Merci de votre aide

Bonjour,

A priori le champ metricdata n'existe pas dans la structure handles lorsque tu essayes de le récupérer.

Une solution pourrait-être d'initialiser la structure dans l'OpeningFcn (créer tous les champs avec des valeurs par défaut).

Sinon tu peux vérifier l'existence des champs avec la fonction ISFIELD
