cns2fsfour
converts a map output by CNS into a FSFOUR format readable by XtalView.

ccp2fsfour
converts a map output by CCP4 into a FSFOUR format readable by XtalView.

brix2fsfour
converts a BRIX format map into a FSFOUR format map readable by XtalView.

int2fobs.com
converts a SCALEPACK file into XtalView .fin file, CNS reflection file, and .mtz file. F's are generated through the CCP4 program TRUNCATE.

resfilter
reads in an XtalView reflection file (.fin, .phs, .df) and writes out reflections based on resolution.

sigfilter
reads in XtalView reflection files and outputs those that pass a sigma cutoff criteria.

SHELX97 restraint utility restraint
Generates the 1,2-distance (DFIX_*) and 1,3-distance (DANG_*) from a PDB file to generate restraints for non-standard residues for SHELX97 structure refinement.

bibliography tools
Tools for converting between Medine/BibTex/Reference Manager/EndNote. These tools supercede med2bib, bib2ris, and bib2en and contain bug fixes not found in them.

gentex
Script to generate a "Bibliography Key" that displays all references within a text file with the appropriate Bibtex identifier to make sure that the formatting of a Bibtex file is properly performed.

ck2phylip
Converts a SEQUOIA/CKWHENCE alignment into a file readable by the PHYLIP phylogeny package.

timeout
The UNIX networking command that should have been. Times out any command entered on the command line after a set number of seconds.

cut and paste
Cut and paste are a set of vanilla ANSI C utilites designed to breakup (and reform) large files into smaller pieces to transfer via FTP or onto small-capacity media formats.
