Hi Siva,
SFCHECK (part of CCP4i) has a very handy option for this. From the
command line:
% mkdir mydir
% sfcheck -f mydata.mtz -po mydir/ -out u -r
% gv mydir/sfcheck_.ps
(or ghostscript/xpsview/whatever postscript viewer you have)
This will generate a number of output files, includin
Well there are no general twinning operators for a monoclinic space
group (e.g. like P3, P4) but there are two special cases which come to mind:
* beta=90 in which case the twinning operator is something like
(h,-k,-l) - pseudo primitive orthorhombic.
* where the monoclinic lattice lengths cons
hello
I have a data set to 2.4 A, which has space group of *P21 *. From the
cumulative intensity distribution graph, indicates that data is
twinned . To run the detwin program in ccp4, one has to know the
twinning operator. Can anybody help me, how can I get the twinning
operator for
