[3dem] Ettention 1.0 Released

[Tim]

Dear All,

we would like to point out the release of a new software package for 
electron tomography, called "Ettention". The software was developed over 
the last couple of years at the German Research Center for Artificial 
Intelligence (DFKI) in Saarbrücken, Germany, in cooperation with the 
company EYEN SE, Prague, and Maastricht University.

Ettention is released as open source on the platforms Windows and Linux. 
It requires a OpenCL compatible high performance computing (HPC) 
backend, such as
- NVidia GPU, or
- x86 CPU with OpenCL driver installed, or
- Intel Xeon Phi

Use Cases so far:

Ettention provides support for typical iterative reconstruction methods 
such as block iterative reconstructions and SIRT and comes integrated in 
the eTomo User Interface of IMOD. It has been used in the NOTOX 
(FP7-267038) project for cryo-EM reconstructions of single tilt CTEM data.

Ettention provides a STEM plugin for the reconstruction of combined 
tilt- and focal series data in aberration corrected STEM with limited 
depth of field.

A laminography plugin has been used in the course of the IMCL project 
(AOBJ: 600875) for X-Ray Laminographic reconstructions using geometric 
prior knowledge.

The main point of Ettention is that, due to a modular design and object 
oriented architecture, the system is very extensible and therefore well 
suited for algorithmic experiments. The software automatically takes 
care of memory mangement on the HPC device and therefore is suitable for 
high resolution reconstructions (2K and more). Ettention is shipped with 
numerous tutorials and examples inclusing implementations of the 
weighted back projection, weighted SIRT and a tutorial demonstrating the 
use of geometric prior knowledge.

Ettention can be downloaded from www.ettention.org 
<http://www.ettention.org> or https://github.com/c3di/ettention.git. 
Please feel free to use the software and provide us feedback via 
contact at ettention.org <mailto:contact at ettention.org>.

A first hands-on experience on Ettention will be given during the 
cryo-EM workshop in Maastricht, July 8-10.


We thank David Matronarde and Sue Held for their help integrating 
ettention in the eTomo GUI.

best regards

The Ettention Team
