[chimerax-users] PDB upload TER card error

Dear all, I saved my protein coordinates in ChimeraX as pdb (it has multiple chains), however, when I was doing upload on the PDB, it shows this error, I am using ChimeraX 1.5rc202211091945 on Linux ubuntu 22.04 LTS. Coordinates issues: ERROR: There is no TER card at the end of polymer chain 'X'. All polymer chains should have a TER card at the end of each chain. Please add TER card and restart again. Many thanks! Hong
