1. Scipion: Toward software integration, reproducibility and validation in EM image processing Biocomputing Unit, Instruct Image Processing Center, CNB-CSIC J.M. de la Rosa Trevín

2. There are different EM modalities Single Particles Helical 2D Crystallography Tomography

3. There is a long path to produce a 3D model Sample Preparation Image Acquisition 3D reconstruction 3D model 2D Analysis

4. Image acquisition and preprocessing Data collection Movies alignment (with DDD) Micrographs CTF estimation

5. 2D image processing for Single Particles Particle Picking Screening - Preprocessing Alignment and Classification

6. 3D reconstruction Initial model 3D classification 3D refinement VALIDATION

7. The EM field needs software integration Using different EM software packages is now like the tower of Babel

8. Appion is certainly a pioneer work in terms of software integration (and our main inspiration) Appion is certainly a pioneer work in terms of software integration (and our main inspiration) It is increasing the number of external tools added to current EM packages (such as Eman2, Xmipp3 or Relion ) It is increasing the number of external tools added to current EM packages (such as Eman2, Xmipp3 or Relion ) But still is complicated to easily use tools from different packages in one project…

9. Scipion goals 1.Integrate EM software packages to be used in the same project. 2.Full project traceability, improving reproducibility. 3.Execute complete workflows in an automated manner. 4.Easy to install and use. 5.Easy to extend with new protocols.

10. Goal 1: Integrate EM software packages to be used in the same project. Goal 1: Integrate EM software packages to be used in the same project.

11. All vs All is hard to maintain and extend All conversions: N*N New package: 2*N

12. It is better to have a common format All conversions: N+N New package: 2

13. We bridge across package differences by modeling our domain 3D Reconstruction Set of Images Initial Model 3D Volume Data Protocols

14. We need conversion functions for each package

15. Goal 2: Full project traceability, improving reproducibility. Goal 2: Full project traceability, improving reproducibility.

16. Results should be reproducible, not more “black boxes”

17. We implemented a simple storage mechanism Mapper Layer Data Objects Protocol Objects

18. Goal 3: Execute complete workflows in an automated manner. Goal 3: Execute complete workflows in an automated manner.

19. Scipion client Worker Host 1 Worker Host 2 Scipion Server Bookeeping Designed to perform distributed execution Distributed data storage Big data transfers

20. Goal 4: Easy to install and use. Goal 5: Easy to extend with new protocols. (Let´s see Scipion in action) Goal 5: Easy to extend with new protocols. (Let´s see Scipion in action)

25. Roadmap 2015 May : Alpha release Pilot installations outside Madrid. (A few have been made already) June : Beta release announcement in 3DEM list End of summer : Scipion 1.0 release

26. There is a team behind

27. We need to do it all together!!! All are wellcome.
