[PyMOL] Query about inserting ligand at preferred base pairs of DNA

[Sneha K. <Sne...@ug...>]

Hello Team,

I need help in inserting ligand to base pair in DNA. I have a drug molecule and want to insert in between the base pairs I am interested in ( it is 12-mer dsDNA). I tried to follow the tutorials but cannot find something where I can insert ligand into the custom DNA sequence I have generated.

I will appreciate if you can please help me or guide me where I can study and understand how to do it.

Thank you,
Sneha

[PyMOL] undefined symbol: H5Pset_fapl_ros3

[amirhossein t. <tag...@gm...>]

Hello,

I am trying to install the pymol with "conda install -c conda-forge -c
schrodinger pymol-bundle".
package is installed without error messages but it fails to start:

I tried the latest libnetcdf "conda install -c conda-forge libnetcdf"
and a clean install but failed again.

Could you please let me know how to solve this?

Best,
Amir

[PyMOL] Align with axis and rewrite coordinates

[Reed, C. (creed) <cr...@br...>]

Is there a way to open a crystal structure and realign the structure with an axis, then save the transformed coordinates?  I want all atoms to remain in the same position with respect to each other...just not with respect to the crystallographically defined x, y, z.  I have tried alter_state command with rebuild....but I only seem to be able to find commands that translate along the x, y, z. The rebuild does rewrite the coordinates, so that bit is working.  I have tried rotating, but this only rotates around an already defined axis.  I need to move the structure away from the predefined axis positions; the easiest way I could think would be to align with a current axis, but open to other ideas. For example, if there is a way to incorporate sine and cosine into the alter_state function...

Thanks in advance!

Re: [PyMOL] intermezzo plugin for analysis of protein-ligand interactions

[Enrico M. <jms...@gm...>]

I have tried to do it in the same way and saw the same errors. I may
think that it does not work with the latest pymol.. May someone
suggest to me some other plugin which could be useful to describe
protein-ligand contacts (electrostatic, vdW etc )?
Many thanks !!

Re: [PyMOL] intermezzo plugin for analysis of protein-ligand interactions

[Saurabh G. <sau...@gm...>]

I was able to install it by downloading the zip file for the web version
link and installing inside pymol for the local file.

However, it shows an error for initialization:

When using Fetch URl mode, it shows charmap error.

[PyMOL] intermezzo plugin for analysis of protein-ligand interactions

[Enrico M. <jms...@gm...>]

Dear Pymol Users!
I am looking for some pymol plugin for the detailed analysis of
protein-ligand interactions. I have already seen:
http://mordred.bioc.cam.ac.uk/intermezzo/
but I could not understand how I could install it ( I am using pymol
2.4 pro installed on my MACBOOK and it seems to me that the package
had been developed for the previous release).

On the site I found:

"Additionally, it will soon also be possible to install the plugin
using the "Install from PyMOLWiki" and "Install from Repository"
sections."

but eventually I could not find it in pymolWIKI.

May you suggest some other solutions which would work with my pymol version ?

Many thanks in advance
Enrico

Re: [PyMOL] CGO object code structure

[Jared S. <jar...@co...>]

Quick follow-up: I just learned from Jarrett Johnson that it is possible to
add alpha to CGO objects on a per-shape basis.  Just prepend `[cgo.ALPHA,
0.5]` (substituting your desired alpha value, of course) before the CONE
(or other) shape.  This alpha value will be used for all subsequent shapes
until you set another `cgo.ALPHA` value by the same method.

Hope that helps.

Cheers,
Jared

Re: [PyMOL] Installing in Linux

[Robert C. <rob...@qu...>]

Hello Peter,

Which Linux distribution are you using?  If you are using one of the Debian-based versions like Ubuntu, then PyMOL is likely available in the distribution's repository.  Then you could use the package management system to install it or simply type in a terminal window:

  sudo apt-get install pymol

Depending on which distribution you are using there may be other steps involved to allow it to find PyMOL.

