I have a gene-count matrices from chicken and mouse samples processed via cellranger. I am attempting to analyze them using Seurat's multi-dataset vignette. I need to convert the gene names from one of the samples to their orthologous names in the other sample. There are plenty of examples mapping from human to mouse, but I'm not sure how to do it for mouse and chicken. I was thinking I could go from mouse to human and then from human to chicken, but is there a more straightforward way?
