What this means is that patch_amber.py tried to contact
http://ambermd.organd wasn't able to connect within 10 seconds. If
you know it takes longer
than that to contact ambermd.org, try:
./patch_amber.py --update-tree --timeout 20
That will make patch_amber.py wait 20 seconds before giving up.
Another possibility is that you have to connect to the internet via a proxy
server -- do you know if this is the case? You can set the environment
variable http_proxy like so:
export http_proxy="
http://username:password.proxyserver:port"
In this case, substitute your user name, password, the proxy server
address, and the port number (typically 800). I've done this, and it
allows patch_amber.py to connect to ambermd.org and download updates.
But I have internet access. In webpage

This is what you should do if you absolutely *cannot* get patch_amber.py to
contact ambermd.org to download the bug fixes. (Talk to your network
administrator for help). However, if it's absolutely impossible, what you
should do is set up the following folders in your home directory:
bugfixes/AmberTools/12.0
bugfixes/12.0
Then, download every bug fix for AmberTools 12 (from
http://ambermd.org/bugfixesat.html) and put them in the
bugfixes/AmberTools/12.0 directory. If you have Amber 12, do the same
thing for Amber 12 (but put in the bugfixes/12.0 directory). After doing
this, you need to change the patch_locs line in patch_amber.py like you
mentioned above. For example, if your home directory is /home/sanjib, then
those lines will become
patch_locs = ['file:///home/sanjib/bugfixes/AmberTools/12.0/',
'file:///home/sanjib/bugfixes/12.0//']
This will tell patch_amber.py to pull the files from your local filesystem
instead of the internet. Note, you will also have to comment out the
portion of the script that checks for internet access:
# Make sure we have internet access, since we'll need it from now on
try:
amberhome = urlopen('
http://ambermd.org')
amberhome.close()
del amberhome
except IOError, err:
if 'timed out' in str(err):
print >> sys.stderr, \
'Error: Could not connect to http://ambermd.org in %.2f
seconds' % (
opt.timeout)
else:
print >> sys.stderr, 'Error: No internet access!'
sys.exit(1)
This starts around line 828. (To comment it out, put a # at the beginning
of each line).
