[modeller_usage] Using modeller with a web form: how topass the provided key to modeller?

[Stéphane Téletchéa <>]

Hello,

I'm planning to provide models from carefully validated alignments and 
in order to provide this tool, i would like to allow users to access to 
the full model, and produce new ones using my methodology, from a web 
server.

According to the policy, http://salilab.org/modeller/FAQ.html#18, i must 
use a form and use this key for launching modeller (i totally agree with 
this).

However, how can i use this license?
In fact, if i install modeller the standard way (on linux, using 
http://salilab.org/modeller/9v6/release.html#rpm):
env KEY_MODELLER9v6=XXXX rpm -Uvh modeller-9v6-1.i386.rpm, then the key 
is incorporated in the installation.

In this case, the "external" key is not used (mine is taken).

On the other end, if i install modeller without the key (remove the env 
KEY_MODELLER9v6=XXXX to the above command), i receive:

KEY_MODELLER9v5=<VALIDKEYHERE> /usr/bin/mod9v5 file.py
Traceback (most recent call last):
 File "<string>", line 1, in ?
 File "/usr/lib/modeller9v5/modlib/modeller/__init__.py", line 65, in ?
   _modeller.mod_start()
_modeller.ModellerError: check_lice_E> Invalid license key: xxx
Go to http://salilab.org/modeller/ to get a license key,
and then set the 'license' variable to it in the file
/usr/lib/modeller9v5/modlib/modeller/config.py


I have tried various combinations to set the KEY_MODELLER9v5 (env, 
export, in a sourced file, etc) but i'm always stucked.

Any idea ?

Thanks a lot in advance,

Stéphane Téletchéa
