Cartoon edges messed up the rendering in segments.

[javierbq]

Hi Marco,

I am trying to set the color of a protein segment to red by breaking the structure into 3 segments that are then added to the viewer. Everything seems to work fine expect when the structure is rendered in cartoon mode, the edges of the segment are all messed up.

Any suggestion on how I can fix this?

Thanks! Javier

Hi Javier,

that doesn't look great :(. There are other ways to achieve what you want. To recolor a part of a structure, you can also just specify subset of atoms you want to color to colorBy:

If you want to use it for highlighting, you can also use setSelection():

Here is a sample of this in action:

Hi Marco,

Your solution works well for coloring. Is it posible to do something like this for style?

I am trying to change the style of only a section of the protein by rendering the protein as 3 different structures and I get the same problem with the cartoon visualization that I was having before.

Is there any good way of doing this?

Ah, I see. That's something I haven't been optimizing and checking for too much. I'll have to take a look what can be done about that. It's certainly not going to be a quick fix, though.

I've fixed part of the issue in one of the latest commits. At least the twist at the beginning is gone.

Thanks Marco, it's looking much better!
