Hi Charles,
You are right and I am wrong about the files needing to be loaded.
The object name has the pesky pdb file extension stripped off, so lets use the
object name instead of using Python to strip it off for us.
We no longer need to use glob.
We do need to the create a list of strings that encode the indexing of the
files.
This code worked for me with two files.
Adapt to your 30 or 300 files.
file_list = ['01','02']
[cmd.do("load model.000."+str(k)+"_minimized.pdb") for k in file_list]
object_list=cmd.get_object_list('(model.000.*_minimized)')
chains=[('A','F'),('B', 'F'),('C','F'),('D','F'),('E','F')]
run
C:\Users\user\AppData\Local\Programs\Python\Python38\lib\site-packages\pymol\pymol_path\Pymol-script-repo\list_hb.py
[cmd.do("list_hb chain F, chain A:E,
write_distances_file=hb_"+str(file)+".txt") for file in object_list ]
Best regards,
Blaine

Subject: [EXTERNAL] Re: hydrogen bond list for a series of files
Thanks, Dr. Mooers.
I modified a little.
It seems the pdb files need be loaded.
I put all the following lines in a file multifile_hb.pml
run
C:\Users\user\AppData\Local\Programs\Python\Python38\lib\site-packages\pymol\pymol_path\Pymol-script-repo\list_hb.py
import glob
load model.000.*_minimized.pdb
#chains=[('A','F'),('B', 'F'),('C','F'),('D','F'),('E','F')]
[cmd.do("list_hb chain F, chain A:E,
write_distances_file=hb_"+str(file)+".txt") for file in
glob.glob("model.000.??_minimized.pdb")]
A little not so perfect is that the output file,
hb_model.000.??_minimized.pdb.txt
Is is possible to do something like this
write_distances_file=hb_"+basename(file)+".txt"
Then the output will be
hb_model.000.??_minimized.txt
I tried, and this simple thing does not work.
Any suggestion?
Thanks!
Charles

Hi Charles,
Make sure that PyMOL's present working directory is where the pdb files are
stored.
Copy and paste each of the four lines below one at a time on the command line
in PyMOL.
run
list_hb.py<https://urldefense.proofpoint.com/v2/url?u=http-3A__list-5Fhb.py&d=DwQF-g&c=VjzId-SM5S6aVB_cCGQ0d3uo9UfKByQ3sI6Audoy6dY&r=k0gMbcsdOcdbPUNV5tW66KQSZfXL0ewVDPVBp7tqbks&m=X2B3s7D21CBjGtOAQJ2noNR7vnKXPiHiT2eLIRiSC18&s=KYQX_tOI8_HnmseLbJRMv7UTirG78evoaztp35Gg74E&e=>
import glob
chains = [('A','B'), ('A','C'), ('A','D'), ('A','E'), ('B','C'), ('B','D'),
('B','E'), ('C','D'), ('C','E'), ('D','E') ]
[[cmd.do("list_hb chain "+ str(i) +", chain " +str(j) + ",
write_distances_file=hb_"+ str(file) + "_" + str(i) + "_" +str( j) +
"_001.txt") for i, j in chains] for file in glob.glob("model.??.pdb")]
Note that you do not have to load the pdb files into PyMOL.
If you want to analyze more than 99 files and less than 999 files, add a third
question mark to the argument of glob.glob().
Best regards,
Blaine

Subject: [EXTERNAL] [PyMOL] hydrogen bond list for a series of files
Hi, Pymol users
Could you help me do this in an efficient way?
Let me describe the task I try to do.
I have a series of numerically ordered files, say model00.pdb model.01.pdb ……
model.30.pdb
All the pdb have the same protein composition, chain A, B, C, D, and E. Their
relative position is different in each file.
I would like to check the hydrogen bonds between, say, chain A and B.
Thanks to Prof. Robert L. Campbell, I can list the hydrogen bonds in one pdb
and print the list as the follows
list_hb chain A, chain B, write_distances_file=hb_A_B_01.txt
How can I process the 30 files in an efficient way? what if I have 300 pdb
files?
Shell script, python, or anything else?
Thanks!
Charles Chen
