About a month ago I was able to download PubChem RDF files from the ncbi ftp site. Now I am unable to do so. Also tried a week ago without success. Here's the ftp folder:
ftp://ftp.ncbi.nlm.nih.gov/pubchem/RDF/
Even if I copy-and-paste a command straight from the pubchem website, that no longer works. The commands are from the "PubChemRDF Use Cases" section of the following page:
https://pubchem.ncbi.nlm.nih.gov/rdf/#_Toc421254667
For example, the following command typed into a linux shell should download the pubchem gene data (one relatively small file):
wget -r -A ttl.gz -nH --cut-dirs=2 ftp://ftp.ncbi.nlm.nih.gov/pubchem/RDF/gene
It looks like a new version of pubchem files was put in place on March 25. So perhaps something was changed then.
Just going in with command-line ftp I can navigate through the directory structure. I'm able to download a file from a neighboring directory, but not under the pubchem/RDF directory. Depending on what method I use, I get error messages like "permission denied" or "no such file".
Anyone know what's wrong, what has changed?
Thanks,

Thanks for the quick response.
Bad "read permissions" were my initial guess, though the file permissions and ownership settings looked exactly the same as for files that would load.
I wasn't finding a forum or any place to ask questions or report issues. But I went back to the site and tried again, and this time I eventually found a link to the help desk at the bottom of the page. As I report below, that worked.
