I have galaxy server 15.10 running on Ubuntu 14.04, which has python
I was in the process of adding matplotlib from the toolchest. It has a
dependency on package_python_2_7.
Before proceeding, I'd like to understand a bit how that works. Does that
install a whole new python, and how then does it get invoked?
I have a limited understanding of Galaxy compared to Gildas and many
others here, but it seems that Galaxy and its tools are separated from
the rest of the system. So, installing a tool won't affect the system
unless your users have set a PATH to Galaxy's tool directory.
For example, when it installs the bwa tool, a bwa executable will get
installed deep within Galaxy's directories. But as long as your users
set their PATH to /usr/bin or /usr/local/bin or wherever you may have
bwa installed, they'll be fine. We have this setup where the server
that runs Galaxy also serves users via ssh. So far, so good --
Galaxy's tool installations don't seem to affect the system's packages
(whether it is something minor like bwa or major like Python). I'm
afraid I don't know how it is invoked behind-the-scenes, though.
The only issue I've encountered so far is the other way. Software
installation into the system affects Galaxy. This was the case with
Samtools and it happened to me just a couple of months ago. You can
take a look at my question and the many helpful replies I got here:
. It seems to be the case of just samtools for me (so far).
I hoe this helps!
