Hi, The default baond length of 2.0 is not in a datablock, but in the file all.dat (the connectivity file), on the first line : LINK 2.0 This says that for all atoms not define in this dictionnary, there will be a bond if the atoms are less than 2 A apart. If you increase this, be sure that this dictionnary contains most of the residue you want to display, otherwise you might have lots of unwanted bonds... It is probably better to add an entry in this dictionnary for your modified residue (syntax of this file is quite easy). hope this helps laurent ---------------------------------------------------------------------- Laurent Maveyraud maveyrau@bio5.chemie.uni-freiburg.de Institut fuer Organische Chemie und Biochemie Albert-Ludwigs-Universitaet phone: (49) 0761-203-6090 Albertstrasse 21, fax: (49) 0761-203-6161 D-79104 Freiburg http://bio5.chemie.uni-freiburg.de/~maveyrau ---------------------------------------------------------------------- On Sat, 15 Nov 1997, Minakshi Ghosh wrote: > Hello 'o'ers, > I am trying to draw bonds where the bond length exceeds 2A, ie C-Br/C-I > etc. It seems that there is a default limit to the bond distance in O .. > does anybody know which data-block contains that information. > Many thanks, > Minakshi > > ======================================================================== > Minakshi Ghosh > Laboratory of Molecular Biophysics Tel: +44 1865 275392 > South Parks Road Fax: +44 1865 275182 > Oxford OX1 3QU E-mail: mina@biop.ox.ac.uk > > > > >
