Dear Smith, The CONECT lines are part of standard PDB format. They describe bonds that are not already implied by the residues/chains in the file. They have a standard fixed format, where each piece of information must be in certain columns, so if the numbers are long enough, there won’t be spaces between them. See the description of PDB format at the wwPDB website for the details of CONECT (and other parts of a PDB file): <http://www.wwpdb.org/documentation/file-format> <http://www.wwpdb.org/documentation/file-format-content/format33/sect10.html#CONECT> Best, Elaine ---------- Elaine C.

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"?
