[phenixbb] elbow question

Dear colleagues, am I alone in thinking that in my example phenix.elbow gave me more than what I was asking for, specifically atom H11 attached to sulfur? Is it added by elbow, or does it originate from the "--chem=tpp" input? Best regards, Wolfram Tempel command line: phenix.elbow --chem=tpp --mogul phenix version: 1.7.1-743
