- 12th March 2003: New updates of OrientExpress, Celref, Chekcell, Indx and Poudrix
- OrientExpress (Orient a single crystal of known unit cell dimensions from a single Laue pattern)
- When the sample crystal to be oriented has a rhomboedral cell,
OrientExpress always prefers to work with the basic rhomboedral cell for
the determination of the crystal orientation rather than with the triple
hexagonal cell, this last description involving generally higher Miller
indices.Well, often some users working about the crystal growth, have
the habit to work with the hexagonal cell to describe the crystal
setting and are familiar with the hexagonal indices of the most
important crystal directions to be identified. And the conversion of the
indices would be a pain. The new version V3.4 can calculate the
rhomboedral cell parameters from the hexagonal ones in order to do a
faster and more secure orientation, but allow the user to display or to
use the hexagonal indices in stade of the rhomboedral ones to manage the
- An other problem with the V3.3, when the user works with a bitmap
file as input, and wants to output the image with the simulated diagram
as a bmp file. If the output file is opened with Paint, no problem, the
image is OK. But with some image softwres this image appears as
splitted. With the V3.4, the output image file now can be either correct
*.bmp or *.jpg.
- The WinHelp file has been updated.
- Chekcell, Celref, Indx and Poudrix
- Chekcell problem was fixed for the calculation of HKLs on cells with a small alpha angle.
This problem also existed in in Celref, Indx and Poudrix, and have been fixed as well.
- With Chekcell: Bug fixed with problem of display of the predicted peaks when the angular 2-theta
range was set to a very small (negative) value.
