     31Note that version 1.41 or later of EXPGUI should be used with the April 2001
     32releases of GSAS on all platforms (Version 1.41 is currently the alpha
     33release version), due to changes in file formats and locations.
     34The "stable" release should be used
     35with older versions of GSAS.
    3438EXPGUI is a graphical interface for the

    338 LIVEPLOT gets the current diffraction information by running the TCLDUMP program, if installed, or
    339 HSTDUMP otherwise. The TCLDUMP program has been optimized for use with LIVEPLOT and offers a number of extra
    340 options that are not available when HSTDUMP is used: plots can be displayed in the native units (2Theta/TOF/KeV), or
    341 in d-space or Q; fixed plus fitted background curves are shown in green; if reflection tickmarks are displayed, <IMG SRC="new.gif" HEIGHT=13 WIDTH=36 alt="New!">
    342 reflection tickmarks can be displayed by pressing "H" or "h" while the
    343 mouse is near a reflection (holding the shift key while
    344 pressing the left mouse button also works).

    361407<h3>D.4 File Conversions</h3>
    363 <B>In UNIX</B>,
    364 GSAS data, experiment and instrument parameter files are expected to
    365 have a format with exactly 80 characters per line and no line
    366 separators (no carriage returns or linefeeds). Files in this format
    367 are called "Direct Access". Normal UNIX files may have any number
    368 of characters per line and every line is terminated by a line feed character.
    369 These files are called "sequential".
    370 EXPGUI uses the convention that all uppercase is used for Direct Access files
    371 while all lowercase is used for sequential files.
    372 <P>
    373 The Unix File Conversion menu is used to convert sequential files to
    374 direct access for use in GSAS or to convert direct access files to
    375 sequential, for use in standard UNIX programs, such as editors or e-mail.

    379411expected to have a format with exactly 80 characters per line followed
    380 by a carriage returns and a linefeed (82 characters total per line).
    381 Files in this format can be read in "Direct Access" mode. The Convert menu
    382 in windows can be used to convert files into this format (it can also

     413Files in this format can be read in "Direct Access" mode.
     414Recent versions of GSAS will attempt to detect and repair files that
     415are not in this format, but if the file is incorrectly formatted and
     416by chance the length of the file is divisible by 82, the problem in the
     417file format will not be detected.
     418The Convert menu
     419in can be used to convert files into the correct format.
