<br> symbol after peptide sequence

Hi there
I have got a problem that
symbol exists at the end of peptide sequence like this (CRLLKPLLC**
**) . I try to select the active residue of peptide as i want to make a protein - peptide docking . I don’t know what does this mean ? Is it a problem in peptide pdb file ? But I’ve checked it for errors and I didn’t find any error.

What do you mean by

Where do you see this ?

<br> statement is a famous HTML tag for line break ( similar to \n ).
You can safely remove it, as probably not part of the peptide sequence.

Do you have multiple TER in your input PDB file ?
