 After evaluation of your dataset using alignments and classifications you may want to exclude particles contributing to less well defined classes in your dataset. To do so, you may first use the [[eyes:​interactive:​extract|interactive Extract]] logic to select poorly defined class sums, or those showing artefacts like hole borders, ethane blobs, etc. and then the [[eyes:​logics:​extractbymember|ExtractByMember]] logic to exclude particles from your dataset that contribute to these bad class sums. After evaluation of your dataset using alignments and classifications you may want to exclude particles contributing to less well defined classes in your dataset.
