9.3 PLATON - ANALYSE Menu <strong>WinGX</strong> <strong>v1.64</strong><br />
2. Problems are indicated when:<br />
• Convergence is unstable<br />
• A large number of reflections left out during the iteration process (This may be well<br />
indicative for problems with the data, and should be checked for).<br />
3. A report on the use of SQUEEZE should always state for each (significant) independent<br />
void:<br />
• Where the void is (i.e. x,y,z)<br />
• Its volume<br />
• The number of electrons recovered.<br />
12 PLATON in the <strong>WinGX</strong> implementation<br />
The version of PLATON in <strong>WinGX</strong> is virtually identical to the UNIX workstation version,<br />
except that System S is not available (it is too UNIX specific). The major differences concern<br />
the input and output files. To maintain the normal <strong>WinGX</strong> file naming protocols, the ASCII<br />
listing file is renamed as PLATON.LST while the input files are generally created<br />
automatically. In normal operation, a temporary file called name.SPF is created by reading, in<br />
the following order, the SHELXL.LST (to try and obtain errors on the coordinates), the<br />
name.RES file or the name.INS file. If there is some problem with any/either of these files,<br />
the program may abort. The first thing to check is whether the SHELXL.LST file is from a<br />
refinement which has terminated normally - if not delete this file. The output name.HKP files<br />
are also usually renamed depending on the operation carried out The program is ALWAYS<br />
run in locked mode because of this renaming procedures. The hypertext help functions<br />
exactly as in the UNIX version. .<br />
