I dare say indefinitely. Your crystal life expectancy drops rapidly though with somebody not remembering to fill up the dewar. Transferring crystals to pucks etc. is another problem. I had some crystals which I could not remember what they were (label broke off the cane) and we simply reshoot

in theory I would say decades/eons. in practice it probably depends on how much water/ice your liquid nitrogen contains, multiple refillings of the liquid nitrogen might slowly deposit tiny ice crystals on the crystals and slowly make diffraction worse... Mark J van Raaij Lab 20B Dpto de

Theoretically? Millions to billions of years. Practically? They will last until the first time you forget to fill the dewar. Or until the Sun explodes and in the rush to leave Earth your descendants forget to pack it. Whichever comes first. Seriously, as long as the crystals have

Tim, naturally, the issue is specific to a particular pdb file (it would be indeed strange if the conversion tool from a major software package would fail in general sense). Ed. On Wed, 2013-05-22 at 08:12 +0200, Tim Gruene wrote: Hi Ed, # pdbvconv -p udo.pdb -o udov.pdb # pdbvconv -p

Dear Tim, I am sorry that you feel offended. It is rather unfortunate that you got an impression from my secondary comment that I am asking for help with pdbvconv when I wasn't. It is also rather unfortunate that I have figured out what the problem was myself and therefore did not have an
