#Bioinformatics life:
When working with #data from multiple #species, it is important to keep them separate. This is a particularly a problem with #human and #mouse data: we're pretty similar, big-picture-wise, with a lot of similarly named #genes that do similar things. So you want to make sure your species labels for each datum are clear and unambiguous.
Note to self: it helps if you label them "mouse" and "human" rather than ... say ... just to choose a random example ... "muman". Because trying to make *that* happen will get your funding yanked rather quickly.
