[Chimera-users] Pipes command deletes the previous pipes model

[Elaine Meng]

Hi Vamsee,
Seems like a little bug, probably thinks it’s the same model because they have the same major model number.  However, the workaround is simple… just open the structure twice (in that case, no need to bother splitting), remove the chains you don’t want, and run pipe-and-planks on the different major model numbers.  For example:

open 4g80
open 4g80
del #0:.A-J:.T
del #1:.A-J:.S
focus
color white,r 
pipes #0 helixArrow false helixSplit false helixSplitRatio 7.0 helixEdgeColor blue
pipes #1 helixArrow false helixSplit false helixSplitRatio 7.0 helixEdgeColor red

I hope this helps,
Elaine
