Hi Tom,
Thanks for your reply! If I just want to do docking, it is ok, is that right? Or if I want to do MD, how should I add those missing residues? By the way, I follow your suggestion to insert TER between those residues, there are still the same warnings when loaded in xleap. What's the matter? Thanks!
Qinghua

I only looked briefly but this does not look like a complete protein.
Many residues are missing, which leaves many regions unconnected.
Please be sure this is OK for what you want to do (e.g. for MD, the
resulting simulation may be quite different from how the receptor acts
in reality). You may wish to use a complete protein without gaps.
Leap joins together residues that are adjacent in the PDB file, even
if the bond length would be unrealistic. You can keep it from doing
this by inserting TER records in the PDB file between the residues
that need to be separated.
