Dear All,

By chimera I have saved a PDB file, but at the end of the saved PDB there are following sentences which I do not understand:

CONECT 3 2 4 17

CONECT14560145591456114574

CONECT29117291162911829131

Will you please explain it to me the meaning of "CONECT 3 2 4 17" and the other 2 sentences? And why there is no space in "CONECT14560145591456114574"?

Smith
