New fortran computer programs to acquire and process isotopic mass spectrometric data

This report describes in some detail the operation of newly written programs that acquire and process isotopic mass spectrometric data. Both functional and overall design aspects are addressed. The three basic program units - file manipulation, data acquisition, and data processing - are discussed in turn. Step-by-step instructions are included where appropriate, and each subsection is described in enough detail to give a clear picture of its function. Organization of the file structure, which is central to the entire concept, is extensively discussed with the help of numerous tables. Appendices contain flow charts and definitions of variables to help a programmer unfamiliar with the programs to alter them with a minimum of lost time. 12 figures, 17 tables
