These are the famous Uppsala Software Factory programs, rescued into GitHub. Programs in the Uppsala Software Factory were written by Gerard Kleywegt, then at Uppsala and now at the EMBL-EBI.
The original README is in the file __README, but is out-of-date!
This Github repository contains the set of programs for crystallographic map and model manipulation in various subdirectories. Utility routines are in the subdirectory gklib, and are compiled into a library libgk.a Many of the programs also rely on CCP4 libraries, distributed as part of the CCP4 suite (www.ccp4.ac.uk).
Old binaries for Linux and OSX are in the directory OLD_BINARIES but there is no guarantee that they will work.
I am working on an updated Makefile Makefile_with_CCP4 but progress is slow (this is not my day job!). At some point, I will include a directory of static 64-bit executables for Linux.
