[PyMOL] Question on geometry option in replace command

[Lei Q. <lei...@ou...>]

Dear users,
Could I ask a question on geometry option in replace command?
I tried to use Build/Fragment/XXX to replace an atom to a new one, and pymol GUI shows the corresponding replace command.
However, I found the geometry option always equals to 4.
For example,
PyMOL>replace O, 4, 2
PyMOL>replace N, 4, 3
PyMOL>replace C, 4, 4
I tried to replace the atom in different types of bonds: single/double/triple bonds, but the geometry value is always 4.
Could you please help me figure it out? Thank you very much!
Best,
Lei

[PyMOL] Announcement: The 17th CCP4/APS Crystallographic School, June 23rd-30th, 2025, APS

[Xu, Q. <qx...@an...>]

Dear Colleagues,

We are pleased to announce that the 17th annual CCP4/APS Crystallographic School, "From Data Collection to Structure Refinement and Beyond," will be held from June 23rd to 30th, 2025, at the Advanced Photon Source (APS), Argonne National Laboratory (ANL), near Chicago, Illinois, USA. All details can be found on the school website: http://www.ccp4.ac.uk/schools/APS-2025/index.php.

Dates: June 23rd through 30th, 2025 (on-site), June 2nd and 16th (virtual)
Location: Advanced Photon Source, Argonne National Laboratory, Argonne (near
Chicago), Illinois, USA

The school comprises two parts: a data collection workshop and a crystallographic computing workshop. The data collection workshop includes beamline training, data collection at GM/CA@APS beamlines, and data processing, using only the participants' crystals. The crystallographic computation workshop will feature many modern crystallographic software packages (including CCP4, PHENIX, XDS, HKL, and DIALS) taught by authors and other experts. This workshop will also introduce elements of CryoEM, such as model building and refinement. The daily schedule will be organized in three sections – lectures, tutorials, and hands-on (interactive troubleshooting of the technical difficulties participants face in their projects). Two additional virtual days (June 2nd and 16th, 2025) will cover sample preparation (cryo-cooling), bioinformatics, and introductory crystallography lectures. We have had considerable success resolving these problems in past years, as attested by resulting publications (see http://www.ccp4.ac.uk/schools/APS-school/publications.php). A draft program can be found on the School website.


Applicants: The workshop strongly encourages students who need expert help with difficulties/challenges in their own projects. Graduate students, postdoctoral researchers, and early-career faculty, along with commercial/industrial researchers, are encouraged to apply. Only about 20 applicants will be selected for participation.

Application: The application deadline is May 15th, 2025, we strongly encourage interested participants to apply as soon as possible. To apply, visit https://www.ccp4.ac.uk/schools/APS-2025/application.php

Fees: There is a $500 participation fee for selected academic students and $1,500 for industrial researchers. No credit card will be required for registration; students who are selected to participate will be contacted to pay. The students will be responsible for their transportation and lodging. The workshop organizers can assist in making lodging reservations at the Argonne Guest House. The workshop will cover all other expenses (including meals).

We hope to see you at the school.

[PyMOL] How to iterate over a distance object?

[Csongor M. <cso...@ub...>]

I am trying to iterate over lots of distances that I can generate with cmd.distance(name = 'distA_B', selection1 = 'selA', selection2 = 'selB', cutoff = 3.6, mode = 2) for example. My only problem is that I don't know how to iterate over them. How can one iterate over objects that are not selection of atoms?
(I'm doing this from python using the pymol-bundle, but even in pymol I can't find a way to save these into a file or print them or save them in a variable somehow)

Kind regards,
Csongor

Re: [PyMOL] Anaconda python-bundle package documentation or help

[Norbert S. <st...@bb...>]

Dear Csongor,


as far as I know it is not well documented how you can access the python 
objects and its methods or data structures created by the PyMOL API. For 
many tasks one usually finds some information, often PyMOL or python 
scripts. Concerning your example of the hydrogen bonds determined by the 
distance command, the following python script may provide hints:


https://pymolwiki.org/index.php/Get_raw_distances

and: 
https://pymol-users.narkive.com/zHPUseVG/pymol-is-there-a-way-to-count-hydrogen-bond-interactions

When working with the PyMOL distance command to determine hydrogen bonds 
please note that the algorithm is very generous concerning non-linearity 
of the D-H...A angles if you use the default parameters. In addition, it 
will miss some perfect hydrogen bonds.

