpful.
 Insight has excellent graphics.
 Both will solve protein/dna problems.  Which is better for either
 problem is debatable.
 Here's a third option to consider.  Get NAMD/VMD.  These programs will
 do anything that Insight/CHARMM/Amber will do but NAMD/VMD are free.

 Hi,
 Can someone tell me the pro's and con's of insightII/discover vs CHARMM?
 I have used insightII/discover, but most people here seem to use CHARMM.
 Wonder if you guys can explain for me the difference, in terms of the
 pro's and con's? And if any reasons I should switch to CHARMM?
 URL's discussing these are appreciated too.
 Thanks,
 Yao
