做DESEQ2换了个文件就出错，代码是Error in DESeqDataSet(se, design = design, ignoreRank) :
  some values in assay are not integers，请问各位大佬怎么解决啊？
具体代码如下：
library(DESeq2)
setwd("D:/RDATA")
mycounts<-read.csv("500samplegutotu.csv",header = T)
head(mycounts)
rownames(mycounts)<-mycounts[,1]
mycounts<-mycounts[,-1]
head(mycounts)
condition<-factor(c(rep("case",69),rep("control",422)),levels=c("case","control"))
condition
colData<-data.frame(row.names = colnames(mycounts),condition)
colData
dds<-DESeqDataSetFromMatrix(mycounts,colData,design= ~condition)
