O3'-P (default) 1.60 , i got upto 4.6
could i correct it? on viewing through softwares other than leap those
bonds appear broken. any way to correct it. leap shows warning for 4.6, 3.4
and 3.7 bond distances. there are 2.5, 2.1, 1.5 etc bonds also for this
O3'- P distance but not included in warning.
