EMAN2 Introductory Tutorials
Please note that we are continuously developing and updating the tutorials. Most tutorials include the necessary data. If you have a request for a particular tutorial please feel free to email sludtke@bcm.edu .
Video tutorials and discussions
EMAN2 Video Tutorials - These are a valuable supplement to the tutorials here, but are NOT a replacement
Standard Tutorials
Tutorial Data Downloads
The actual tutorials are in the sections below, this section contains the various test data sets.
Individual tutorial data downloads are available below, but for convenience, we have combined the data for the GUI introduction, single particle analysis tutorial, single particle 2-D dynamics tutorial and small tomography tutorial into a single download:
Alternatively, these individual data downloads cover the following standard workshop tutorial sequence:
Short tutorials and info sheets
EMAN2/Jupyter - Using EMAN2 widgets from JupyterLab notebooks! (NEW - 2022)
EMAN2/NegativeStain - special issues that impact processing negative stain single particle images
Single particle analysis (SPA) - 2D particles
Quick Introduction to the EMAN2 GUI (Start here if you have never used EMAN2!)
tutorial for the Neural network particle picker (requires CUDA for good performance)
- These haven't been updated in a while, please ask if you have problems
EMAN1 to EMAN2 Transition Guide - Also with useful quickstart guides for users of other software
Tomography - tilt series through subtomogram averaging
- Complete workflow for tomography and subtomogram averaging (includes both small version (laptop ~12 Å) and large version (subnanometer on workstation))
- Automated Cellular Tomogram Annotation using Neural Networks
- More advanced topics for subtomogram averaging
Advanced SPT methods - Latest (2023) workflow for in situ SPT.
Working with pseudosymmetric particles - Improving resolution and exploring variability in symmetric particles
Miscellaneous tools - Various SPT tools that may not be included in the main workflows.
Gaussian Mixture Model - for SPA and SPT data
Heterogeneity analysis - Strongly suggest reading the paper (PMC8363932). While there have been some very significant improvements, it lays a foundation. This project has also bifurcated, as explained in the first tutorial below.
GMM GUI Tutorial - supports both SPA and SPT projects - suggest starting here for most users
Orientation refinement - Improve resolution for flexible structures. For detailed methods, see the 2024 paper.
GMM-based orientation refinement for SPA
tutorial on GMM based orientation refinement for SPT
Atomic model refinement - both single model and continuous movement.
