Appion

h1. Start with existing CentOS 5.3 64-bit installation

{{>toc}}

h2. 3 Download additional software 

h3. 3.1 Install the additional package repositories 

*NOTE*

There are several additional CentOS repositories that you can install.

These repositories provide additional packages, such as patented software (MP3 players),

closed source applications (Flash plugin, Adobe Acrobat Reader)

and lesser used packages (python numpy, Gnu Scientific Library).

But some repositories install packages over other packages,

which can cause problems and conflicts (ATrpms is bad at this). So I recommend only installing

EPEL and RPM Fusion. Read more here:

"CentOS Additional Repositories":http://wiki.centos.org/AdditionalResources/Repositories 

h4. 3.1.1 Extra Packages for Enterprise Linux (EPEL) 

* http://fedoraproject.org/wiki/EPEL

* contains a wealth of packages required for appion

.Download repository rpm and install

<pre>

$ sudo rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/`uname -i`/epel-release-5-3.noarch.rpm

</pre>

h4. 3.1.2 RPM Fusion 

* http://rpmfusion.org/

* good for mp3 and other patent limited software

.Download repository rpms and install

<pre>

$ sudo rpm -Uhv http://download1.rpmfusion.org/free/el/updates/testing/5/`uname -i`/rpmfusion-free-release-5-0.1.noarch.rpm

$ sudo rpm -Uvh http://download1.rpmfusion.org/nonfree/el/updates/testing/5/`uname -i`/rpmfusion-nonfree-release-5-0.1.noarch.rpm

</pre>

h3. 3.2 Update current packages 

.Update the updater to make life easier

<pre>

$ sudo yum -y update yum

</pre>

.Update all packages

<pre>

$ sudo yum -y update

</pre>

*NOTE*

Download was over 129 MB (in July 2009). If you have a slow internet connection you can setup presto/deltarpms, "see this email]":http://www.linux-archive.org/centos-development/222706-presto-deltarpm.html 

You may want to restart your computer when this completes.

h4. .Install Complete list of additional packages:

* *python tools*: python-tools python-devel

* *general applications*: subversion ImageMagick grace gnuplot python-matplotlib

* *Tilt Picker*: wxPython numpy scipy python-imaging

* *FindEM*: gcc-gfortran compat-gcc-34-g77

If you have an nVidia video card and setup RPM fusion, install the nVidia binary, will speed things up especially for UCSF Chimera

<pre>

$ sudo yum -y install nvidia-x11-drv

</pre>

.Clean up packages to save drive space

<pre>

$ sudo yum clean all

</pre>

.Re-index the hard drive, this will come in handy later

</pre>

You should see mrc.so listed.

h4. Make sure that GD and FFTW 3 libraries are installed

* edit your  php configuration file php.ini to add "mrc.so" extension.

* You might also increase the memory_limit field. It is set to 8M by default. The more the merrier!

* 4kx4k float MRC image is about 64MB

<pre>

> vi /etc/php.ini

</pre>

* increase memory

<pre>

> memory_limit = 256M; Maximum amount of memory

</pre>

* Create the mrc.ini file

<pre>

> cd /etc/php.d

vi mrc.ini

</pre>

* add the following lines

<pre>

 ; Enable mrc extension module

 extension=mrc.so

</pre>

*NOTE:* If PHP modules are already listed in PHP.ini do the following:

* check extension_dir value

<pre>

 extension_dir = /usr/lib64/php/extensions

</pre>

* add the following at the end of the [extension section]

<pre>

 extension=mrc.so

</pre>

h4. Restart your webserver

*TODO: Place link to file here!*

h3. 5.1 Compile FindEM 

* Goto appion/findem folder to make findem.exe

* Compile the libraries and binary

<pre>

$ make

</pre>

* Test findem.exe to see if it runs

<pre>

$ make test

</pre>

*WARNING*

Only if the first part fails, you must add the path to libg2c.so library file.

Otherwise skip to next section.

* locate libg2c.so library file

<pre>

$ ls /usr/lib/gcc/`uname -i`-redhat-linux/3.4.6/libg2c.so

</pre>

<pre>

$ locate libg2c.so

</pre>

* Edit Makefile with location of libg2c.so

* Re-compile

h3. 5.2 Compile Ace2 

The 64 bit Ace2 binary is already available in the myami/bin directory. 

Test it by changing directories to myami/bin and type the following commands:

<pre>

$ ./ace2.exe -h

$ ./ace2correct.exe -h

</pre>

Notice the help display.

<pre>

If this does not work or you wish to compile it yourself follow the instructions here.

NOTE:

ace2 typically requires fftw 3.2 or greater. This is significantly faster than 3.1 (which is distributed with CentOS). 

There is a FFTW_WISDOM_ONLY flag in Image.m that can be commented in if you are using fftw 3.2 or greater.

*TODO: Can we have the make file detect which version is installed?*

* Goto myami/appion/ace2

* compile the libraries and binary

* test to see if program runs

$ make

$ ./ace2.exe -h

$ ./ace2correct.exe -h

$ python

</pre>

<pre>

>>> import radermacher

>>> <Ctrl-D>

</pre>

h3. 5.4 Test Appion 

* Go into the appion directory

* Add myami to PYTHONPATH if myami is built locally (in home directory)

*TODO: what does this mean?*

<pre>

$ export PYTHONPATH="/your-complete-path-to-myami:$PYTHONPATH"

</pre>

* Add appion to PYTHONPATH

<pre>

$ export PYTHONPATH="/your-complete-path-to-myami/appion:$PYTHONPATH"

</pre>

*TODO: Consider moving appionlib so you only need to set one path.*

* Run the test script

h2. 9 Install a PBS job submission system

You'll need to install a "Portable Batch System":http://en.wikipedia.org/wiki/Portable_Batch_System for job submission, such as "TORQUE":http://en.wikipedia.org/wiki/TORQUE_Resource_Manager . I know Torque comes with Fedora 10, but not CentOS.

* An RPM is available in the EPEL testing section

<pre>

$ sudo yum -y --enablerepo=epel-testing install torque

</pre>

or another way to get packages

<pre>

$ wget http://centos.karan.org/el5/extras/testing/`uname -i`/RPMS/torque-2.1.9-1.el5.kb.`uname -i`.rpm

$ sudo yum -y localinstall --nogpgcheck torque-2.1.9-1.el5.kb.`uname -i`.rpm

$ #sudo rpm -Uhv torque-2.1.9-1.el5.kb.`uname -i`.rpm

</pre>

After installing torque it needs to be configured. Sorry, we have no documentation for configuring torque at this time. You may try http://www.clusterresources.com/products/torque-resource-manager.php
