<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">Hi Kenji,<div class="">The shape of pocket will be different in different proteins so you can never get it to look exactly the same as some other example. Making figures is always a long trial and error for each different protein with lots of hand rotation and other interactive movements, it is not something that is solved by some expert command that I could give you. However, you can sometimes make an image similar to other images you have seen.</div><div class=""><br class=""></div><div class="">Your first image in your original message</div><div class=""> <img apple-inline="yes" id="BBE84254-E5E2-4F13-95CC-9F0EF25AB3D3" src="cid:D577671A-3312-4A1E-9C76-71C9AAACC31F@gateway.sonic.net" class=""></div><div class=""><br class=""></div><div class="">...already looks similar to the second one to me</div><div class=""> <img apple-inline="yes" id="ADF94BF7-D2C6-432D-9296-229582828C78" src="cid:C347AB2D-F866-4A4A-845A-C6AA4CDAE08B@gateway.sonic.net" class=""></div><div class="">... it is just that the shape of the pocket is different -- you just have to experiment with the position of the clipping plane and the rotation of the structure to show it as best as possible. The front/back clipping can also be adjusted in the Side View tool (menu: Favorites... Side View).</div><div class=""><br class=""></div><div class="">If you mean that you want the dark gray color instead of the light orange, you can change that cap color using the Surface Capping tool (menu Tools... Depiction... Surface Capping), turn on "Use cap color" and then click the square color area and use the color chooser to change the color.</div><div class=""><br class=""></div><div class="">Another kind of clipping allows clipping only the surface but not clipping the ligand.

It requires some practice using it and can take a lot of time moving everything around to make it look good. Again, you might not need to use this, if you can use the simple front/back clipping that you already tried.</div><div class=""><br class=""></div><div class="">Elaine</div><div class=""><div class="">-----<br class="">Elaine C.

There is no simple solution, you just have to try showing and hiding different parts of the surface. Sometimes you can rotate the structure so that the clipping (where the front is sliced off) is at a better position to show the pocket. Even if you turn off clipping, sometimes it is possible to hide the outer surface and show only the pocket, but it depends on the shape of the surface. <br class=""><br class="">There is an example in the Structure Analysis and Comparison tutorial, in the "Surfaces and Attributes" section, of showing only the pocket surface around the ligand:<br class=""><https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/squalene.html><br class=""><https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/squalene.html#surfaces><br class=""><br class="">That example uses "sop zone" to show only the surface of receptor atoms within 5 angstroms of ligand; you could use some other distance if it looks better in your structure.. Again, however, whether that looks good enough depends on the shape of the surface and the pocket.<br class=""><br class="">If you want to turn off the front/back clipping, you can use command "clip off". Another thing you can try (but that would also take time to experiment) is Per-Model Clipping tool, where you can turn on a clipping plane, but then rotate it by hand to any angle. You can make the clipping plane only affect the surface and not the atoms.<br class=""><https://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/per-model/per-model.html><br class=""><br class="">I hope this helps,<br class="">Elaine<br class="">-----<br class="">Elaine C.
