Hi

I was performing a differential expression analysis on TCGA RNA-seq data using edgeR. The results of differential expression analysis has NAs under Gene names and Gene symbols. The EntrezID corresponding to it doesnt not give a valid Gene name. What could be wrong? The following command was run for annotating the gene expression data with Entrez ID.

gnsOXP_2 <- select(org.Hs.eg.db, keys=rownames(matrix_OXP_2),columns=c("SYMBOL","GENENAME"), keytype="ENTREZID")

'select()' returned 1:1 mapping between keys and columns

Great thanks in advance.
