This page contains the computer codes for analyzing the fluorescence images obtained from two-photon optical imaging studies conducted in the following journal paper in Current Biology. Title: The habenula-interpeduncular nucleus-median raphe pathway regulates the outcome of social dominance conflicts in mice Authors: Miho Matsumata, Kenzo Hirao, Takuma Kobayashi, Takehisa Handa, Yijun Zhou, Taku Sugiyama, Hisaya Kakinuma, Tanvir Islam, Yuki Kobayashi, Arthur J. Huang, Deepa Kamath Kasaragod, Thomas J. McHugh, and Hitoshi Okamoto The computer codes uploaded here were used to detect cell bodies and corresponding time signals from two-photon calcium imaging movies, extract groupwise list of cells and conduct statistical comparison among groups.
