SPHIRE 1.3

We are happy to announce the release of SPHIRE 1.3.

What's new

Helical processing with SPHIRE 1.3
Per particle CTF refinement. The image shows a refinement of appoferritin dataset with tilted stage. The refined defoucs values (left side) clearly shows the tilt axis. The right side is the a error estimate for every defocus value.
crYOLO can now directly used from SPHIRE 1.3
  • Hands free processing with AutoSPHIRE: While the individual steps can be configured and executed by hand, SPHIRE 1.3 includes AutoSPHIRE, an integrated tool that enables SPHIRE to run without the need for user supervision up until the creation of a high resolution reconstruction.
  • Per particle CTF refinement with error estimation. When you reach a resolution of about 4A you can refine your CTF on a per-particle basis. This can improve the resolution by 0.3A or more.
  • Integrated crYOLO 1.5 for particle picking. crYOLO is based on convolutional neural networks, and can accurately pick about ten micrographs per second.
  • Integration of automatic 2D class selection with CINDERELLA. This tool is based on a deep learning network to separate 2D classes from .hdf / .mrcs files into good and bad classes. It uses the same deep neural network as crYOLO and comes pre-trained on a set of good and bad classes. Cinderella was written to automate cryo-EM data processing.
  • The new compare re-projections tool can now be used to produce side-by-side comparisons of the 2D class averages with the respective projections of the initial 3D model.
  • Visualization of 2D power spectra in CTER
  • Minor bug fixes

Tutorial

Download

The installer uses Anaconda, which should install independently of the choice of Linux distribution. The Mac installer is experimental.

Here are the downloads for Max and Linux:

SPHIRE does not support Windows

These external tools will be needed to run all tools in SPHIRE:

TranSPHIRE for automatated preprocessing

Furthermore, we recommend to use TranSPHIRE for automated preprocessing: TranSPHIRE GitHub page
