Dear Richard,

Working with Coot 0.5 revision 1444, I'm seeing strange behavior reading and writing files for Shelx

If I simply read in the shelx .res file, then write a .ins file straight back out, the anisotropic B coefficients are changed.

An example ...

Read in:

RESI 3006  HOH
O 4 .066672 -.410049 .091880 11.00000 .18111 .15204 =
          .15826     .01317    -.06512    -.00049

Written out:

RESI 3006   HOH
O     4  0.066672000  -0.410049000   0.091880000 11.000000000    =
0.219610000 0.114030000 0.158260000 0.011405555 -0.071705000 -0.066259604


This is no simple permutation, and doesn't look correct. Am I missing something obvious here?

No, I am :-/

I'm working in Trigonal Space Group P3221.

That's the issue. I had not checked anisotropic Bs from anything that was not at least orthorhombic. I had not de-orthogonalized the Us.

Thanks, I'll fix this soon and get back to you when it's done.

Paul.
