Can not parse metadata by providing the metadata file.

[thy-chan]

I'm trying to use 'gdcParseMetadata()' to parse metadata by providing the metadata file, but find that the format of the metadata file in GDC has been change recently.
So, I want to know how long the GDCRNATools can be updated.
Thanks!

@thy-chan Hi, could you please tell me the project you are trying to parse? Thanks

[thy-chan]

RNA-Seq files in TCGA-BRCA. The format of the metadata file has changed so that the GDCRNATools can't parse it.

@thy-chan Thank you so much for the reminder. I have just checked the JSON file in GDC and they do have changed the format. There's very little information in the file now, so I recommend that you can parse metadata use the automatic mode (eg., meta <- gdcParseMeta(project.id='TCGA-BRCA', data.type='RNAseq'), and then select the sample you'd like to use. Thanks

Yes, the information in the GDC's JSON file is reduced. I think the GDC extracts other information separately and puts it in other files, such as the Biospecimen and Sample sheet in the screenshot. Thanks

Parsing the metadata using the automatic mode for the TCGA-BRCA project does unfortunately not seem to work either:

> metaMatrix <- gdcParseMetadata(project.id='TCGA-BRCA', data.type='RNAseq')
Error in vapply(seq_len(nSam), function(i) null2naFun(metadata[[i]]$cases[[1]]$demographic$gender), :
values must be type 'character',
but FUN(X[[297]]) result is type 'logical'

I got a same error when parsing TCGA-COAD metadata, here it is:

HI, is this because of my internet problem?
or?
thank you very much

metaMatrix.MIR <- gdcParseMetadata(project.id = "TCGA-LUSC",

•                                data.type  = "miRNAs")

In addition: Warning message:

I got an error when automatic download RNAseq data, here it is:

thank you very much
