Refer to Runthrough on Installing the Entire System S Suite on UNIX (Platon/System S, Shelx, Sir, Crunch and Dirdif)

The following screen dumps were taken on a PC Windows X-server. Normally System S/Platon looks much nicer when viewed on a native UNIX screen


The Starting INS File

No need for spacegroup information as System S/Platon will try and work this out. You should only put the molecular formular as System S/Platon will try and work out Z for you.

"s csti.ins nqa" to start System S/Platon running in NQA mode

System S running in NQA Mode


System S/Platon now determining the spacegroup

System S running in NQA Mode


System S/Platon has got the spacegroup, now determining Z

System S running in NQA Mode


System S/Platon Still Determining Z

System S running in NQA Mode


System S/Platon has got Z, it is a heavy atom problem so uses Dirdif to solve and autobuild the structure

System S running in NQA Mode


System S/Platon via Dirdif has solved the structure, has determined there is no need to autobuild and is refining via Shelxl isotropically

System S running in NQA Mode


System S/Platon via Shelxl is now refining anisotropically

System S running in NQA Mode


System S/Platon via Shelxl has refined anisotropically down to 3.5%, and is now optimising the weights via Shelxl

System S running in NQA Mode


System S/Platon still optimising the Shelx weights

System S running in NQA Mode


System S/Platon is now performing automatic structure Validation

System S running in NQA Mode


System S/Platon reports the results of the validation

System S running in NQA Mode


System S/Platon reports the results of the validation

System S running in NQA Mode


System S/Platon suggests that you now may like to look at the struture in ORTEP/ADP mode

System S running in NQA Mode


System S/Platon looking at the structure in ORTEP/ADP mode

System S running in NQA Mode


Now back in System S/Platon mode and can manually play around and investigate the structure
