[Chimera-users] INQUIRY

Hello Please how do I prevent chimera from renumbering my protein residue sequence in cases where I am working with a pdb structure that does not cover all the residues? For example, the attached pdb protein file (5trf.pdb) was downloaded from the pdb database with the first 9 residues missing. The first residue in the pdb structure is the 10th residue and this was numbered accordingly but whenever I upload such structures on Chimera, the numbering of the residues tend to scatter because chimera automatically numbers the first residue in the structure as 1, just as it appeared in the attached mol2 file. Please how do I avoid/correct such Thank you.
