Re: [PyMOL] Deleting and Loading multiple SDF files
Hi Renuka,
Please keep all PyMOL-related correspondence on the mailing list. That way,
other people can find the answers by reading the mailing list or searching
the web.
Your task is now getting a little more complicated. I think you'll probably
want to define some Python functions and use them. It's useful to know that
using the distance command with mode=2 will show polar contacts. Also,
distance objects with names starting with an underscore won't show up in the
GUI.
I'd do something like this:
1. Define some functions in a Python file that you can use via run (or
perhaps in your .pymolrc). [see
http://www.pymolwiki.org/index.php/Python_Integration and
http://www.pymolwiki.org/index.php/Script_Tutorial]. You'll need to pass the
name of your protein to these functions.
import os
from pymol import cmd
def loadclust(filename,protname):
cmd.load(filename)
dir,fname = os.path.split(filename)
# PyMOL automatically names the object by the filename
fname,extension = os.path.splitext(fname)
# cluster_4 -- 4
custernum = fname.split('_')[1]
# hidden from GUI display because it starts with _
polarname = '_polar_'+clusternum
cmd.dist(polarname,fname,protname,mode=2)
cmd.extend('loadclust',loadclust)
def delclust(filename):
dir,fname = os.path.split(filename)
# PyMOL automatically names the object by the filename
fname,extension = os.path.splitext(fname)
# cluster_4 -- 4
custernum = fname.split('_')[1]
# hidden from GUI display because it starts with _
polarname = '_polar_'+clusternum
cmd.delete(fname)
cmd.delete(polarname)
cmd.extend('delclust',delclust)
2. Then you should be able to use a similar procedure to
before. Remember that you now need to delete things and pass the name of
your protein to the functions so that polar contacts can be displayed
correctly:
for i in glob.glob(Model_1/cluster_*.sdf): loadclust(i,myprotein)
analyze things
for i in glob.glob(Model_1/cluster_*.sdf): delclust(i,myprotein)
for i in glob.glob(Model_2/cluster_*.sdf): loadclust(i,myprotein)
Unfortunately, I don't have any SD files on hand, so I haven't tested these!
Some modification may be necessary. You should also check out the script
that Jason linked.
Cheers,
-Michael

Dear Michael
Thanks for your detailed reply. This is what exactly i needed. Now i want
to find the hydrogen bonding between each cluster files and the protein. So
i do the following step
cd /home/user
import glob
then I load the Model_1 files with
for i in glob.glob(Model_1/cluster_*.sdf): cmd.load(i)
Now hydrogen bond should be displayed between protein and
Model_1/cluster_*.sdf. Polar contacts in different colors would be more
appreciated.
Could you please attach your script in the above command, so that all the
cluster_*.sdf is loaded and its polar contacts is displayed in one press.
Thanks in advance
Renuka.

Hi Renuka,
If I understand correctly, this is what you want to do:
1. Load up all of the cluster*.sdf files in Model_1.
2. Analyze them
3. Delete them
4. Load up all of the cluster*.sdf files in Model_2.
5. Analyze them
6. Delete them
etc.
If that's right, I think the easiest thing is just to change to the
directory that contains your Model_N subdirectories. In your example, that
would be:
cd /home/user
import glob
then load the Model_1 files with
for i in glob.glob(Model_1/cluster_*.sdf): cmd.load(i)
then analyze them. It sounds like you're analyzing them by hand; if you're
analyzing them by running some scripts, we can probably help to automate
that process as well.
After analyzing them, (and saving your results!), you'll want to delete the
current batch of cluster files and load the new ones:
delete cluster_*
for i in glob.glob(Model_2/cluster_*.sdf): cmd.load(i)
Note that you only have to type import glob once.
Hope that helps,
-Michael

Dear Pymol users
I have to do TWO jobs simultaneously in
PYMOL.
JOB 1: Load multiple *sdf files
I have set of ligand files in *.sdf
format as follows:
/home/user/Model_1/cluster_1.sdf
/home/user/Model_1/cluster_2.sdf
/home/user/Model_1/cluster_3.sdf
/home/user/Model_2/cluster_1.sdf
/home/user/Model_2/cluster_2.sdf
/home/user/Model_2/cluster_3.sdf
/home/user/Model_3/cluster_1.sdf
/home/user/Model_3/cluster_2.sdf
/home/user/Model_3/cluster_3.sdf
I've got an answer from one of the
PYMOL user as:
PyMOLimport glob
PyMOLfor i in
glob.glob(cluster_*.sdf): cmd.load(i)
But this command works only in the
present working directory. For the next try I have to change my
directory every time. Like:
cd /home/user/Model_1/
PyMOLimport glob
PyMOLfor i in
glob.glob(cluster_*.sdf): cmd.load(i)
cd /home/user/Model_2/
PyMOLimport glob
PyMOLfor i in
glob.glob(cluster_*.sdf): cmd.load(i)
cd /home/user/Model_3/
PyMOLimport glob
PyMOLfor i in
glob.glob(cluster_*.sdf): cmd.load(i)
Could you please tell me how to load
these multiple *.sdf files in one command without changing the
directory?
JOB2: Delete multiple *.sdf files
I have to analyze cluster_*.sdf files
of several 100 directories.
So when I load cluster_*.sdf files from
directory Model_2, the already loaded cluster:*.sdf files from
Model_1 should be deleted.
Like wise when I load cluster_*.sdf files
from directory Model_3, the already loaded cluster:*.sdf files from
Model_2 should be deleted.
I am not good in programming. Could
anybody help me in scripting to sort out this problem?
Thanks in advance.

Renuka

Re: [PyMOL] Deleting and Loading multiple SDF files
Hi Renuka, Check out the loadDir PyMOL script ( http://www.pymolwiki.org/index.php/LoadDir). You can do stuff like, # load all PDBs in the directory ../ loadDir ../, *.pdb # load all SDFs in ../../mySDFs loadDir ../../mySDFs/state*.sdf Cheers, -- Jason On Wed, Sep 22, 2010 at 9:12 AM, Renuka Robert renukarob...@ymail.comwrote: Dear Pymol users I have to do TWO jobs simultaneously in PYMOL.
