Getgeo Error

Question

[nazaninhoseinkhan]

Hi Thanks for comments, but the problem has not been solved yet. When I type this command: gds = getGEO('GDS2478'), I get the following error:

Error in download.file(myurl, destfile, mode = mode, quiet = TRUE, method = getOption("download.file.method.GEOquery")) : 
  cannot open URL 'ftp://ftp.ncbi.nlm.nih.gov/geo/datasets/GDS2nnn/GDS2478/soft/GDS2478.soft.gz'
In addition: Warning message:
In download.file(myurl, destfile, mode = mode, quiet = TRUE, method = getOption("download.file.method.GEOquery")) :
  InternetOpenUrl failed: 'The server name or address could not be resolved.

Could it be related to slow internet connection or something similar? Thanks anyway for your response. Nazanin

It would be better to use a comment thread at your original question to resolve these issues. You have now posted a variation of the same question 3 times.

Note: this and related questions are now resolved. Questioner posted the resolution as yet another question...with yet more unhelpful tags...which was deleted.

Your question has nothing to do with GEOquery, really. It looks like you are likely behind a firewall or do not have internet connectivity. Assuming that other software is able to connect to the internet, you will likely need to set up a proxy to get through your firewall. The help page for download.file documents this process.

Sometimes, getGEO ( even GEOquery 2.33.8) is really slow even loadings series_matrix file locally. Update: The reason is indeed the internet connectivity to GEO website is poor. I found getGEO must download GPL from internet if GPL=TRUE but cannot use local GPL file.

[Sean Davis]

GEOquery should use a locally cached GPL now (as of version 2.35.1 or later).

I had the same problem and this really worked for me. Thanks Sean.
