The dataset is first categorized into two folders (Bmal and Per2) based on the promoter reporter. The data is further separated by experiment date/treatment time of day (standard timing versus delayed timing, indicated as "standard" and "delayed," respectively). For the data labeled "standard" the cells were treated with small molecules immediately after synchronization. For data labeled "delayed" the cells were treated with molecules 12 h after synchronization. Each excel file will have the date the experiment started followed by the promoter gene, treatment time, and treatment type (MT = melatonin, NT = not treated, DMSO = vehicle, UCSF7447 = melatonin receptor-targeting molecule).
