+| `TRKBase.layoutMLOT` | `kCylindrical`, `kSegmented` (default)     | `kSegmented` produced a Turbo layout for ML and a Staggered layout for OT                                                                 |
 | `TRKBase.layoutSRV` | `kPeacockv1` (default), `kLOISymm` | `kLOISymm` produces radially symmetric service volumes, as used in the LoI |
 
 For example, a geometry with fully cylindrical tracker barrel (for all layers in VD, ML and OT) can be obtained by
 ```bash
 o2-sim-serial-run5 -n 1 -g pythia8hi -m A3IP TRK FT3 TF3 \
-  --configKeyValues "TRKBase.layoutVD=kIRISFullCyl;TRKBase.layoutML=kCylinder;TRKBase.layoutOL=kCylinder"
+  --configKeyValues "TRKBase.layoutVD=kIRISFullCyl;TRKBase.layoutMLOT=kCylindrical"
 ```
