Dear Yamashita, This is a great resource and I am very thankful that you made it available to all of us.
One minor issue: It looks like "remove all dead stones" doesn't always work. An example is 206_19_0114_2k_r16_add300_7/20170312_0018_05484.sgf , where a black stone at P18 is left on the board for no apparent reason. Do you know why white passed on move 420? I haven't studied how often this happens, but it means I will need to do some additional processing before I can use the final ownership map as something that a DCNN would predict. Thanks! Álvaro.