See
https://research.uni-leipzig.de/straeter/pymol/pymol_hbond.html
and
https://github.com/schrodinger/pymol-open-source/pull/374

Best wishes,

Norbert

Re: [PyMOL] Anaconda python-bundle package documentation or help

[Tamas H. <bio...@gm...>]

Dear Csongor,
cmd select creates a named selection. if you do not use a name, the 
default name "sele" will be used. You see this if you use the gui 
version. Plus: https://pymol.org/dokuwiki/doku.php?id=api:cmd:select 
cmd.select("resi 150-160")

cmd.color("red", "sele")

cmd.select("myselection", "resi 150-160")

cmd.color("red", "myselection")

Bests,

Tamas

[Csongor M. <cso...@ub...>]

Hey everyone,

I am trying to use pymol from python to have some repetitive tasks done. I've managed to get some basic functions running but I'm running into walls frequently. I couldn't find a tutorial or documentation about this. Am I missing something? I know it's under development but I would assume that some basic instructions would be available somewhere, otherwise the conda package isn't very useful.

I've managed to sort out the cmd.select() function for example but I can't use the data, there is no object or output. All I can do is to cmd.save() selection into a .pdb file. I've managed to select ligand, and then residues around it, I've also been able to use show_contacts() (from link below) between two selections, but I can't access the pairs that suggest hydrogen bonding, it is only a visual thing. Even from pymol, the software, if I do it manually, I don't know how to save those (unless I save it as a pymol session file that is not human readable).

[PyMOL] Question Regarding Timeline Python API Availability in Open-Source PyMOL

[Martin U. <mar...@st...>]

Dear PyMOL Community,

I am exploring the Timeline Python API as described on the PyMOL Wiki 
(TimelinePythonAPI 
<https://pymolwiki.org/index.php/Timeline_Python_API>). However, when I 
attempt to use |timeline_add_composition()|, I encounter the following 
error:

/AttributeError: module 'pymol.cmd' has no attribute 
'timeline_add_composition'/

To investigate further, I tried both the prebuilt wheel file 
|pymol-3.1.0a0-cp311-cp311-win_amd64.whl| from the GitHub repository 
(pymol-open-source-wheels 
<https://github.com/cgohlke/pymol-open-source-wheels>) and a build from 
source using the commit |PYMOL-4365: Filter gizmo and selections from 
thumbnails and exports|. Unfortunately, both approaches resulted in the 
same error.

Could someone clarify whether this API is available in the open-source 
version of PyMOL or if it is part of the incentive version?

Thank you for your time and assistance.

Hello,

Under the plugin menu option there is an included default plugin "alignment" tool which will bring up an alignment GUI.

Hello,
I was wondering if there is GUI feature for loading and superimposing 2 proteins. I would like to use pymol for students that do not have any experience using commands.

Thanks,

I usually open the second molecule after pymol has loaded first molecule by
just dropping the file on the window.
Afterwards I used align Command: https://pymolwiki.org/index.php/Align
Super command is also useful: https://pymolwiki.org/index.php/Super

Also after loading 2 molecules you can use Align menu under plugin:

It has multiple algorithm for alignments.

Re: [PyMOL] Running pymol without launching window in batch

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

Apart from others' reply, I believe pymol will run .pml files while python
will run .py files.

[PyMOL] 2 Molecules superposition

Re: [PyMOL] Running pymol without launching window in batch

[Gruber, K. (<kar...@un...>]

Dear Yarrow,

The problem in your script is the `if __name__ == "__main__"` clause.

