dpgen : sys_configs does not support glob pattern as expected

[ccchenjj]

When using a glob pattern like "init/sys-0001/0000[0-9]/POSCAR" in sys_configs, dpgen run raises an error :
"RuntimeError: run_tasks for model_devi should not be empty! Please check your files."
However, replacing it with "init/sys-0001/0000*/POSCAR" works as expected.
What happened to this?
dpgen 0.13.1
python 3.11.13

DP-GEN does support Python glob character classes such as [0-9]. The pattern in the question matches a different directory-name length.

0000[0-9] matches exactly five characters: 00000 through 00009. DP-GEN-generated frame directories are commonly six digits, such as 000000, so that pattern matches nothing and later produces “run_tasks ... should not be empty”.

For six-digit directories, use for example:

init/sys-0001/00000[0-9]/POSCAR

for 000000–000009, or:

init/sys-0001/0000[0-9][0-9]/POSCAR

for 000000–000099. The broader 0000* works because * consumes the remaining digits. You can verify the exact expansion before running DP-GEN with Python's glob.glob(...).
