2010, Methods in EnzymologyCitation Excerpt :Parts of the original Fortran MRC software code can be found in several of today's biological image-processing tools, including those for processing noncrystalline specimens (see, e.g., Chapter 16). Spectra from the Ice package was a program that generated Unix Shell scripts that launched an early version of the MRC programs (Hardt et al., 1996; Schmid et al., 1993). Spectra contained its own image visualization program, and facilitated the use of the MRC programs.
Energetics and geometry of FtsZ polymers: Nucleated self-assembly of single protofilaments
2008, Biophysical JournalCitation Excerpt :The best images, as judged by optical diffraction, were digitized in a SCAI scanner (Zeiss, Jena, Germany) with a sampling window corresponding to 0.14 nm/pixel. Lattice refinement of the images was carried out using the X-windows-based graphical environment SPECTRA (56) and the subsequent image processing, including lattice unbending, was performed using the MRC image processing suite (57). Transfer function correction was carried out using the Integrated Crystallographic Environment (58).
Imaging Actomyosin In Situ
2007, Methods in Cell BiologyCitation Excerpt :Determine the reciprocal lattice vectors. We use a standard electron crystallography program, SPECTRA (Schmid et al., 1993), to determine these vectors, from which the real space lattice vectors will be determined. SPECTRA also computes the cross‐correlation map and fits a lattice to the centers of the correlation peaks if desired.
