       This will cause input files with the same basename to be grouped together!
 
+## Combining with other options
+
+Once DATs have been generated from input files, they are processed the same as any other DAT file. That means:
+
+- **Parent/clone information may be [inferred](overview.md#parentclone-inference) from game names.**
+
+    If your input files are in some kind of standard naming convention (e.g. [No-Intro](https://wiki.no-intro.org/index.php?title=Naming_Convention), [Redump](https://datomatic.no-intro.org/stuff/The%20Official%20No-Intro%20Convention%20(20071030).pdf), or [TOSEC](https://www.tosecdev.org/tosec-naming-convention)), then parent/clone information can be inferred for [1G1R preferences](../roms/filtering-preferences.md).
+
+    Parent/clone information also allows for [merging & splitting](../usage/arcade.md) of ROM sets.
+
+- **[ROM filter options](../roms/filtering-preferences.md) can be applied.**

 ## Alternative tools
 
 It is unlikely that any ROM tool, including `igir`, will ever meet every person's exact DAT creation needs.
