 - **Description**: Whether to output the density of states (DOS). For more information, refer to the [dos.md](../elec_properties/dos.md).
   - 0: no output
   - 1: output the density of states (DOS) 
-    - nspin=1 or 4: `dos1.txt` and `dos1_smear.txt` with the latter one with smearing effect 
-    - nspin=2: `dos1.txt` and `dos2.txt` for two spin channles. In addition, `dos1_smear.txt` and `dos2_smear.txt` for data with the smearing effect.
+    - nspin=1 or 4: `doss1g{geom}_{basis}.txt`, where geom is the geometry index when cell changes or ions move while basis is either `pw` or `nao`.
+    - nspin=2: `doss1g{geom}_{basis}.txt` and `doss2g{geom}_{basis}.txt` for two spin channles.
   - 2: (LCAO) output the density of states (DOS) and the projected density of states (PDOS)
   - 3: output the Fermi surface file (fermi.bxsf) in BXSF format that can be visualized by XCrySDen
