[Chimera-users] Problem with DelPhi in chimera (labe boye)

Hi,
The Chimera v.6 that I used was the linux version NOT windows. The answer you got from the Delphi people sounds familiar to me which is why I switched to APBS interface on Chimera (works on both Windows and linux). The .dx file produced by APBS is read and contoured nicely by Chimera. If you need to ionize the structure, there is a Windows PDB2PQR executable as mentioned by Elaine (I understand that you're using Windows).
Cheers,
Boaz

We saw your Chimera bug report. However, the file you attached was not the ?.phi? file (electrostatic potential map) output from DelPhi. It was just the text output from the DelPhi program. If DelPhi runs successfully on your structure, it will create a separate file, with name ending in .phi, that is the electrostatic potential map.
If by ?cube? you mean Gaussian cube grid, Chimera does read that format.
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#volume>
However, this format is handled simply as a map that is not necessarily electrostatic potential, so it would require more steps in Chimera to get the coloring you want.
Best,
Elaine

Hi,
I ran into this Chimera/Delphi problem a few months ago (and discussed it with the Chimera/Delphi people). The latest Delphi version that I tried (8.4) produced a cube format file which formally can be read and contoured in the Chimera volume viewer. I hated the way the electrostatic surface produced that way looked and abandoned it. Delphi v. 6 which I have (and which I think Elaine used 3 years ago) produced the good old .phi which is file properly displayed in Chimera . I think one can still get hold of V.6 from the Delphi distribution site.
To avoid this mess I used the APBS interface of Chimera which worked fine and produced a nice, familiar style, looking electrostatic surface (see for example Fig. S10 in the supplementary of doi: 10.1093/nar/gkz604).

Hi,
Chimera is saying that your phi file output from Delphi contains inconsistent information, like maybe it got truncated. I do not know if it is possible to fix the phi file, sorry.
The DelPhi files that Chimera can read are from the academic version of DelPhi, as mentioned here:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#esp>
If you have some other version of DelPhi associated with a commercial package, maybe the format is different and Chimera does not know how to read it.
Linked to the last section of this tutorial, there is an example DelPhi phi file (3eebB.phi) that Chimera can read:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/surfprop.html>
I hope this helps,
Elaine

Hi
Hope you are doing good. I need your assistance regarding chimera. I'm working on virtual docking and need to prepare more than 10k ligands (in a single file as SDF) for docking process. I need to know that if chimera desktop latest version can fulfill my need. If yes please give me a tutorial pdf or video.
Regards
Waiting for a quick response

Hi
Thank you for your reply.
Could you please let me know which version of DelPhi academic version is
compatible with Chimera? Which DelPhi version was used to generate the
3eeb.phi file in the tutorial?
kindest regards,

It should be any DelPhi version that you get from the academic website, which was a link in this page I sent earlier:

?specifically this is their academic website <http://compbio.clemson.edu/delphi>
I don?t remember what version I used several years ago to make 3eebB.phi, but as far as I know the format didn?t change. It is possible it changed and we didn?t know about it, but we would need example(s) of the files.
If you believe you used the academic version of DelPhi but you get the error opening the phi file, you could try using Chimera menu Help? Report a Bug and attach your phi file so we could take a look at it. However, that does not guarantee it will be possible to fix.
I hope this helps,

Content-Type: text/plain; charset=utf-8
Hi Asmi Tariq,
This is not a bug, so please do not send mail to the bugs address.
There is no such PDF or video, sorry. However, I do know that lots of people use Chimera to prep many ligands. Here are some tips:
(1) You didn?t say what docking program you are using. Different programs take different input formats. Chimera would be used to prepare ligands and write them in mol2 format. If your docking program doesn?t take mol2, then Chimera is less useful for you.
(2) My guess is that it wouldn?t be practical/feasible to read one giant SDF file with all those ligands for prepping. If using Chimera, it would probably work better if you had individual files for the individual ligands instead, e.g. lig00001.sdf, lig00002.sdf, etc. Also the SDF needs to be 3D coordinates. if you have SDFs with 2D chemical diagrams, Chimera will NOT be able to prep them into reasonable 3D molecules.
(3) then you would have to manually figure out which command(s) to use to prep a single ligand. Probably you would need to use ?open? (open ligand file), ?addh?, ?addcharge? and ?write? (output mol2 file). There is usually some trial and error for you to figure out what command options you want. See the individual command help pages here:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/framecommand.html>
(4) After you have figured out which commands you want to use, then you would write a script to loop through your many ligands as discussed here in the programmer?s guide.
<http://www.rbvi.ucsf.edu/chimera/docs/ProgrammersGuide/basicPrimer.html>
P.S. I changed the subject line to something useful.
I hope this helps,
Elaine

OK,I tried all the three academic versions of DelPhi for windows; and none is working for me. I contacted the DelPhi supporters and SUGGESTED to use CUBE output format which isn't possible in Chimera. In the mean time, the two Chimera versions I installed read 3eeb.phi file from the tutorial.?I will report the problem.regards,

Hello,
That sounds like a problem with your DelPhi setup, or you didn?t wait long enough for the calculation to finish. Sometimes it takes several minutes.
Instead of DelPhi, you could try using PDB2PQR and then (on the resulting pqr file) using APBS. Chimera has interfaces to both of these:
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/apbs/pdb2pqr.html>
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/apbs/apbs.html>
?or you can use their web server directly, outside of Chimera:
<http://nbcr-222.ucsd.edu/pdb2pqr_2.1.1/>
<https://imsva91-ctp.trendmicro.com:443/wis/clicktime/v1/query?url=https%3a%2f%2fapbs%2dpdb2pqr.readthedocs.io%2fen%2flatest%2fdownloads.html%23web%2dservers&umid=A9632B4F-9A75-C205-9750-7484A8300BF7&auth=701951cf8dfb7cd99762e0f5be252082d875f1cf-082163e1d1ed2b88e4dc6a972a0664a6fa5833bb>
I hope this helps,
Elaine

The latest Delphi version that I tried (8.4) produced a cube format file which formally can be read and contoured in the Chimera volume viewer. I hated the way the electrostatic surface produced that way looked and abandoned it. Delphi v. 6 which I have (and which I think Elaine used 3 years ago) produced the good old .phi which is file properly displayed in Chimera . I think one can still get hold of V.6 from the Delphi distribution site.
