[cctbxbb] UB matrix in cbf files

[Keitaro Yamashita]

Dear Carlo,

I reproduced the error message.
However, if I modified the lines in the cbf header,
get_orientation_matrix() returned the correct values.

Here is the modified header lines:

_diffrn_orient_matrix.type  ub_matrix_test
_diffrn_orient_matrix.UB[1][1] 0.083424
_diffrn_orient_matrix.UB[1][2] -0.076007
_diffrn_orient_matrix.UB[1][3] -0.078787
_diffrn_orient_matrix.UB[2][1] -0.103374
_diffrn_orient_matrix.UB[2][2] -0.075939
_diffrn_orient_matrix.UB[2][3] -0.01146
_diffrn_orient_matrix.UB[3][1] -0.034434
_diffrn_orient_matrix.UB[3][2] 0.043832
_diffrn_orient_matrix.UB[3][3] -0.156476


Best regards,
Keitaro
