Re: [phenixbb] phenix.twin_map_utils gives AttributeError: 'module' object has no attribute 'r_free_flags_params'

run xtriage, it will compute numbers for you and give twin laws. P p.s. 2.0 indicates no twinning, or twinning with a load of other problems ;-) 2008/5/21 Francis E Reyes :

Thanks Peter

I was hoping for testing for perfect merohedral twins. I tried the Yeats server http://nihserver.mbi.ucla.edu/Twinning/ and my / <I>^2 statistics > 2.0 (max is 2.1) . Is that interpreted as untwinned then?

Thanks

Try donwloading CCI_APPS. This should be fixed in that release.

(your cell and sg has no twin laws though, so you will just get a normal map out of it)

Any ideas?
