[Chimera-users] Creating a smooth disk

Hi Henrique,
I can only reproduce this problem if I make the window size rather small, like 600 pixels wide.  If I make the window bigger, the extra lines go away.  Also, I can only see it on the screen; even keeping the small Chimera window, when I save an image of the same size but with supersampling (which is the default) there are no extra lines on the saved image. So I can only say to try one or more of the following:

(1) don’t screenshot, use save image with supersampling (which initially saves a bigger image and then shrinks it to the final size); try supersampling at least 2x2, could also try 3x3… this is a setting in “Image Options” in the dialog from menu: File… Save Image

(2) try bigger Chimera window

(3) try saving bigger image  (larger numbers for “Image width” and “Image height”) 

I hope this helps,

Here I attached screenshot showing lines and then image about the same size but saved with with 2x2 supersampling.
