HADDOCK run could not be processed
ezequieltijerina13:
Hello , I am having difficulty uploading a file to HADDOCK. I keep receiving an email that states "PDB file is incorrectly formatted. Is there any way I could fix the problem? I have attached the file to this message.

Thanks for posting on the 3DNA Forum!
Where/how did you get the dna.pdb file you attached?
Could you please try the attached dna-new.pdb file and report back if it works?
Best regards,
Xiang-Jun

I submitted the file you sent me to HADDOCK and now the emails says "Second pdb file contains an unknown amino acid or nucelic acid base DT". Make sure to use three letter code for bases and amino acid. I got this file from 3D-Dart. I have attached two file to this email. The file under the name of "DNA- new" is the file you sent me a while ago and the file with the name of "DNA" is the original file. Please help me out with this problem.
xiangjun:
DT is a standard nucleic acid base name for T in DNA, as of PDB format v3.x (if I remember it correctly). So the error message from HADDOCK means that it is strict (picky) with its input of PDB format. As a test, you may download the DNA structure (e.g., 355d) from the RCSB PDB, and submit it to HADDOCK to see what happens.
I've re-created a new version of the PDB filedna-new2.pdb (attached) for you to try: it has T instead of DT etc.
Best regards,
Xiang-Jun
As a side note, such HADDOCK-related questions are better directed to its creators/maintainers. They know exactly what PDB format they support, and may provide you some working examples.

Hello, I'm very thankful for you help ,but there is still an error. "It says incorrectly formatted and please align the columns of your PDB properly". I'm not sure how to fix the problem. I have attached all 3 pdb files. DNA.pdb being the original file, dna-new.pdb being the first file you sent me and finally dna-new2.pdb being the final file you just sent me.
