Just delete the residues you don't want.  E.g. if  the residues are numbered 1-1000 and you don't want 501-1000, then command:<br>
<br>
delete :501-1000.a<br>
<br>
... of course, you can use any command-line atom specification, e.g. selecting that part and then<br>
<br>
delete sel<br>

<br>
If you wanted it as a file, then just save a PDB file after you do the deletion.  E.g. menu File... Save PDB, or command "write":<br>

I hope this helps,<br>
