[Chimera-users] Some UCSF Chimera marker (.cmm) bonds written as pseudobonds in pdb

Dear RBVI, I have UCSF Chimera marker set made by Volume Traver, and I used "Write PDB" in the model panel to transfer the .cmm file as .pdb file. However, when I opened newly created .pdb file, only about 4.3% of bonds were being shown as bonds, and the rest were being shown as pseudobonds. Is there any reason for this phenomenon? Best, Junha.
