Re: [PyMOL] Session scene compatibility with MacPymol?
For what it's worth, for teaching/training (and general research use), I've
always recommended using pml scripts instead of pse sessions. Turning on
logging can help with tracking what should end up going into the pml.
It's a little more work, and requires a little more forethought - but it's
also something that essentially never has issues with different PyMOL
versions. If anyone's curious, the only one I ran into was when PyMOL
changed how density maps were interpreted ("just load this block of density
over this region" to "treat this density as a seed for symmetry
expansions") around the 1.4 -> 1.5 transition.
Best,
Pete

Re: [PyMOL] no module named multiarray -- autodock plugin
Blake, From the stack trace you posted, it looks like the import that needs to be changed is in /usr/share/pyshared/numpy/core/__init__.py , not autodock.py . But before changing things there, it might be worth checking from the python interpreter (aka if "import multiarray" throws ImportError, does "from numpy.core import multiarray"?).

Re: [PyMOL] no module named multiarray -- autodock plugin
Hi Blake, I haven't used the autodoc plugin, but from your stack trace (and a quick check of the numpy install on my system) you may be able to resolve this by changing the "import multiarray" statement to "from numpy.core import multiarray".

Re: [PyMOL] loadDir script
Hi James, Assuming your going from the pymol wiki loadDir script; you'd need to change glob(c) loop (sort the list in your preferred order before the loop, rather than using the result list unmodified). If I'm understanding your problem correctly (numbered pdb files being loaded as 1.pdb, 100.pdb, 2.pdb ... instead of 1.pdb, 2.pdb, ... 100.pdb) it might be easier rename your pdb files so that the default string sorting from glob matches the numerical order you want. Using the same example, the filenames would change to 001.pdb, 002.pdb, ... 100.pdb.

Re: [PyMOL] Newbie question: launch PyMOL from a link
I suspect this depends on the browser you're using. If you're serving the PDB files with an appropriate MIME-type, and the browser is configured to open files of those types with pymol, then things should work. That said, going through pymol through a web interface seems like it might be more complications than it's worth.

Re: [PyMOL] Problem Opening Session File
The handling of density maps changed with (I believe) version 1.5 - earlier versions would just load the map as given, later ones appear to try to do symmetry expansion (even if the map isn't covering the ASU). I've seen this result in a similar error message when loading session files (with electron density, created in 1.4) with 1.5. My solution has been to stick with 1.4. However, I don't generally use multi-state session files, so I don't know if the electron density problem is related to the multi-state problem or not.

Re: [PyMOL] Using cmd.png with ray=False still ray traces the image
It may be worth trying pymol 1.4 (instead of 1.5) - although this
shouldn't make a difference, it might provide some more information (you
also mentioned that you've got a large scene - depending on composition
1.4 may use less memory than 1.5).
You may also want to try using a pml script vs python (start pymol with
"-q -c your_raytrace_script.pml" arguments) and see if that helps, or at
least breaks in different ways.

This actually renders my scene twice. I've tried cmd.do and it does the

Re: [PyMOL] v1.5.0.1: maps and sessions bug
Hi Jason, This is with the 1.5.0.1 release (source build from pymol-v1.5.0.1.tar.bz2, md5 8d44de94cff8bce79ce521a1116b0760).

[PyMOL] v1.5.0.1: maps and sessions bug
Anyone thinking about upgrading to 1.5 should be aware that there's a bug in loading session (pse) files containing map objects. Loading pse files (I checked ones created with 1.2 or 1.4) deletes these objects and reports an error: "ExectiveSetSession-Error: after names.\nExectiveSetSession-Warning: restore may be incomplete." The isomesh/isosurface objects created from the maps aren't deleted, but they're empty (aka not displaying when enabled). Reconstructing the same session from a script didn't show any problems.

Re: [PyMOL] PyMol memory, disk, and CPU usage
I've run into similar situations in the past, although in my case usually due to large maps (a 3.5 MB pdb file, or even a set of them, typically requires less memory than a ~50MB electron density map). In my experience, it's much better to load things from scripts (pml) rather than storing things in session files (pse). I may be remembering incorrectly, but from previous mailing list discussions I believe the higher memory usage for pse files was due to overhead for python de-pickling. You may also want to check your graphics drivers - a friend of mine was having some pymol performance problems that turned out to be driver related.

Re: [PyMOL] PyMol 1.4 not running on Ubuntu Linux 11.10
Hi John, I don't think you need a re-install. My take on the problem is that using the repositories installs the pymol libraries to the system python (not sure offhand which that is for ubuntu 11.10). But pymol is apparently trying to start up with "/usr/bin/env python", which is picking up the python you've got installed in /usr/local. Short version - try edit pymol (probably /usr/bin/pymol) to hard-code the system python. Pete John Ladasky wrote: > Hi folks, > > I just upgraded my Ubuntu Linux installation to 11.10.

