EMAN2 Programs

UNDER CONSTRUCTION - Seriously. We are adding to the detailed docs every week. If you don't see what' you're looking for, please email us and ask, and we'll move it up in the queue.

Note that running any EMAN2 program with the '--help' option will provide basic documentation for that program.

Generic Docs

• Standard parameters accepted by multiple programs

Important Utilities

• e2proc2d.py - Generic 2-D image processing

• e2proc3d.py - Generic 3-D image processing

• e2bdb.py - Examine and manipulate EMAN2 database files

• e2iminfo.py - Examine image files

• e2display.py - Main program for 2-D and 3-D visualization and interactive manipulation

Interacting with Other Software

• Frealign

  • e2refinetofrealign.py - Use an EMAN2 refinement result to set up all necessary files to start a Frealign refinement.

  • e2runfrealign.py - Execute Frealign based on the results of e2refinetofrealign.

  • e2refinefromfrealign.py - Collect the results from a standard Frealign run and re-interpret in EMAN2 terms.

• Relion

  • e2refinetorelion2d.py - Use Relion to perform maximum likelihood 2D Class Averaging.

  • e2refinetorelion3d.py - Use an EMAN2 refinement result to set up all necessary files to perform a Relion refinement.

Single Particle Tomography

• e2tomoboxer.py - Tomographic particle picker.

• e2classaverage3d.py - Tomographic class-averager. Will align and average stacks of (optionally classified) 3-D particles.

Low Level Tasks

• e2scannereval.py - Tool to look for scanner artifacts (film) or localized distortions (CCD frames)

• e2classaverage.py - Generate 2-D class-averages from sets of classified particles

• e2classextract.py - Extract particles associated with class-averages in various ways

• e2ctf.py - Contrast transfer function estimation and correction
