    The XYZ file format is a chemical file format. There is no formal standard and several variations exist, but a typical XYZ format specifies the molecule geometry by giving the number of atoms with Cartesian coordinates that will be read on the first line, a comment on the second, and the lines of atomic coordinates in the following lines.

    The wwPDB maintained the specifications of the PDB file format and its XML alternative, PDBML. There was a fairly major change in PDB format specification (to version 3.0) in August 2007, and a remediation of many file problems in the existing database. [3] The typical file extension for a PDB file was .pdb, although some older files used .ent ...

    The triangle would be used for many regular set square operations, the rulers likewise would function as rulers, but the unique function was the 3:1 reduction ratio between measured distance and drawn line. [2] [3]: 210–214 A line is drawn along the beveled edge (the side of middle-length) of the triangle.

    SDF is one of a family of chemical-data file formats developed by MDL; it is intended especially for structural information. "SDF" stands for structure-data format, and SDF files actually wrap the molfile (MDL Molfile) format. Multiple records are delimited by lines consisting of four dollar signs ($$$$). A key feature of this format is its ...
