[Chimera-users] streaks in Chimera image of virus electron density map

[Lu]

Hello,
I've been using Chimera to generate beautiful images of entire virus
particle from an O-style map file. However, most of the images that I
capture have a few black streaks in the image. The streaks appear as thin,
parallel lines, like someone dragged a pen across a painting before it
dried. Does anyone know how I can remove these streaks without having to
resort to Photoshop? I can provide sample images too.
Thanks in advance!
