The [NAME] method uses the current model names, so if the model name is the same as the first part of the original filename, it will work the way you want. If the model name is not what you want in the output filename, you can change it (the model name) using the "rename" command: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/rename.html> No you cannot put multiple names in the square brackets, only NAME or ID as mentioned in the "save" docs to insert the current model names or ID numbers. <https://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#pdb> I hope this helps, Elaine ----- Elaine C.

Dear Elaine, Eric and Oliver,
Elaine, yes, indeed, the email list I used was wrong. Thank you for mentioning that.
Indeed - I managed to open the large number of files using the command you mentioned open 2gbp 2fw0 1plx 1plz And after I thought there is a command like save 2gbp.pdb #1 2fw0.pdb #2 .....exists. But it didn't work.
Great that's the following command exists - so I was not far away )). save test/[NAME].pdb models #2-4
But in the case of this saving command will models #2-4 keep their original PDB name? Or shall I specify it separately? save test/[2fw0 1plx 1plz].pdb models #2-4
If not, is there a way to save the multiple PDB's with their original name?
Kind regards Dmitry

Thanks Eric! Sorry I forgot about this convenient option.
I just tried the following to see if it saves multiple files, and it does:
open 2gbp 2fw0 1plx 1plz save test/[NAME].pdb models #2-4
...namely, I get files in ~/Desktop/test/ named 1plx.pdb 1plz.pdb 2fw0.pdb
One weirdness, however, is that 1plx is an NMR model (ensemble of 80 structures, opened as 80 submodels) and this approach only saves one structure (the last one) in the PDB file. We should investigate that. I don't have that problem if I save 1plx without the [NAME] mechanism, however.

Should probably also mention that this special feature is only available for PDB and mmCIF files.

If by "multiple" you mean a huge number that is not practical to put in a single command, that is a different matter. Also, a single "save" command only saves one file and it does not have option to automatically figure out filename from model name.
This is not completely correct, in that if the “file name” you save contains the literal string “[NAME]” in it, then a file will be saved for each model (that was specified in the save command) and each file name will have the [NAME] part replaced with the model name.
