I recently wrote about my workflow for Analyzing Microbial Growth with R. Perhaps the most important part of that process is the plate map, which describes the different experimental variables and where they occur. In the example case, the plate map described which strain was growing and in which environment for each of the wells used in a 96-well microtiter plate. Until recently, I’ve always created two plate maps. The first one is hand-drawn using pens and markers and sat on the bench with me when I started an experiment. By marking the wells with different colors, line types, and whatever other hieroglyphics I decide on, I can keep track of where everything is and how to inoculate the wells.
