1. Min:sec between entering the PDB code and the final disappearance of "BUSY" after the tabs at
the top left had appeared.
Times measured after JSmol & FirstGlance were already in the browser cache
(1d66 had previously been displayed in the same browser session).
2. Edge and Internet Explorer operate JSmol unacceptably slowly. See
browsers.
Italics: First load (times measured after the browser cache had been cleared). Clocked on a mid-2014 MacBook Pro (Mojave, 2.2 GHz i7, 16 GB 1600 MHz DDR3). Internet Explorer and Edge clocked in a Windows 10 virtual machine (VMWare, same hardware). 3. There are no hydrogen atoms in this model. 4. Atom count includes hydrogens. Non-hydrogen atom count for 7ahl=17K. 5. Mostly RNA: 36K atoms RNA, 24K atoms protein. 6. 99,999 atoms are the maximum possible in the PDB format. FirstGlance does not yet handle mmCIF.
Greater than 99% of entries in the PDB are available in the PDB format.
7. Percentages of entries in the PDB determined January 23, 2019 by MW search,
when there were a total of 148K entries in the PDB.

Presenting Views from FirstGlance, which can be
accessed from a link at the bottom of the lower left panel in FirstGlance.
The initial view now marks regions with missing residues
with an "empty basket" (see image at right). The empty baskets
