One anchored simulation run corresponds to one specific `CYCLE` of one `SPLITID` and contains a given number of timeframes as indicated by the big blue box on the bottom right.
A full `RUN` is covered when all `CYCLES` have been produced for all `SPLITIDS`.

The following is an example to run one anchored simulation, in this case `apass2` anchored to `RUN` 544121. Note that if one wants to consistently fill a run, the number of timeframes must be the same for all `CYCLES` and `SPLITIDS`.

```bash
# example anchoring

There are two examples for anchored simulations:

* [PbPb](https://github.com/AliceO2Group/O2DPG/blob/master/MC/run/ANCHOR/tests/test_anchor_2023_apass2_PbPb.sh),
* [pp](https://github.com/AliceO2Group/O2DPG/blob/master/MC/run/ANCHOR/tests/test_anchor_2023_apass2_pp.sh).
