Hi Boaz,
	The most reliable way to match the pocket atoms listed in the .poc  
file to the PDB is by serial number (due to the vagaries of how CASTp  
formats the .poc file).  Your input PDB (and therefore output PDB) has  
duplicate serial numbers for corresponding atoms in the two chains.   
If you open your input PDB in Chimera and write out a new PDB, the new  
one will have unique serial numbers.  You can use that with the CASTp  
server and get results that Chimera can handle.  Sorry for the hassle.
