This has some basic datasets for bacteriophages that use alternative genetic codes, and their close standard code relatives. I have included the following: - Genomes for all alternatively coded phages and their relatives - Predicted proteins all alternatively coded phages and their relatives - A sheet with some basic information about these phages - Terminase treefile (Figure 2A) - Genomes for crAss-like phages used in the alternative code bias analysis (Figure 4) - Genomes for Agate phages used in the alternative code bias analysis (Figure 4) as well as the ANI analysis (Figure 3A) - Untrimmed lysogenic contigs for prophages (Like those shown in Figure 5)
