[chimerax-users] Distinguishing between upper and lower case chain IDs before and after splitting chains

Hi,

My model (cif format) contains 34 chains, and so I've been using upper case
and lower case letters for chain IDs. When I read in my model, the select
command distinguishes between upper case and lower case, but after applying
the split command on my model ('split #1 chains'), the select command no
longer distinguishes between upper and lower case. I.e. 'select #1/D' will
select both chains D and d. The split command works correctly, producing
models 1.1-1.34.

Also, is it possible to create a model from a selection? I can't find such
a command anywhere, and the only thing I can figure out is to do the
following:

'save *name* format mmcif models *selecion_name*; open test.cif'

Thanks,

Yazan
