CHT(1) User commands CHT(1)
NAME
cht - chemtool drawings analyzer
SYNOPSIS
cht [options] filename.cht
DESCRIPTION
cht is a commandline tool to derive the sum formula and molecular mass of the molecule depicted in a chemtool drawing file. It is also
available from within chemtool to calculate these data for the current structure or a marked fragment of it.
cht currently recognizes the element symbols C, H, O, N, P, S, Si, B, Br, Cl, F, I, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga,
Ge, In, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Sb, Sc, Se, Sn, Sr, Te, Ti, Tl, V, Zn (that is, all main group elements except the noble gases, and
the first row of transition metals) and the abbreviations Ac, Ade, Bn, Bu, iBu, tBu, Bz, BOC, Cyt, CE, DBAM, DMAM, DMTr, Et, Gua, Me, Ms,
MOC, MOM, MMTr, Ph, Pr, iPr, Tf, Thy, Tol, Tr, Ts, TBDMS, TBDPS, TMS, TMTr, Ura, Z.
It can handle two levels of parentheses; e.g. P[OCH(CH_3)_2]_3.
When cht detects any duplicate (overlapping) bonds in the drawing file, it will prepend an exclamation mark to the calculated (and likely
wrong) sum formula.
OPTIONS
cht understands the following options:
-h, --help
Displays brief help and list of options.
-e, --exact
Calculate exact mass for MS.
-v, --verbose
Be verbose.
-d, --debug
Be extremely verbose.
BUGS
cht can misinterpret molecules that contain the 'aromatic ring' symbol, as it uses a fixed search radius to identify the aromatic system
that it denotes. It also does not handle the 'partial double bond', so you should avoid these two in drawings that you intend to use with
cht.
A label that is offset from the corresponding bond end by more than five pixels is not recognized, so that the default CH2 or CH3 group
enters the calculation in its place.
In general, one should check the plausibility of the generated sum formula wherever possible.
