# Mapping Metrics

Columns in the MappingSummary.csv.gz

YAP gathers many mapping metrics from each step of the pipeline. 

To quickly evaluate the cell and library quality, you may start with a few key mapping metrics and recommended cutoffs:

{% content-ref url="/pages/-MHxBvOPootAsfzAggC8" %}
[Key Mapping Metrics](/mc/mapping-metrics/key-mapping-metrics.md)
{% endcontent-ref %}

And I also provided the annotation of all mapping matrics in the `MappingSummary.csv.gz` table. 

{% content-ref url="/pages/-MHUWTYFOMCs5-Jfth8z" %}
[All Mapping Metrics](/mc/mapping-metrics/all-mapping-metrics.md)
{% endcontent-ref %}
