Those files stretch the definitions of "PDB" format -- the residue
names are 5 characters, the atom names are in the wrong columns, and
all the atoms in one file are named "H" and all the atoms in the other
file are named "O"!
However, I realize many programs write nonstandard "PDB" formats to
show various things and it is useful to view them.
The initial default display can be adjusted in the Preferences
(Favorites... Preferences), category "New Molecules." Change "smart
initial display" to "false" and click Save if you want that to apply
to later uses of Chimera.
Alternatively (instead of changing New Molecule preferences) you could
create an alias to show nucleic acids as all atoms, for example with
alias ^plain nuc side atom; ~ribbon nucleic acid
and in recent Chimera (v 1.5, so daily builds) that would be saved in
your preferences file. You could execute that alias with the command
"plain", for example:
or by choosing it from the top-level Aliases menu. That menu appears
when "^" (start-of-line) aliases are defined in recent Chimera 1.5
I hope this helps,
