738	RFE: some way of smoothing molecular surface cusps	Elaine Meng	Tom Goddard	"Sometimes I get cusps on the molecular surface which I assume may be mathematically correct, but don’t look so nice… and I was wondering if you have any ideas of how to avoid them.

In this case (5ego) I don’t have the problem with the DNA surfaces calculated separately for each chain (attached image smooth.png), but when I try to make a single surface enclosing both chains, the sharp points appear (attached image pointy.png).  Changing probe radius and/or grid spacing does not help. I wish for some way to smooth or remove them, even though these cusps may be mathetically correct for the input geometry. 

However, I did the experiment of generating a grid surface in Chimera1 (session attached pointygridsurf.py) and then trying ""sop smooth"" but that method was not very successful. Seems like the rest of the surface gets smoothed more than the points."	enhancement	assigned	minor		Surface								all	ChimeraX
