If you ask the question, then also ask same for HCMD2 and DDDT2 that are also quorum 2. It's either having a dataset "by close proximity" i.e. no 100% confirmation needed, where large groups of results lead to conclusions and pointers to compounds and energies of how proteins fold and compounds dock, versus creating a worldwide accessible database of "absolute verified" information, in the ~135 million for HCC now [300 million at quorum 2+error checks], that scientists can use to slice and dice and apply analysis to, down to the single crystal processed.

Best example of ZR is Rosetta [HPF2], which looks for folding patterns [80000 results I think grouped, was 30000 or so], HCMD2 looks for issues down to the single amino-acid combination. What's the value of the dataset if you can't be sure the annotation is 100% absolute accurate... when it's demonstrated that 2 computers can have slightly different results coming out [yes really, the volunteer computers is not a known set of homogeneously operating calculators, all processing photons in the same quantum mechanical way], which is why there are tolerances included as specified by the respective project scientists when we deal with the ZR projects, and usually only after a huge dataset has already been build to give statistical confidence levels of a very high order]. A random pick [10%-20% or so] still leaves doubts for the objectives the HCMD2/DDDT2/HCC scientists have set.

HCC has run now come November 5 years... the scientists could have had it done in 3, if they'd considered single copy, and rest assured that question will have been asked a few times.

BTW, in past much better answers were given on the forums than mine of how I understand this, and would not be surprised if Help has an outline conceptual explanation. I've not looked.

OK, I think I got it now. What I should have probably figured out by myself is that "slightly different results" from different computers statement. Even though that kind of makes me question the whole system and swing directly in the opposite direction and say "are 2 computers really enough then?".

As you said, this question must've come up at least once before, but I will grant you that I am lazy and still haven't figured out how to use the search function on this forum as every time I have tried it, it seems to blurt out every single post ever posted here, regardless of what I have typed in or how many filters I applied. But that's a different topic.

Anyway, thanks for your replies. Cheers!

Thanks again for the tips, SekeRob! I will try it next time I need to find something, especially before opening a new thread.

Cheers!
