 The Class `dpdata.MultiSystems`  can read data  from a dir which may contains many files of different systems, or from single xyz file which contains different systems.
 
 Use `dpdata.MultiSystems.from_dir` to read from a  directory, `dpdata.MultiSystems` will walk in the directory 
 Recursively  and  find all file with specific file_name. Supports all the file formats that `dpdata.LabeledSystem` supports.
 
-Use  `dpdata.MultiSystems.from_file` to read from single file. Now only support quip/gap/xyz  format file.
+Use  `dpdata.MultiSystems.from_file` to read from single file. Single-file support is available for the `quip/gap/xyz` and `ase/structure` formats.
 
 For example, for `quip/gap xyz` files, single .xyz file may contain many different configurations with different atom numbers and atom type.

+    Use the `ase_fmt` keyword argument to supply the format if
