Hello,

I am trying to normalize a dataset from the Geo site using the SCAN.UPC's UPC method, but it is giving me an error.

Here is my code:

eset <- UPC("GSE57338")

Here is the error:

Warning messages:

1: In download.file(file.path(url, i), destfile = file.path(storedir,  :

  downloaded length 4243712 != reported length 1421281280

2: In untar(tarFilePath, exdir = downloadDir) :

  ‘/usr/bin/tar -xf '/var/folders/k2/qp4ym_z11zv4wtk9yypxfxtr0000gn/T//RtmpMyCgHP/GSE57338_RAW.tar' -C '/var/folders/k2/qp4ym_z11zv4wtk9yypxfxtr0000gn/T//RtmpMyCgHP/GSE57338'’ returned error code 1

3: executing %dopar% sequentially: no parallel backend registered

Please advise on how I should fix this.

Thanks.

Hi Vani,

I just tried it on my server, and it worked fine. I got no errors. I was using the latest version (3.2.3) of R and SCAN.UPC (2.12.1). Can you please make sure you are on the latest versions and try it again? If you get another error, please send the full output as well as output from sessionInfo().

Thanks,

-Steve
