Large dynamic range small-angle diffractometer D22

Small-angle scattering is a technique that measures the deviation to small angles (much less than one degree to several degrees) of an X-ray or neutron beam due to structures of small size in the sample. “Small” means dimensions of a few tenths to about 100 nanometres, such as clusters in alloys, polymers, or biological macromolecules.

D22NIH_Image

NIH Image files

This document describes how to get and use a data file for/with NIH Image.

For other details, refer to the complete D22 Manual. See also the D22 documentation.

 

  1. On d22sgi (or another workstation), run w_image that produces "I" files (Irun.Iext, e.g. I10100.I01)
  2. FTP this file to the Macintosh, e.g. with Fetch
  3. Open NIH image
  4. IMPORT (File menu) the I file as TEXT
  5. Manipulate the I file

This procedure is relatively easy with NCSA Telnet, having two windows open, one for treating data on d22sgi, one for FTPing.