Re: [PyMOL] Fetching scripts
Hi, From a security perspective, it seems like the ideas on the wiki page are all related to securing the remote source. It might be worth considering what could be done to minimize how much pymol has to trust the remote source or the network. A few ideas: - Sandboxing would be ideal, but I don't know if there's infrastructure in python to support it. It might be easier to filter fetched scripts to only allow a restricted subset of python functions (the ast library looks like it might make this a bit easier). If a script can't access the network or hard disk, then it doesn't need to be trusted as much. - The wiki doesn't appear to support SSL. So that means trusting the network to get to the wiki correctly, in addition to the wiki itself. I don't have any good ideas for how to work around this one.

Re: [PyMOL] Pymol segmentation fault
> Does anyone have any thoughts?
Two things to try that may or may not help:
1. Check if the problem persists when running pymol in single-threaded
mode ("cmd.set('max_threads',1)"). libpthread in the trace might
indicate that one of the libraries is having issues with multiple threads.
2. On Kubuntu 8.04.3 LTS x64, I can't reproduce the problem with 1.2
from svn trunk. This is using Tcl/Tk 8.4 (with pymol using it's own
source build of python 2.4.2, which may or may not be relevant); so
installing Tcl/Tk 8.4 instead of 8.5 (source or binary) might help
resolve the problem, or at least eliminate one possible source.

Re: [PyMOL] compilation problem with the latest pymol
Looks like you need to install the appropriate python-dev package (or otherwise point setup.py to the appropriate include directory if you build python from source).

Re: [PyMOL] get color function?
The way I use (which I'm sure could be improved), is to get the color index with "iterate sele, print color", followed by "print cmd.get_color_index( idx )". This gives you the rgb tuple for the color on 0-1 scale. I'd be curious to know if there's a way to avoid the iterate step, or get the color name (instead of index or rgb values), but haven't had the time to dig into it.

Re: [PyMOL] map for one molecule
> Is it possible to load a map to only cover the molecule and not the > complete asymmetric unit? Or is this only possible at the time of > creating the map? Yes and no. For displaying a map, if you give a carve option to isomesh or isosurface, it'll only display around a molecule (or other selection). But when you load the map, it's still over the same range (so the display may change to accommodate that). > > Thanks in advanced, > Ariel >
Re: [PyMOL] advice for the novice movie maker
I wouldn't claim it's necessarily the best way, but if I've had decent luck with scripting the transitions (either pymol or python) to generate a set of images. From there, it's fairly easy to encode a movie with ffmpeg or mencoder. But it probably depends on the type of movie you're trying to make. Pete Thomas S. Leyh, Ph.

Would this work > to run this from within pymol? With my usual way of installing pymol is to build most of the dependencies from source, including python. This copy of python gets sym-linked to pymol.python for building pymol (aka pymol.python setup.py build , etc in the pymol source directory) and is only used for running pymol. If you've installed things this way, then "pymol.python setup.py install" for your package should work, assuming your environmental python environmental variables are kept straight. But this is something I haven't needed to test, so if Warren says it's not possible he's probably found a problem with this approach I missed. Pete
Re: [PyMOL] .phs file open in PyMol

I assume I need to convert the file somehow first, I usually use > mapman for this utility but don't see an option for .phs files. First, you need to calculate a map. This is a calculation rather than a format conversion (which is why mapman doesn't have an option for this format). Assuming that .phs is a phases formatted file, you can use fsfour to calculate a map (although you'll probably have to convert that phases formatted map to ccp4 or xplor map format). You could also use the CNS or CCP4 packages, although in either case you'll have to convert the reflection file. Pete

If lack of memory is the problem, try loading your scene manually or through a script instead of using a session file. For reasons I don't recall at the moment, pymol uses more memory with a pse file than with the same objects loaded through a script (you could check the list archives for more details if you're curious). > PyMOL simply crashes under Windows Vista Home Premium as well as under > Ubuntu Linux v8.04 LTS without error report. My dual OS system is a Not sure about windows, but with linux you should get some level of messages by launching from a command prompt instead of an icon. If you're running out of memory, you'll get a core dump message (at least, that the usual symptom on my systems. > both OS are 32 bit and therefore to my (limited) knowledge cannot handle > more than 2 GB in a single task, RAM limitation might still be an issue You might want to have top running in a different terminal so watch how much memory pymol is trying to use (or is able to use before crashing).
[PyMOL] scripting apbs visualization?
Hi, Does anybody have suggestions for the simplest way to script loading an apbs grid and displaying the molecular surface colored by charge (possibly changing the low/high values as well)? I can do this interactively, but have come up blank trying to script this. Thanks, Pete
Re: [PyMOL] export surface
Odds are you've heard back from the mapman people by now. But if you haven't, if you've got a map that mapman says is too large you need to increase (or set) the MAPSIZE environmental variable. aka $ mapman MAPSIZE 2000 instead of $ mapman Pete Vahdati N. wrote: > Dear Pymol users, > > Is it possible to export/save surface files from within pymol? > > I am loading a binary ccp4 volume/surface file into pymol and would like to > export it as another format or simply the same format but in alphanumeric. > This is because I am interested in knowing the coordinates of the centre or > origin of my volume to use in my follow up analysis. > > I don't seem to be able to use MAPMAN which seems to be the usual tool to > convert map file formats.
