Now I have a Directory C:\Program\context. In the command prompt window I can see a lot of error messages like rsync: change_dir /cygdrive/c/Program/texmf-context/scripts/context/lua failed: No such file or directory (2) rsync: change_dir /current/context/=current (in minimals) failed: No such file or directory (2) I also created a shortcut to a command prompt as described in the wiki. The command prompt opens but context fails to start: C:\Users\Helge\Documents\TeX\contextcontext 'context' is not recognized as an internal or external command, operable program or batch file. C:\Users\Helge\Documents\TeX\context I found in the wiki: It is recommended that you choose a directory that does not have a space in its full path. Ok. This recommendation should be a least a warning. But currently I have some new questions: - How do I uninstall context? - Which directories have been modified by the installer? Where do I have to repair my system?

The pictex output is not convincing, so I hoped the PSTricks output would gave better result. In general it works, but the diagonal bonds are too long. I Hoped that this could be fixed. if we kno wwhere the problem sits it will of course be solved, however as i don't run latex i cannot see what goes wrong Skimming the ppchtex.noc I found that metapost is one possible output driver. I also found a documentation for metapost. But I don't see how I can make PPCHTEX work with metapost in LaTeX. I even don't know if metapost can be used in LaTeX as in ConTeXt. in context mkii metapost support has been integrated for quite some time and in context mkiv it can be processed without noticing so there ppchtex uses even more metapost (which is why there are also some extras) As I (almost) never use LaTeX anymore (and certainly never dvips) I had forgotten about this.

The new ppchtex in mkiv core is an improvement and, as Hans confirms, will not be backported to laTeX. This could be one of many good reasons to switch from LaTeX to ConTeXt! Well I am curious and I would evaluate ConTeXt. I think that http://www.pragma-ade.com/ will be a good starting point to do that. Unfortunately I did not found How to install ConTeXt. Can this be done by adding some packages in MiKTeX 2.8? Probably a silly question... best start with installing the so called minimals (from contextgarden.net) which will give you an independent tree that does not interfere with anything else btw, an easy test is: \starttext \startTEXpage ... some chemical ... \stopTEXpage \stoptext which will give you a graphic that you then can include in a latex doc Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
[NTG-context] PPCHTEX with PSTricks option
The minimal example shows diagonal lines. Since the line output of
pictex is limited, I would choose PSTricks as output driver for better
quality. When I enable the pstricks option, these diagonal lines collide
with the radical atoms. You can easily reproduce this by removing the %
comment symbol.
How can we improve the postscript output. Any hints are appreciated.
Best regards,
Helge Kruse
