[PyMOL] extra bonds

2013-04-29 Thread Jianghai Zhu
Hi,

In my trajectory movie, there are some minor distortions of some of the 
residues, but the sticks presentation in pymol seems fine.  However, after I 
loaded the trajectory pdb file use discrete=1, extra bonds would be shown in 
sticks in those slightly distorted residues.  Is there is way to avoid those 
extra bonds?  Thanks a lot.

[PyMOL] SS in a trajectory

2013-04-24 Thread Jianghai Zhu
Hi,

I have a trajectory file, in which two short helices would merge into one long 
helix.  However, when I play the trajectory in Pymol as cartoon, the long helix 
would still be shown as two helices with a loop in between.  Is there a way to 
force Pymol to show a long helix for a specific range of frames in a 
trajectory? Thanks a lot.

In MacPymol, I can save a movie as a quicktime movie by "File->Save Movie

[PyMOL] movie for morphing

2013-04-05 Thread Jianghai Zhu
Hi,

I have a pdb containing the morphing.  I can play the movie with the loaded pdb 
file.  Now I want to start the movie with rocking the first state for a few 
seconds and end the movie with rocking the last state for a few seconds.  How 
do I do that?  Can I rock or nutate a state in the middle for a few seconds as 
well?

Thanks.

[PyMOL] refinement in morph

Hi,

If I turn on the refinement option in morph, the non-covalently bonded atoms 
like metals and waters are moving around a lot.  However, if I turn off the 
refinement, there are some distortions in my protein.  Is there a way to make 
the non-covalently bonded atoms just move along the transition path?

Re: [PyMOL] eMovie question

Simon,

Thanks for the suggestion.  That is exactly my workaround.  But I  
found out that I don't have to render the first 70 frames.  I used  
"mpng xxx, 70, 300" and it worked fine.  So this should save some  
rendering time.

I am trying to make a simple movie using eMovie. I rotate the molecule

[PyMOL] question about SUPER

2008-06-05 Thread Jianghai Zhu

Hi,

I am using SUPER to superimpose different structures in PyMOL.  And I  
noticed that when I try to superimpose a lot of different structures  
onto one reference structure, the number of aligned atoms is getting  
smaller and smaller as I keep using SUPER command.  And eventually  
structures cannot be aligned anymore even though the first few  
structures are aligned quite well.  So is this a bug?

Hi, all,

I am trying to render my picture in a perspective view in pymol 0.98.  
Is there a way to make the perspective effect more dramatic than the 
default way?  I mean to make the far end smaller and the close end 
bigger.


Thanks.

[PyMOL] density around ligand

Hi, all,

Is there a way in Pymol to draw electron density only around my ligand?

Thanks.

[PyMOL] question about "side chain helper"

2005-02-11 Thread Jianghai Zhu

Hi, all

I am trying to make a picture in pymol. I have my protein in cartoon 
presentation and some residues in stick presentation. When I turn on 
"side chain helper", it works beautifully except that my glycines 
disappeared. Is there any way to get the glycines back?


Thanks.

[PyMOL] a minor bug in MacPymol 0.98 beta 27

2005-02-10 Thread Jianghai Zhu

Hi,

I found out that once in a while macpymol lost memories of previous 
commands. so the "up" key could not bring the previous commands back in 
the external window. I don't know if this only happened to me. It could 
be a minor bug.

Re: [PyMOL] macpymol beta bug

2004-12-04 Thread Jianghai Zhu
Thanks. The new beta is very good. Especially like the 
side_chain_helper. Now I just wonder how I can get APBS plugin work 
under MacPymol.

Hmm...

The problems are fixed in MacPyMOL beta24 (http://delsci.com/macbeta).

Also note that there is a new setting "cartoon_side_chain_helper" that
greatly simplifies figure preparation when you mix cartoons and side 
chains.
It takes care of making sure the cartoon goes through the CA position, 
and
it automatically hides main chain atoms when the cartoon 
representation is

visible for a residue.

You can activate it under the Display/Cartoon menu, or with "set
cartoon_side_chain_helper"

[PyMOL] macpymol beta bug

2004-12-03 Thread Jianghai Zhu

Hi, all,

I am using the MacPymol 0.98beta23. I found in the menu "Setting --> 
Cartoon" or "Setting --> Transparency" or "Setting --> Rendering" all 
the submenus are grey and I can't select them. What command should I 
use to do, for example, "use most memory in rendering"?

[PyMOL] unit cell

2004-08-15 Thread Jianghai Zhu

Hi, folks,

In pymol, how do you draw a unit cell? The cell constants are in the 
pdb file and the manual says pymol can display unit cell. I just could 
not figure out how to do it.


Thanks.

The best way to overcome this is to compile it, so that you don't have

 Fink doesn't build the g77 dynamic library, which allows you to avoid 
this problem.


If you use g77 3.4.1 (which is what is currently in fink) with gcc 3.3 
you will have some linking errors.


I could not get the LDFLAG to let me do this (i.e., I coudn't figure 
out how to do this the "right way"), so I instead did the following:


1.  start up zsh  (to make use of its recursive globbing capability)

2.  configure

3.  perl -pi -e 's|\-L/usr/local/|\-lcc_dynamic \-L/usr/local/|g' 
**/Makefile


make; make install






Re: [PyMOL] A couple of quick PyMOL + APBS notes

2004-07-15 Thread Jianghai Zhu
The reason it doesn't work is because, I think,  APBS was not compiled 
by the fink g77. More likely it was compiled by a g77 from 
http://hpc.sourceforge.net/ or other similar places. So you need to 
install that version of g77 to get APBS running on you mac. If anybody 
can compiled APBS using fink g77, that will be great.

Re: [PyMOL] Powermate dial with Pymol on OS X

This works, but it could ruin my sessions which are very important for 
us.


Warren, is it possible to add the support of powermate into PyMol or 
MacPyMol? Since it works perfectly with O, I think it could be a very 
helpful control tool for PyMol too.

That is exactly what I needed.  I guess I need to RTFM some more...

So for anyone else who might be interested, here is how to get the 
Powermate dial to play nice with
Pymol (I did this on OS X but I assume it would be very similar on 
Windows).

Use the command set_key from PyMOL (API only)
one of the examples on 'help set_key' is precicelly
what you want.

Re: [PyMOL] protein surface

2003-02-25 Thread Jianghai Zhu
Hi, kaushik, 

Thanks for the response. Those metheds sound good first, but 
when I think about it,  they are not real accessible surfaces  
because these surfaces still show those small reentrant shapes 
between two consecutive atoms. Is there anyway to get around 
this? Or can I read any surface file ouput by other programs in 
pymol?

Thanks

[PyMOL] protein surface

2003-02-24 Thread Jianghai Zhu
Hi, 

When I used "show surface, protein", what kind of surface did I 
generate? Molecualr surface, accessible surface (what is the 
probe radius?)? How can I define the type of surface I want and 
the probe radius? Besides generating the surface by itself, 
could pymol read other surface files? like msms format, grasp 
format, etc.

Thanks.

I have a pdb file only contains CA atoms. When I try to show

only show nb_sphere on the screen, is there a way to show

structures have been already defined in the pdb header.
