## NCMI Workshop on Single Particle Reconstruction, Structural Variability and Modeling

### Oct 30 - Nov 2, 2015

We strongly recommend bringing a 3 button (or 2 button+scroll) mouse. While it is possible to survive with a trackpad or one button mouse, there are many things in EMAN and Chimera where having additional mouse buttons is VERY useful.

The official agenda is on the Workshop Page

Presentation notes from the Workshop (some of these have not been uploaded yet)

Video of selected sessions Our primary video recording mechanism failed to record audio, so we unfortunately have only the EMAN and Modeling tutorials recorded

Tutorials

• Please note that e2refine_split has been improved significantly since 2.12. Suggest an update if using this method.

Tutorial Data You will also need all of the demonstration data, which we will use when going through the tutorials:

Completed Tutorial Projects (large files)

Software used at the workshop:

• EMAN/SPARX 2.12 (or snapshot version released after Oct. 19, 2015) - (day 1 - 2) Required. Do not use an older version.

• Relion 1.4 (optional, day 2-3) - The Relion session will largely be a demo. See comments below.

• Chimera Daily Build Oct. 17 or later - For PDB viewing and Segger tutorial (day 4, specific version required)

• Warning: we are aware of an issue with Gorgon on Ubuntu. Will remove this warning when resolved. Other Linux variants should be fine, now.
• Gorgon - Gorgon Tutorial (day 4) Please install the appropriate binary AND Data-Sets.zip

• Phenix - (end of day 4) real-space refinement of models

• LKH Solver - (day 4 - pathwalker), required only for the pathwalker tutorial, see below

• OpenMPI and PyDusa (day 2-3) SPARX tutorial may also largely be a demo, see below

• Please insure that you meet the specific version requirements above for each software package. Tutorials will be tested only on these specific versions.
• Mac users - If you are running El Capitan on your Mac (10.11) you will find there are a few bugs specific to this OS version we have not managed to fix yet. It should still be possible to complete the tutorial, but you will encounter a few annoyances.
• OpenMPI/Pydusa - Most SPARX tasks require MPI to run correctly, and are normally used on clusters. It is possible to install MPI on a single laptop/desktop as well, and requires minimal work or configuration to do so, you will simply be limited to the number of CPUs available on your laptop. Much of the SPARX presentation will be 'demo style' rather than a formal tutorial anyway, so you will not miss too much if you don't get MPI configured. Instructions are available here.

• Due to the required computation for most Relion refinements, Sjors plans to run a demo-style session rather than a tutorial. However, if you install Relion, you may be able to experiment with it a bit during the session. This is recommended only for users with Linux on their laptops.
• Chimera and Phenix have some restrictions on commercial use. If you work for a commercial entity, and your IT group will not install these packages, you will still be able to directly participate in most of the workshop. Phenix will only be used at the very end of day 4 to learn about real-space refinement. Chimera will be used on day 4 for a segmentation tutorial. It is also a useful utility to have available, but should otherwise not be strictly required.
• Warning - there may be some minor issues with EMAN/SPARX 2.12 on MacOS ElCapitan. If you have not upgraded, you may consider delaying until after the workshop.

• Installing EMAN2/SPARX:
