These two transformations are themselves related by a twofold rotation, which is a true symmetry of this crystal structure. There is therefore only one ambiguity transformation. The transformation is strange because it isn't one of the symmetries displayed by a monoclinic lattice in general. This ambiguity has arisen because of of the particular unit cell parameters for this structure. diff --git a/doc/man/crystfel.7 b/doc/man/crystfel.7 index f56fa22d..2aad48c5 100644 --- a/doc/man/crystfel.7 +++ b/doc/man/crystfel.7 @@ -45,6 +45,9 @@ A tool for resolving indexing ambiguities. .IP \fBget_hkl\fR A tool for manipulating reflection lists, such as performing symmetry expansion. +.IP \fBcell_tool\fR +A tool for manipulating unit cell files, such as applying transformations. + .IP \fBcell_explorer\fR A tool for examining the distributions of unit cell parameters. @@ -167,6 +170,7 @@ You should have received a copy of the GNU General Public License along with Cry .BR render_hkl (1), .BR hdfsee (1), .BR get_hkl (1), +.BR cell_tool (1), .BR geoptimiser (1), .BR whirligig (1), .BR list_events (1), diff --git a/doc/man/geoptimiser.1 b/doc/man/geoptimiser.1 index a176de6b..3c25b7b3 100644 --- a/doc/man/geoptimiser.1 +++ b/doc/man/geoptimiser.1 @@ -27,10 +27,7 @@ For a complete description of the optimization algorithm, see the following pape O.
