Please, follow the next steps in order to tag and filter out artifacts from the variant table.
1. Tag a variant as a "Common artefact"
First of all you need to identify all variants that are potential artifacts. To do this you can:
- Add a custom variant classification: click on the
icon and classify the variant as "Common artefact":
- If you have a pre-defined list of common artefacts, you can send us your list and we will label these variants as "Common artefact". Please, find more information here.
Custom classifications and comments are associated to the variant. You only need to classify the variant once and this classification will be kept and shown in case the same variant is found in any other analysis of your VarSome Clinical account.
2. Filter out "Common artefacts"
Click on the 
icon above the variant table to select which variants would you like to show:
Click on show "All except common artefacts". This option will exclude the common artefacts from the variant table.
