Hi Vijay,
All "by" operators have a weak priority. This means the following two
expressions are equivalent:
elem S & byring all w. 4 of elem O
elem S & byring (all w. 4 of elem O)
This is a bit unfortunate, I agree that it is not very intuitive. I would
actually expect the highest priority.
Dear Tsjerk and Thomas
For the following small molecule: ClC1[OH+]C(Cl)=CN=C1C(=O)N([NH+]1CCC(SC1)F)CCN
As you advised to use following logic for selecting nitrogen atoms of
rings exclusively.
abc=cmd.select('elem N and byring not elem N')
Likewise, to select Sulphur atoms which are part of rings
Hi Jon,
As far as I see, you're running Open-Souce PyMOL on some unix system. I suggest
you install "idle" on the system, e.g. if this is Ubuntu, install
https://packages.ubuntu.com/xenial/idle-python2.7
Cheers,
Thomas
