Re: [ccp4bb] [ccp4bb] mmCIF files from PDB format for AlphaFill

Hi Nick I noticed this today when I was researching the differences between mmCIF and modelCIF - but thanks anyway. I haven't tried running it yet, but the important thing for me is to be able to convert my bare-bones PDB format files to something that AlphaFill will accept - and as the PDB-R

Hi Harry, I did stumble upon this python mmCIF handler for modelCIF: https://github.com/ihmwg/python-modelcif/blob/main/examples/README.md Maybe this will have something of use to your efforts? Best, Nick Clark Nicholas D. Clark (He/Him) PhD Candidate Malkowski Lab University at Buffalo Depa

Re: [ccp4bb] [ccp4bb] mmCIF files from PDB format for AlphaFill

Hi folks I’ve made considerable progress in getting to the bottom of this problem. From what I can gather, AlphaFold writes “modelCIF”, which is not quite the same as “mmCIF”, and just saying “CIF” is not unambiguous. So I guess I should have been more aware of this when posting my original que

Re: [ccp4bb] mmCIF files from PDB format for AlphaFill

Many thanks to all that replied. Ida’s suggestion of pdb2cif from the PDB-REDO people is the only one that’s worked to date (“worked” in this context means produces a CIF that AlphaFill accepts without complaining - can’t imagine why). Now off to play with my voids… As they say, standards are

Re: [ccp4bb] mmCIF files from PDB format for AlphaFill

Dear Harry, You could also try to use pdb2cif from the cif-tools: https://github.com/PDB-REDO/cif-tools. The only strict requirement for a PDB formatted file is that it has a HEADER at the first line. After installation, running from the command line is as simple as: pdb2cif file.pdb . Best

Re: [ccp4bb] mmCIF files from PDB format for AlphaFill

Harry, After a little digging, it seems this was previously reported as an issue to AlphaFold… see: https://github.com/google-deepmind/alphafold/issues/252 There are a few options others recommended or got to work in the comments. Notably, MAXIT was used: “Huiwenke: MineProt (https://github.com

Re: [ccp4bb] mmCIF files from PDB format for AlphaFill

Hi Martin, Marcin, Arturo, Avinash First off, I’m **NOT** saying that there’s anything wrong with the CIF files produced by these routes - just that AlphaFill doesn’t like them (it *does* like CIFs from AlphaFold - > alphafill process alphafold.cif filled.cif > 1DKE =-

Hi folks I am in the situation of having coordinates of apoproteins (i.e. polypeptide chains without prosthetic groups) in PDB format - but I need them in mmCIF format so I can run them through a locally built copy of AlphaFill. I need something I can install locally, so web services are a no-n
