I thank you very much for the help!
Indeed "Change Chain IDs" has recognized correctly each of the
monomers and proposed an assignment of the unique ID for it ( I
checked initial pdb - actually there were no chain assigments within
One question- is it possible to perform the same assignment
automatically using batch-chimera, providing as an input some script
file and the initial pdb ? E.g. to assign unique chain name
automatically for each protein entities w/o identified chains.

Since they all have the same ID to start with, you would have to use the workaround given in the page for “Handling multiple chains with the same ID”