Cheers,
Rob

[PyMOL] pair_fit crashes Pymol 2.5.2 (incentive, OSX) ?

[James P. (Staff) <J.P...@du...>]

Dear pymol-users

Could anyone confirm that the following test of the pair_fit command causes a crash in the latest Pymol incentive release (2.5.2, 21st August 2021) ?

fetch 1uwh 1z5m
pair_fit 1uwh//A/563-582/CA, 1z5m///193-212/CA

I've found this crashes 2.5.2-incentive on OSX but works fine on 2.5.0-ce (via homebrew).


Thanks in advance !

Re: [PyMOL] CGO object code structure

[Jared S. <jar...@co...>]

Hi Marcelo -

No I don't believe so.  In PyMOL, a CGO `CONE` is a fixed-length list of
floats.  You can see in the cgo.py source
<https://github.com/schrodinger/pymol-open-source/blob/master/modules/pymol/cgo.py#L65>
that
`cgo.CONE` itself is actually a float, too (specifically, 27.0).  My
understanding is that under-the-hood the parser is doing something like:

1. Look at the list of floats passed to `cmd.load_cgo()` and read the first
one as an instruction;
2. Determine how many more values to expect from that instruction (e.g. for
`CONE` it would expect 16 additional floats);
3. Read those values and use them to create the geometry;
4. If there are any values left in the list, treat the next float as a
completely separate instruction, and repeat this process until there are no
values left.

In order to add alpha to a color channel (which I'm not even sure is
compatible with the way PyMOL handles colors—though I'd leave that question
to one of the developers), one would have to add an additional instruction
keyword in cgo.py with a different expected set length of float arguments,
then implement how to translate that instruction into geometry in the
underlying C++.

Of course if that's something you're really interested in doing, you could
certainly take a crack at implementing it in Open Source PyMOL and submit a
pull request.  :)

Hope that helps.

Cheers,
Jared

Re: [PyMOL] CGO object code structure

Thank you Jared,

Yes, I have been using *set cgo_transparency*, but is there a way of
embedding alpha in the CONE object definition? Since I have been using
color1='blue' and color2='red', can I just append an alpha float to the
color lists?

Re: [PyMOL] CGO object code structure

[Jared S. <jar...@co...>]

Hi Marcelo -

Looks like you have the right format for `CONE`.  This should really be in
the Wiki...and apparently is not.  I've just made a couple of pages, others
can of course feel free to elaborate:

https://pymolwiki.org/index.php/CGO_Shapes
https://pymolwiki.org/index.php/Load_CGO

You may also find it useful to look at the Open Source PyMOL source code,
perhaps starting with:
https://github.com/schrodinger/pymol-open-source/blob/master/modules/pymol/cgo.py

Hope that helps.

Cheers,
Jared

[PyMOL] CGO object code structure

[Marcelo D. P. <mar...@gm...>]

Hi all,

I am building a CGO object of a cone and I want to embed a transparency
value to it. So far I managed to create the cone with the line below:

*obj = [cgo.CONE] + begin + end + [radius_begin, radius_end] + color1 +
color2 + [1.0, 1.0]*

Could someone provide more information on how the CGO objects are
structured (which values are expected and their formats)?

Best regards,

[PyMOL] Opening a .pse file causes GUI corruption.

[Mark S. <sa...@um...>]

Dear Developers,

I am running Pymol 2.5.2 on MacOS X 12.2 and have noticed a problem that never existed with 10.14.  I save a .pse file from a recent session.  If I open the .pse by double-clicking it, then PyMOL opens, shows the model, but the GUI (right menu), and scene labels (bottom left) have small, and distorted text.  If I start an empty PyMOL session, and then open the .pse with the File>Open… command, the GUI is intact.  It would be very helpful, if this bug could be addressed and fixed in the next version.

I can screen-shots on request!

Many thanks,
Mark

The problem I described is when running on the MacBook Pro display.  If I connect an external monitor, and open the .pse file by double-clicking, the GUI is not affected.

