TCGA data Query (GDCquery): external_gene_name " are missing
I just got some weird output from TCGA dataset. As you can see in the below picture, some of the "external_gene_name " are missing. Would you please help me out with this issue? Thank you.
query.seq <- GDCquery(project = "TCGA-BRCA", data.category = "Transcriptome Profiling", data.type = "Gene Expression Quantification", sample.type = c("Solid Tissue Normal", "Primary Tumor"), workflow.type = "HTSeq - Counts") GDCdownload(query.seq) seq.brca <- GDCprepare(query = query.seq, summarizedExperiment = TRUE)
