It only takes a minute to sign up. So, I'm looking for unit cell xyz periodic box structure of Pyrope and Grossular. I found some data from several places herehere and here. CIF format files from those databases do not give me proper atomic coordinates of unit cell. This means either CIF of database is wrong, or I am. Or the software is unable to read CIF properly. If anyone knows how to retrieve the unitcell structure of crystals from CIF from those databases, please help me.

CIF contains coordinates for the atoms in asymmetric unit only what Ivan called " the independent part " in the commentsplus the set of symmetry operation to fill the remaining space with those atoms. What you want to do is to open CIF in any viewer supporting that format, make sure the unit cell is packed, e. There are several programs that are capable of doing this.

Unfortunately, I'm not aware of a good method to eliminate atoms located on the periodic boundary with Mercury as packing coordinates can only be changed by a 0.

Possibly Avogadro may deserve a test complementary to the suggestions by andselisk, too. Already the very first automatic display of the data was the one about an unit cell depicted below:. Perhaps equally of interest for you is the entry "Slab builder" in the section of crystallography, where you may define and eventually export little "islets" of the structure of predefined dimension oriented along the Miller indices.

While xyz file is quite easy to construct, I can't guess an easy method to convert them, so it seems more convenient to find structure of compound of interest in more suitable form. The crystal system is monoclinic, which makes the transformation rather painless, nothing that a few lines of awk won't do.

Its also free, and very fast to use if you need to rotate large protein models. It will do most simple angle and distance calculations etc. Basic, but very useful for quick look stuff.

What exactly do you mean by XYZ file? That looks like either space or tab delimited XYZ, do you need comma delimited?

CSV Do you need a header row? What software do you have available? Have you tried using the file as is, by changing the file suffix, because that looks like it has X, Y, and Z values to me. Note that GIS SE is not a tutorial site, and that questions here should demonstrate some basic research and an independent attempt to solve the problem.

This method can be dangerousolder versions of Excel have a limit of rows and Excel does not warn you when you exceed this limitit just dumps the rest of the values; I issue this warning in painful memory of when this limitation bit me when I was least suspecting. The OP clearly states that it is a long file but does not mention if there's more than the Excel limit. If the file is very long opening in Notepad can gobble up memory, take a very long time to open and possibly even blue screen your computer again from painful memory.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

While this version of the script to be referred to as the GULP backend still works great, it has very many dependencies. This backend will give slightly more feedback during the conversion, and will provide a warning if fractional occupancies are found, but the numerical noise is about 1e, compared to 1e for ASE because of the intermediate XYZ file with only 10 digits.

The GULP process will write direct coordinates. PyCifRW 3.

If the structure contains some kind of symmetry, then it can be further represented by including the symmetry information through the corresponding space group which summarizes the symmetry operations that are compatible with the structure i. This way, by specifying the symmetry information, only the information on the atomic sites in the asymmetric unit is sufficient. For a 3-dimensional crystal system, there exist a total of different sets of symmetry operations, named as space groups.

Each of the space groups is uniquely identified with respect to the symmetry operations it contains and the list of these operators can be accessed using the GENPOS tool. Since the above mentioned space groups only act on the atomic positions, they do not have the necessary means to handle magnetic information.

In order to achieve this, the time-reversal operator -1' 0,0,0 is implemented into the non-magnetic space groups also known as crystallographic or Federov space groups to produce a set of magnetic space groups also known as Shubnikov space groups. Depending on the procedure of introducing the time-reversal to the source Federov space group, a magnetic space group can belong to one of the 4 types.

A space group is identified by its unique sequential number. For the crystallographic space groups, this index is a number in the range of [1,]. It contains the space-group, lattice and sites information for the asymmetric unit shell assumed to be given in standard setting one can use our SETSTRU tool to convert to other settings.

As of the moment, the occupational and magnetic information are not supported. Although it has many supported tags for defining additional structural information, unfortunately a consensus on the representation of magnetic information hasn't been reached yet.

Stokes and Branton J. Although one can store all magnetic related information to a mCIF file, its -for the moment- incompatibility with most of the crystallographic software makes it difficult to import the magnetic data contained within. Apart from these file formats, a new structure can be constructed from scratch using the start with a "blank" structure option in the main page of the program.

Once a structure is imported and optionally edited the program can export it in the file formats discussed above. If the space group index is entered as a single number " "then it will be assumed as the Federov space group number magnetic space group of type I and the index will be restored to that of the corresponding in the BNS notation e. If the space group index is given in the OG notation's format ". Although the BNS and OG space group settings for the type I FederovII grayIII translationgleiche magnetic space groups coincide, since for the type IV klassengleiche magnetic space groups they differ, it is highly recommended that the usage of the OG notation in the program should be refrained.

It should be noted that: A change in the space group information updates the symmetry operations information in standard settings from the database.It is available at GitHub.

On the left is a form to be filled in with crystallographic data. On the right is the response area, which will hopefully! This often causes confusion and is discussed here in some detail. Once you are done entering crystal data, click the Compute button. The corresponding feff. To save the contents of the response area, click the Save as button. You will be prompted for the name and location of the save file on your computer.

Note that one- or two-letter symbols are typically used to identify the element at each site. However, full names e. While a feff. Clicking the Save as button will write using the browser's standard mechanism for using or saving files. The Save as button at the bottom of the response area uses javascript to write the contents of the response area to a file on the local machine. The only third-party script used is the ubiquitous jQuery. All other javascript that is executed by the local computer is either embedded in the html file or distributed with WebAtoms and served by the same server that is running WEBATOMS itself.

If saving from the response area is not working, it is possible that you have execution of javascript disabled in your browser. Sites generate one or more common positions and their occupancies sum to more than 1. Lattice constants must be positive numbers and must be written in a way that are obviously interpretable as numbers.

Localization is not respected — the decimal mark is a dot. Note that site coordinates can be negative, but must also be obviously interpretable as numbers using a dot for the decimal mark. Element symbols for the sites must be the standard two-letter symbols as found on any English-language periodic table or Hephaestus. Full names e. Note that site tags can be any string and need not be related to the element symbol, although only the first 10 characters will be used.

Also, tags should not include white space.
