If you mean amber coordinate files, the filetype you are looking for is called “rst7“.


You can always turn on TCL command logging to get the commands for operations you know how to do using the GUI. (VMD Main->File->Log TCL Commands to console)


What you basically need:


set files “file1.pdb file2.pdb file3.pdb”

foreach f $files {

               set mid [mol new $f]

               set sel [atomselect $mid all]

               $sel writerst7 $file.rst7

               $sel delete

               mol delete $mid



Good luck
