Issue when running the pipeline on santamarta

J'ai un soucis quand je lance la pipeline sur le jeu de données des caraibes.

Le problème arrive à l'étape 6 au moment de l'assignement. Tout le reste semble s'être bien passé, cf les logs et nohup situé dans le dossier suivant:

/media/superdisk/edna/working/santamarta_providencia/snakemake_rapidrun_swarm/

Voici l'erreur que j'obtiens, issue du log:

A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead

See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
