tomato is a  is a  program for the three-dimensional object reconstruction from a series of projection images. The program was designed to address specific issues of the refinement of the reconstruction.  It includes common approaches for the reconstruction procedure as well as a graphical user interface. It is therefore useful also in a productive environment. So far, tomato reconstructs from single axis tilt series. tomato is written in the IDL programming language which supports Apple Mac OS X, LinuX and Windows. A valid installation of the freely distributed IDL virtual machine is required. Visit the IDL website for further information.
The free version of tomato includes the following features:

• import of three-dimensional data stacks in mrc format 
• export to mrc or animated gif format
• multiple data stack handling
• simple data stack manipulations
• sub-pixel accurate cross-correlation alignment
• interactive refinement of alignment properties (tilt axis offset, rotation, drift)
• projection and back projection based on the 2D Radon transform
• weighted back projection

The licensed version of tomato includes the following features:

• refinement routines based on grid search algorithms and pseudo-projections
• simultaneous iterative reconstruction technique
