[Chimera-users] morph map and movie recording

[Elaine Meng]

Hi Moumita,
Maybe the sequential fitting option of command "fitmap" will do what you want:

<http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html>
<http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html#sequence>

There is a video tutorial, 
<http://www.cgl.ucsf.edu/chimera/videodoc/FitSeq/>

...but it might be slightly confusing because it shows non-sequential fitting first.  Only the second half of the video shows the sequential fitting command.  Also, it shows fitting multiple atomic structures into a larger map, but the command actually creates a map from each structure and then fits the maps into the larger map (i.e. you don't need the atomic structures).  However, you do have to put the smaller maps in approximately the right place before using the command.  Although "fitmap" also has a global search option, it cannot be combined in the same command with sequential fitting.

I hope this helps,
Elaine

However, the "vop morph" command is all-in-one and creates the map right before playing it, so there is no opportunity to change the new map's settings and hide its dust in between.  Unfortunately I don't know how to solve that problem.  In other words, I don't know how to separate creation of the morph map and playback of the morph in a command script, so that you could control its threshold and dust display with other commands in between.  I'm hoping our expert will be able to suggest something when he returns.

By default the "vop morph" command should hide the input maps (hideOriginalMaps true).

I am following the mini-video animation example script of vop morph using the recommended chimera 1.7 version 2013. The script actually recorded the movie but in the movie threshold changed from what I set and it turned some maps to x 90 degree not all and it is not showing the morph animation only the superimposed maps. Another problem is though I remove the dust after loading the maps but it came back in the morph and in the movie as well.
