Manual

The following sections shortly describe how to run DATRG from the command-line on any of the supported platforms, the required input and runtime output

Introduction

DATRG is a tool for estimation of radius of gyration (Rg) and I0. It also estimates errors of determined values and fidelity.

Running datrg

Usage:

$ datrg [OPTIONS] FILE(s)

OPTIONS known by DATRG are described in next section, the required argument(s) FILE(S) in the section on input files.

Command-line arguments and options

DATRG requires the following command line arguments:

Absolute as well as relative paths to data files are accepted. Up to one of the input files may also be given as '-', in this case input is read from stdin instead of a file.

DATRG recognizes following command-line options:

Runtime output

DATRG output consists of results lines for each input file with the following values: Rg, error of Rg, I0, error of I0, fidelity.

datrg input files

FILE may come in any supported file format that provides a scattering vector, experimental intensity and experimental errors.

Example

$ datrg -t ROD --last 20 sample001.dat sample002.dat
