[chimerax-users] Morph map parts transformation in a complex

[HONG ZHAN]

Thank you Elaine for the quick response! I did use the volume resample, but I misunderstood the onGrid pointer… I made it!

The volume morph dissolves one part of the complex and appears the other, but  I want to have a "movement movie", like using morph for atomic models, one part of the complex flies out and fit into the other part, is there any functions I missed?

Thanks!

Hong

Hi Hong,
As mentioned in the volume morph" help,
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#morph>

"the input maps should have the same grids: dimensions, spacing, and numbers of points. Note volume resample can be used to make a copy of one map that has the same grid as another."

Here is the "volume resample" help, with explanation that you can lose some resolution from resampling:

There is also a "volume add" if you are just trying to put different parts together, rather than morphing:

I hope this helps,
Elaine

Dear user group,

I am trying to do volume morph to transform different parts of a complex into another part of the same complex. Because I did drag and fit each segmented parts, the map positions are no longer the same and I have this error: Map positions are not the same.

Is there a way to do the map morph to transform different map parts in the complex?

Many thanks!
Hong
