Hi,
The following code used to work until yesterday evening (March 20th 2024).
The code downloads the PAAD TCGA data and extracts the z-score expression table.
Now, the loaded z-score expression table is filled with NA
. There are also warnings during the download.
Has something changed in the way I should load this table?
Many thanks, Astrid

Hi Astrid,
I took a look at the
data_mutations.txt
and it looks like theEntrez_Gene_Id
column is allNA
.FWIW, you can use
downloadStudy
and thenuntar
to investigate the data in the files.Note that
paad[["mutations"]]
is aRaggedExperiment
and it only represents the first column in themcols
.To represent a different column, you can use the
i
argument inassay
:For more transformations, see the
RaggedExperiment
vignette and the?RaggedExperiment::
`assay-functions
` documentation page.Best regards,
Marcel
Hi Marcel,
Thanks for the quick answer.
To look at the z-score expression, I need to extract
experiments(paad)[6]
instead ofexperiments(paad)[8]
.Has the order changed?
Best, Astrid
Hi Astrid,
Please always use named rather than numeric indices. It avoids issues as above. For me, experiment #8 is
mutations
.I suppose you meant to refer to :
