WitrynaBut if you are expecting relatively small changes in expression (2-fold difference), a log(2)-transformed value of '1' looks better (bigger) than a log(10)-transformed value of 0.3. Witryna이를 해결하는 방법 중 하나는 FC를 그대로 쓰지 않고 log 2 (FC)로 전환하는 것이다. 단 FC = 0인 것은 적절히 제거를 하든지 전처리를 해야 한다. FC에 밑이 2인 log를 씌우면 대칭적인 값을 얻음과 동시에 음수 (-)가 나올 수도 있다. 설명하자면 다음과 같은 것이다. log 2 (FC) = 1, 2, 3이면 control에 비하여 treatment가 2배, 4배 (2 2 ), 8배 ( 2 ). log 2 (FC) = 0이면 …
