h1. Minimum Requirements and current NRAMM setup *Recommendation is based on the 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 (Linux- CentOS at NRAMM) h3. CPU Minimal 2 1 GHz; At NRAMM, we separate the three activities into three computers: * Processing server: NRAMM 3 x (Intel Xeon E5540 2 2.53GHz) * Database server: Duo quad (2.6GHz) * Web server: 4 x (Intel Xeon 3.00GHz) h3. RAM Realistically, you Minimal 1 GB physical memory and 1GB swap but it will need 4GB memory be painfully slow 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 4kx4k images from the web viewers) at the same time. At NRAMM, we separate the three activities into three computers that serve about 15 people with three microscopes that could be running at the same time: * Processing server: and MSI applications; NRAMM had 4GB physical memory and 2 GB swap for years, and now at 6GB and 6GB, respectively. * 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; Mbps; 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. ______ [[Graphical User Interface|< Graphical User Interface]] | [[Getting Started|Getting Started >]] ______