When the script is run using `pymol -cqk test.py`, __name__ refers to the string "pymol".

The following script fetches a structure from the PDB and saves a PNG image. Run it using `pymol -cqk test.py -- <PDB-ID>`. (The flag -k prevents loading pymolrc and plugins.)

```python
from pymol import cmd


def main(pdb_id: str) -> None:
    print(f"Loading PDB-ID {pdb_id.upper()}")
    cmd.fetch(pdb_id)
    png_file_name = f"{pdb_id}.png"
    print(f"Writting image to {png_file_name}")
    cmd.png(png_file_name)


if __name__ == "pymol":
    import sys

    pdb_id = sys.argv[1]
    main(pdb_id)
```

Best regards,

Karl

Hello,

It is much easier than that.

Make a pymol script, for example, test.pml:

#
load 3gbn.pdb
select Selection1, resi 80:115
save Selection1.cif, Selection1
quit
#

then run it with the -c option :
pymol test.pml -c

If you want to pass an argument, like the filename of a pdb file to be directly opened, then use the -cp option.

Re: [PyMOL] Problem launching PyMOL from macOS 13.7.1

[Thomas S. <tho...@sc...>]

Hello Dr. Saper,

This does appear to be a bug and I was able to reproduce the same behavior
on my Mac. Opening the same pdb repeatedly in the same window should result
in states being added, but there's no reason why PyMOL should be doing this
when double clicking on files. It seems like PyMOL is loading the
structure twice for some reason but this pattern doesn't repeat if you
continue to open the same file.

I will create a ticket to investigate further and hopefully have a fix for
this in the near future. In the meantime, you can delete the second state
using "delete_states {your object name}, 2", though I recognize this is
annoying to type each time and is not a long term solution.

Thanks for reporting this,
Thomas Stewart

[PyMOL] Problem launching PyMOL from macOS 13.7.1

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

I am running the latest PyMOL 3.1.3 on macOS 13.7,1.

When I double click a .pse or .pdb file, PyMOL opens normally and displays the molecule of interest.
If I think double click on another file, PyMOL opens a new window, the molecule displays, but now there is a seoncd state of the moleculeThe GUI shows the Global Frames control for switching between scenes. I also get this message:

	ObjectMolecule: Read crystal symmetry information.
	CmdLoad: "" appended into object "231129_EcNfo_WT_P028_9_refine_061", state 2.

Is this a bug? Or am I doing something wrong.

Mark

[PyMOL] Running pymol without launching window in batch

[Yarrow M. <yar...@gm...>]

I'm trying to run pymol in batch mode without launching the window. I am
running PyMOL 3.1.1.

Here is my code for an example script (test.py). I'm trying to run before
running the real script. In the command line I enter:
pymol -cq test.py


from pymol import cmd
import time

def main():
print("Starting PyMOL batch processing...")
cmd.load("3gbn.pdb")
do_stuff()
print("Loaded 3gbn.pdb")
time.sleep(25) # Ensure commands are processed
cmd.quit()

if __name__ == "__main_":
main()
I don't get any output. If I type:
pymol -c test.py
It appears that pymol starts and closes:

Any help on how to run a python script with pymol in batch without opening
the GUI would be appreciated.

[PyMOL] PyVOL plugin

[Vitali J. <jir...@gm...>]

Dear PyMol
I am trying to install the PyVol plugin and I have installed the msms on

How to set up the MSMS path on windows or on ubuntu?

Vol plugin

Re: [PyMOL] CASTp

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

Looks like the link has a viewer in the browser itself.
Upon experimenting I found that in the downloaded files, the .mouth and
.poc files are in pdb formats. I simply renamed them and loaded them
alongside the main pdb.
I then showed the other molecule as surface but it looked different than
what I saw on chrome using the url shared earlier.
I later realised the .mouth and .poc have broken fragments that can be open
in the display>sequence menu option in pymol.
I hope you can carry forward from here.

Hope it helps.

Saurabh Gayali
