Dear all, I am trying to do methylation analysis on TCGA data using TCGAbiolinks.

Since I only wanted to use a limited subset of samples, I used their TCGA codes in:

query.met.normal = GDCquery(project = "TCGA-THCA",legacy = TRUE,data.category= "DNA methylation",

platform = "Illumina Human Methylation 450",

barcode = c("TCGA-EM-A3ST-11A-11D-A231-05" ,"TCGA-FY-A3TY-11A-12D-A231-05" , ...)).

After downloading data which were saved in "C:\Users\Administrator\Documents\GDCdata\TCGA-THCA\legacy\DNA_Methylation\Methylation_Beta_Value", I used :

met.normal.450 = GDCprepare(query = query.met.normal,save= TRUE,save.filename = "normalDNAmet450k.rda" ,summarizedExperiment = TRUE),

however I got this error:

Error in rbind(deparse.level,...) numbers of columns of arguments do not match.

Can you guide me to solve this problem?

Kind regards

It is better to post TCGAbiolinks issues on the GitHub page:
