Dear Authors, While browsing through the Pangenome files, we noticed a strange pattern: For some contigs, we see genes that have the same start-end position but different Uniref90 IDs annotated (in a single contig). Here, we attach some examples: From `Mycolicibacterium_obuense`. ```auto UniRef90_A0A0M2WDJ6 WN67_31095 GCA_000974925 LAUZ02000002.1 72597 93944 ... UniRef90_A0A0J6VR76 WN67_31095 GCA_000974925 LAUZ02000002.1 72597 93944 ``` From Lysobacter\_capsici ```auto UniRef90_A0A0Q8IVI6 dltA GCA_001442785 CP011130.1 2970103 2990550 ...

Best, Eric Cho
