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.
