Dear All,

I'd like to know if there is anyway to download a certain structure file from http://www.pdb.org/. I tried the following but failed:

tmp <- download.file(url="ftp://ftp.wwpdb.org/pub/pdb/data/structures/all/pdb", destfile="pdb100d.ent.gz")

trying URL 'ftp://ftp.wwpdb.org/pub/pdb/data/structures/all/pdb'
Error in download.file(url = "ftp://ftp.wwpdb.org/pub/pdb/data/structures/all/pdb",  : 
        cannot open URL 'ftp://ftp.wwpdb.org/pub/pdb/data/structures/all/pdb'

Any tips to fix it please? Thanks in advance.

Best,
Baoqiang
