Leginon

h1. Minimum Requirements and current NRAMM setup

h2. Electron Microscope with its Controling Computer (Windows)

FEI Tecnai 12 with Scripting SW, network connected see [[Network Configuration]], and the ability to install software on it

h2. CCD

Gatan,  Tietz, Eagle-minimal 1kx1k; NRAMM 4kx4k

h2. A Second Computer Running Linux (CentOS at NRAMM)

At NRAMM, we separate the three activities into different computers that serve about 15 people with three microscopes that could be running at the same time.  All scopes share the same database, web server, and file server.  Each microscope has its own processing computer.

h3. CPU

Minimal 2 GHz;

NRAMM:

* Processing server: Single quad core (Intel Xeon E5540 2 2.53GHz).  One computer per microscope.

* Database server: Duo quad core (2.6GHz)

* Web server: Single quad core (Intel Xeon 3.00GHz)

h3. RAM

Realistically, you will need 4GB memory for all processing+database+web server activities for one microscope operation with 4k camera that serves two persons (one operates the scope, one just look at the images from the web viewers) at the same time.

At NRAMM, to serve about 15 people viewing images and with three microscopes that could be running at the same time:

* Processing server: 4GB physical memory and 2 GB swap for years, and now at 6GB and 6GB, respectively.  One computer per microscope

* Database server: 16GB memory and 1GB swap.

* Web server: 4GB memory and 6GB swap.

h3. Hard drive

10 GB for the softwares and maybe a few hours worth of data collection. Much larger

for routine use. NRAMM 15Tb and growing

h3. Network connection speed

100 Mbps might be possible; NRAMM 1 Gbps

h2. Leginon system components developed at Leginon home

Leginon Home:  "http://www.leginon.org/":http://www.leginon.org/

h2. Supporting packages and programs available through internet or your Linux distribution

There are minimum of ten packages or single programs, some of them are included in your

Linux distribution.

h2. Leginon supporting programs available upon request

adaexp.exe that is required if film exposure is to be made through Leginon on FEI Tecnai

machines is available by request. Please contact Max Otten: <email>mto@nl.feico.com</email>

and let him know what version of the Tecnai user interface you are using.
