New Revision: 27100
URL: http://svn.gna.org/viewcvs/relax?rev=27100&view=rev
Log:
Modified some system tests of the structure.align and structure.superimpose
user functions.
The displace_id argument has been introduced for both of these user functions
for finer control over
which atoms are translated and rotated by the algorithm. This allows, for
example, to align
structures based on a set of backbone heavy atoms while the protons and side
chains are displaced by
default. Or if a domain is aligned, then just that domain can be displaced.
