Abstract: Phages are among the most abundant and diverse biological entities on earth. Identification from sequence data is a crucial first step to understand their impact on the environment. A variety of bacteriophage identification tools have been developed over the years. They differ in algorithmic approach, results and ease of use. We, therefore, developed 'What the Phage' (WtP), an easy-to-use and parallel multitool approach for phage identification combined with an annotation and classification downstream strategy, thus, supporting the user's decision-making process when the phage identification tools are not in agreement to each other. WtP is reproducible and scales to thousands of datasets through the use of a workflow manager (Nextflow).
