  Administration: Regular working group meetings were organised during Q2 and Q4 of 2014; a series of developers workshop have continued on a quarterly basis: 14 Jan 2014 and 20 May 2014 in Birmingham; 22 July 2014 at Nottingham and 22 October 2014 in QMUL; and we also assisted and presented in the second Tomography for Scientific Advancement symposium (ToScA) in the Natural History Museum (1-3 Sep 2014) involving a stand and keynote talks. The extra monthly showcase meetings involving software show-and-tells is organised at RAL and has continued with 18 events in the series (total attendance 290); including at the end of 2014 two recorded sessions (56 external views). There have been an exhibition stands and presence at various events including in Q1 2015 the first touchtable activity point.

Collaboration: After a CCPi Seminar in Nov 2013, work started with CCP-ASEArch in April 2014 by Evgueni Ovtchinnikov; involving numerical methods, to apply a multigrid solution to improve the issues caused by gradient based regularization coefficients in order to accelerate and stabilise convergence. This has now resulted in a publication to be submitted after collaboration with Daniil Kazantsev (CCPi Flagship Fellow). With the ISIS Neutron Spallation source we have put together a package with an extra 2.0 FTE to create a new tomographic framework for the IMAT beamline due to be in opperation as a service in Q2 2015 (Inialial tests complete in Q4 2014). With Diaminad Light Source we are assisting in constructing their new framework "Sabu" that is under test Q1 2015, and due for release in Q3 2015.

  Publications: Related to the code integrated, with the flagship project, within the CCPForge, three papers have been accepted by Daniil Kazantsev including attendance at the Applied Inverse Problems conference, 2015 in Helsinki; and the Royal Society Phil Trans A special edition now has a complete set of titles and authors (nine papers), with seven currently under peer review: Theme Issue is titled "X-ray Tomographic Reconstruction for Materials Science".

Training etc: A series of courses have been coordinated and software supported; including licenses servers, have assisted with the Diamond Light Source, Research Compex at Harwell and University of Manchester: four multi-day courses held annualy at RAL and four multi-daty courses held at Manchester and a specialist annual course at SCD/STFC: including a Christmas lecture.

  Development targets met in year for CCPi up to January 2015:

  • The exisiting quantification algorithms have all been revised into more portable formats. This has allowed them to be made available in the three choosen packages (Avizo, ImageJ and ParaView) with a common source code base to improve maintainability.
  • The accessible volume algorithm has been improved and tested. It is now scales well to large image size.
 
  • Initial particle tracking code based on MXIF is complete with modifications now made to determine proximity of particles from one form to the next.

  • The histogram based thresholding methods has been implemented with extended versions planned for 2015 involving a four day developer's intense session (confirnmed Feb 17-20 2015).

  • The histogram based thresholding methods has been implemented with extended versions planned (quanification developer's workshop Feb 17-20 2015).
  • Work on a generalised implementation of a beam hardening algorithm is in progress in collaboration with Graham Davis (QMUL) and RaCH staff.
 
  • Iterative reconstruction development proceeds; a NeXus? reader for Diamond Light Source data sets is written and deployed; integrated with a CGLS code.
  • Test runs on Hartee systems for iterative methods continue but can require about 20hrs/iteration. The code has been modified to reduce memory requirements for workstations and the next stage is looking at alternative technologies.
  • A dedicated CCPi YouTube? channel continues to be exploited:http://www.youtube.com/channel/UCGB578xcyXNQyiBsufEFIeQ
