Hi Shane, With PyMOL v1.5 and later, and a reasonable machine you should be able to use large systems (>250,000, and upward of 1,000,000+ atoms) without much of a problem. Using the following simple test script:
fetch 2xpj, type=pdb1, async=0 split_states 2xpj delete 2xpj orient For these 240,000 atoms on a Dell T5500 with a very nice video card, I get: * 30 FPS as lines * 28 FPS using cartoons * 30 FPS a ribbons * 30 FPS as surface For these 240,000 atoms on a (1 year old) MacBookPro (with ATI Radeon HD 6770) I get * 60 FPS as lines * 33 FPS as cartoon * 36 FPS as ribbon * 27 FPS as surface 30--60 FPS is surely in the realm of "interactive". Earlier versions of PyMOL would have a tough time with these data. (Plus the new versions of PyMOL have nicer rendering in real time.) Next, you wrote: > Is a 12-core mac like this overkill? > http://store.apple.com/us_smb_78313/configure/MD771LL/A With Moore's Law still in effect, nothing is overkill. However, consider value for money: the recent announcements from Apple centered around the MacBookPro -- not the MacPro. It should be clear that those who financially support PyMOL are responsible for this level progress. The diff from v1.4 to v1.5 was in the range of 50,000+ lines -- and we couldn't have done that work without our supporters. So, a special thanks goes out to them!
