Re: [Jmol-users] Unit cell, axes bug/feature?

Yes, it is intentional. There was an exception being made for biopolymers, but I removed that with the idea that it was inconsistent with all other crystal file loading, where the unit cells is shown. The premise is "If you are asking for a unit cell, you probably want to see it." As you say, it i

[Jmol-users] Unit cell, axes bug/feature?

2016-05-24 Thread Eric Martz
Dear Bob, In JSmol December 23 2015 (and earlier) the following commands do NOT display the unit cell nor axes: load "" {555 555 1} range -7.0; load "" {1 1 1}; In JSmol May 17, 2016 these commands display the unit cell and axes. Is this an intentional change? Its easy enough to turn the uni

2010-07-22 Thread Robert Hanson
OK, a question for the crystallography subgroup: Nick Greeves has pointed out that some of the unit cell functions have recently changed (probably when I added generalized data graphing) Here is the situation: prior to Jmol 11.8.[what?] unitcell {0.5 0.5 0.5} just moved the cell and axes. Only

Bob, Jmol version 11.1.41 has repaired my problems with atoms at special positions. It took a little playing around with "hide" and "display" to get all the bonds drawn corectly, but (so far) all of my cells with special positions work correctly! See, e.g., http://ma

10.9.54 adds the capability to use space group information with Cartesian coordinate files. Right now, just PDB, but there is no longer any reason it couldn't also be done with XYZ files and, perhaps, a data statement. So Glenn, if you can write those files in PDB format, you can do what you w

Jmol currently only supports periodicity in the context of a unit cell. In order to replicate, you need: 1) a file format that supports defining the unit cell (CIF, RES) 2) to define all atom positions in fractional coordinates 3) to define the unit cell parameters 4) to provide a space group nam

Hi, I have calculated structures in the form of xyz files, and would like to repeat them periodically, I if have found a menu in jmol which allows you to draw a unit cell but can't find where to specify the dimension of the unit cell or the repeat periodicty in the x y or z direction . Is ther

Hi, I am trying to read a pdb structure which has an atom as being at 0, 0, 0 but when I read in the file the atom does not appear to load, and when I use the crystal builder and input the cell parameters, still the atom/atoms appear. The real structure that I am looking for has an atom at eca
