Using HippoDraw on SLAC Linux Systems

HippoDraw is installed at SLAC for use by Red Hat Linux 9 and Red Hat Enterprise Linux 3 machines. This includes both SLAC Computing Services (SCS) public machines (noric-new) and desktop machines maintained by SCS.

If you have a SLAC UNIX account, you can log into a public machine as shown below.

> ssh noric-new
RHEL WS release 3 (Taroon Update 1) 2.4.21-9.0.3.ELsmp (2x1390MHz Intel)

Using HippoDraw as a stand a lone application.

For use as a stand a lone application, HippoDraw has been installed in the GLAST I&T SVAC group's NFS file system. Once can start the application as shown below

noric13> /nfs/slac/g/svac/local/bin/hippodraw
Running on a Pentium

One clock tick corresponds to 7.19057e-10 seconds

Note that no environment shell variables need to be set. If you use HippoDraw often, you may want to add the path /nfs/slac/g/svac/local/bin in your PATH environment variable.

See Getting Started with HippoDraw for help in learning to use HippoDraw.

Using HippoDraw as a Python extension moudle.

HippoDraw has been installed in /usr/local/lib/python2.3/site-packages, the standard location for Python extension modules. To start a session with HippoDraw, first start the Python interactive shell as shown below.

noric05> python
Python 2.3.3 (#1, Apr  7 2004, 09:31:28)
[GCC 2.95.3 20010315 (release)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 

Next, import HippoDraw into the Python session as show below

>>> import hippo
Running on a Pentium

One clock tick corresponds to 7.19057e-10 seconds
__main__:1: RuntimeWarning: Python C API version mismatch for module hippo:
This Python has API version 1012, module hippo has version 1011.
>>>

Don't worry about the warning, SCS made a slight error in installing Python which may be already fixed by the time your read this.

The last step is to create the HippoDraw application as show below

>>> app = hippo.HDApp()
>>>

You'll more likely be putting these commands in a file and have Python interpret them at startup. For examples, eee Python scripts for more infromation.
