Hi Rajan,

  Yes, you would have to measure the center for each frame and use that for the zone coloring.  In order to perform a command or sequence of commands each frame you use the “perframe” command.

Elaine Meng said she tried it and did not get your case to work though, so there may be some unexpected difficulties.  But you should try it.

Hello again, 

Following another old thread, 


I could morph/play the coordinates and Volume at the same time. The script is given below. 

----------------------------------------------------
# Open maps and set threshold
open 1.mrc
open 2.mrc
open  start_full.pdb
open end_full.pdb

vol #0,1 level .025

# Create a marker for coloring
measure center #2 mark true radius 20 color red
~display #4

# Create morph volume
vop morph #0,1 frames 0 model #5

# Create morph models  model #6
morph  start #2 frames 200
morph interpolate #3  frames 200
morph movie

# marker on morph
measure center #6 mark true radius 20 color red

# Color near marker
scolor #5 zone #6 range 50

coordset #6 1,100; vop morph #0,1 start 0 playstep 0.01 frames 100 model #6
----------------------------------------------------


Still the color is at centre of of the first Frame of morph.  If I understand correct I have to measure the centre for each Frame and  add marker and color it. But I still can't make it. Any help/directions in this regard would be very helpful.  

Thanks in advance for your time and help.

best regards
Rajan
