Hi, Dr Stark
I found when I pool three group in a experiment, like groupA, B, C. The Conc_A in dba.report is slightly different between GroupB_VS_GroupA and GroupC_VS_Group_A.
Just my own data
library(tidyverse) a <- read.csv("result/Diff_Peak_Anno/H3K27ac/SIM3d_H3K27ac_VS_CIM7d_H3K27ac.csv") %>% select(feature_id, Conc_CIM7d_H3K27ac) b <- read.csv("result/Diff_Peak_Anno/H3K27ac/SIM8d_H3K27ac_VS_CIM7d_H3K27ac.csv") %>% select(feature_id, Conc_CIM7d_H3K27ac) # sometimes, the diff will be bigger > inner_join(a, b, by = "feature_id") %>% + mutate(diff = Conc_CIM7d_H3K27ac.x - Conc_CIM7d_H3K27ac.y) %>% + pull(diff) %>% + table() . 0 0.00999999999999979 0.01 3971 13053 76 0.0100000000000002 0.0100000000000007 0.0100000000000016 75 1083 1297
by the way, I find it is hard to open the link posted in the DiffBind manual.
