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:
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:
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?
