[Joelib-help] Changed kernel ID + dummy atoms

[Joerg K. W. <we...@in...>]

Hi all,

I've added dummy atom support for MDL-SDF import to CVS.

The hashed kernel ID has changed from
'715333816'
to
'-2141483117'

So please: 'Don't panic'
This will not change your descriptor calculation results, because the 
changes affects only the 'dummy' atoms.

    - joelib/src/joelib/io/MDLSD.java
      Added dummy atom support for 'Du' entries.

    - joelib/src/joelib/data/plain/types.txt
      Internal representation of dummy atoms changed from 'X' to 'Xx'.
      Now we are conform with joelib/src/joelib/data/plain/element.txt

See also:
joelib/kernel.txt for details and detailed ID changes.

FINALLY, you can treat all desriptor calculations with the kernel ID's
'715333816' and '-2141483117'
as equivalent, because nothing relevant has changed in the chemical 
representation.

Kind regards, Joerg
