Hi, pymol users.
I'm a pymol newbie .I have serval question.
I have a pdb file which include the information about box size, like
TITLE     God Rules Over Mankind, Animals, Cosmos and Such
CRYST1   39.000   39.000   56.140  90.00  90.00  90.00 P 1           1
MODEL        1
HETATM    1  C   UNK     1      25.851  19.500   0.710  1.00  0.00

I run pymol, and load it, then delete some molecules and save it. Now the information about box size is losing.

2. Is there any way to get  the information about bonds, angles and dihedrals ?
   I found the following command can display the bonds information, but can't be assigned to a variable.
      >print atoms.list()
3. Is there any way to learn these python api commands of pymol ?

Thank you!
