bin_stuff
command-line programs for performing mathematical operations on flat binary data files
X-ray data manipulation utilities
convert, add, subtract, multiply or whatever
These short programs are convenient tools for manipulating and interconverting flat data files of type float, int, or short. I wrote them to "hack" X-ray images and electron density map files, but you might find more tricks for them to perform. Documentation is divided by program, with cross-referencing between them:
description of X-ray file formats
Brief description of how SMV, CBF and CCP4 map files work, and how you can manipulate them.
int2float
Convert 16-bit integers, such as SMV-formatted images into floating-point for overlay of or combination with X-ray data.
floatgen
Convert text data into floating-point for overlay of or combination with X-ray data.
float_add
Add, subtract, scale and offset raw floating-point flat files with arbitrary headers.
float_func
Perform any C function on one or two raw floating-point flat files with arbitrary headers.
noisify
Add any kind of noise to floating-point flat files and output SMV-formatted X-ray data.