[PyMOL] missing object control menu for new installation

[Yufeng T. <yuf...@gm...>]

HI there,

I am installing PyMOL on a virtual machine with Windows 10 Enterprise
and tried a few different versions of PyMOL, for all of them I have
the same problem of missing the "Object Control" menu in the GUI.
Attached is a screen copy of the display. I have tried the following:
1. PyMOL 2.5 for Windows Exe Installer from https://pymol.org/2/#download
2. Install Python 3.9 and install the Open Source PyMOL from Gohlke's whl file.
3. Installed Conda and install PyMOL from inside Conda following
pymol.org instruction.

In all three cases, the program can be installed and launched, but all
are missing the "Object Control" menu.

Any hint?

Yufeng

Re: [PyMOL] How to label atom at proper positions?

[sunyeping <sun...@al...>]

Hello professor,
Now I have a new question: how to label the selected CA atoms with strings representing mutations, like "T123D", "K339R", etc?
I tried to use these commands:
  select CAs, resi 123+339
  mut = ["T123D", "K139R", "G223S", "M321S"]
  label CAs, mut.pop
but I found that the labels are put in the wrong positions. So what is the correct way the show the labels for mutations?

Best regards

You can modify the previous script like this,

# ONE LETTER CODES
one_letter ={'VAL':'V', 'ILE':'I', 'LEU':'L', 'GLU':'E', 'GLN':'Q', \
'ASP':'D', 'ASN':'N', 'HIS':'H', 'TRP':'W', 'PHE':'F', 'TYR':'Y',    \
'ARG':'R', 'LYS':'K', 'SER':'S', 'THR':'T', 'MET':'M', 'ALA':'A',    \
'GLY':'G', 'PRO':'P', 'CYS':'C'}

# Select all C-Alpha atoms and set the object name as "CAs"
select CAs, n. CA

# Give Label Them as (Residue Name+Residue Number)
label CAs, "%s%s" % (one_letter[resn],resi)

# Set Label Positions for object "CAs"
set label_position, (3,2,1), CAs

Dear Professor Halil İbrahim Özdemir,

Thank you for your help. The labels shown now are fomatted as "(THR339)", "(SER308)", etc.
I wonder how to show them as single-letter codes plus the numbers without the parentheses, like "T339", "S308".
Thank you again.

Best,

Hi  Sunyeping,

You can easily apply the following script from PyMOL terminal. Have a nice days.

# Select all C-Alpha atoms and set the object name as "CAs"
select CAs, n. CA

# Give Label Them as (Residue Name+Residue Number)
label CAs, "(%s%s)" % (resn, resi)

# Set Label Positions for object "CAs"
set label_position, (3,2,1), CAs

Dear pymol users,

I select a series of CA atoms in a structure in pymol and show them as sphere in pymol and want to label them. If using the label menu at the up-right conner of pymol, the labels shown overlaps with spheres and can not be seen. So I wish to show the labels at a bit distance from the seleccted atoms. Is there a method to do that? I will appreciate to any help! 

Best regards

[PyMOL] visualisations of the hydrogen bonds using preset.ligand_cartoon

[Enrico M. <jms...@gm...>]

Dear Pymol Users!
I wonder to ask regarding the algorithm implemented in pymol for the
calculation of the hydrogen bonds between ligand and protein using
preset.ligand_cartoon demonstrating the interactions?
I've just compared predicted hydrogen bonds for the same complex that
I could observe with Chim*ra and found that there were differences:
pymol tends to predict more hydrogen bonds considering additional
interactions located on the longer distances. Are there some built-in
commands in pymol that would allow me to modulate geometrical criteria
(cut-offs?) for the hydrogen bonds search assuming that I am operating
with multi-model pdb (results of docking) using command:
preset.ligand_cartoon('my_pdb*',_self=cmd)
Many thanks in advance
Cheers
Enrico
