Hi, I want to download the RNA-seq data from the TCGA website. After I built the data matrix on the TCGA website, there are hundreds of the checkboxes. However, I only want to download the ones with the specific name rsem.genes.normalized_results, because I only needed the normalized data. It is too time-consuming to click one by one. Could anyone help to show me some more simple way to do it? Thank you so much!

How to select checkboxes would be some kind of Javascript or client programming question. We don't need to solve this obscure problem, when the root issue was how to download a lot of TCGA normalized data. See this program instead to easily download what you need without using their website.

Hi Karl, Thanks so much. I've downloaded the TCGA-Assembler, however, after I installed the Rtools31 and downloaded the httr version 0.5.0., and tried to type install.packages("httr_0.5.tar.gz", type="source", repos=NULL)
it turned out that
"ERROR: dependency 'jsonlite' is not available for package 'httr'
* removing 'C:/Program Files/R/R-3.2.0/library/httr'
Warning in install.packages :
running command '"C:/PROGRA~1/R/R-32~1.0/bin/x64/R" CMD INSTALL -l "C:\Program Files\R\R-3.2.0\library" "httr_0.5.tar.gz"' had status 1
Warning in install.packages :
installation of package 'httr_0.5.tar.gz' had non-zero exit status"
Could you help to tell me how to solve this problem? Thank you so much!

That's a computer problem, maybe your IT admin can help install the packages. It's a common enough issue with R packages. Read the error message, "dependency jsonlite is not available"
So first you'll have to install.packages("jsonlite") and it should download from CRAN automatically.
I tried it now, httr also wants a package called "R6" which was installed automatically when completing
install.packages("httr")
You don't have to specify repos=NULL, and it will download for you.
