I just started using (and liking) ppchtex, and I have a few questions: 1. Is there a way to define a frame offset (there is "fit" and there are dimensions, but an offset would be more convenient)? 2. Is it possible to move the "\bottext" further down? It gets too close to the formula, especially with larger fontsize and smaller formula structures, see example)? \starttext \usemodule[chemic] \startchemical[width=fit,scale=small,size=big] \bottext{α-Glycerophosphate} \chemical[ONE,SB1357,Z0357][\TL{α}{C},\SL{OPO\lohi{3}{2-}},H,H] \chemical[MOV1,SB137,Z037][C,\SL{OH},H] \chemical[MOV1,SB137,Z0137][C,H,\SL{OH},H] \stopchemical \stoptext By the way: X_subscript and X^superscript don't work within \SL{...}. 3. How can I get \ss for *all* the atoms in the formulae and in the bottom text (I tried a few things within \setupchemical)? Thanks, Jörg

[left=,top=] I'll look into your other questions a little later today. Are you using mkii (texexec) or mkiv (context) or LaTeX? Alan

[left=,top=]
This gives absolute values. I would prefer something giving me "fit + <dimension>"
I'll look into your other questions a little later today.
When playing with top, bottom etc again I discovered that increasing the bottom dimension also moves \bottext down. So there only remains question number 3: I would like the atom labels (but not the bodyfont of the document) as \ss -- without including \ss for every single atom.

I am using mkiv (of course!)... Thanks again, Jörg

width=,left=,right=,height=,top=,bottom= (of course, only two of width, left, and right are to be used at a time, as well as two of height, top, and bottom) define the bounding box of the drawing. This is given in units of 4000 per standard bond length. To visualize this, try, \startchemical [frame=on,axis=on,width=4000,height=4000] \chemical [ONE,SB,Z0] [O] \chemical [THREE,B] \chemical [FOUR,B] \chemical [FIVE,B] \chemical [SIX,B,R,RZ] [1,2,3,4,5,6] \chemical [EIGHT,B] \stopchemical For fit+offset, I suggest positioning the chemical drawing inside a \framed[frame=off]{} box using offsets, or some other variant (I particularly like using collectors).

Try "style=sans". We also have "color=" and "rulecolor=".

There are some problems still in mkiv, notably with CARBON, NEWMANSTAGGER, NEWMANECLIPSE, and CHAIR. Hans (and I) intend to work on this but it is not too high of a priority for the moment. Let me know if you have other problems in using ppchtex. Alan
Hi Alan, Thanks for the explanations.

syle=sans works, but not for aligned atoms, e.g. \SL{OH}; a bug? For the time being, I can use \SL{\ss OH}.

I'm sure there will be more questions! I'm using context version 2010.09.05 13.23, have there been any improvements since then? Thanks, Jörg

There are indeed bugs in the use of \SL{} under mkiv. For example, one currently needs to use \SL{\small CH$_2$} rather than \SL{CH_2} as one would expect (use of both \small and explicit math mode). The same is true for any text macro, i.e. \rotate[rotation=+30]{\small N$|$NH}. Hans is on copy as he can probably find the bug rapidly, that is once he can find the time to look into this. Alan
