 Modelling setup:
-
-
-Special features here:
+- Classic ColabFold setup with PDB coordinates and scores JSON and link to UniProt
+- Two custom model quality scores (ipLDDT, iPAE)
+- Experimental validation of binding and only validated or known interactions exported to 3D-Beacons
+- Four different modelling setups (PPI screening, relaxed models of selected screening results, full holoenzyme complex, design of protein-peptide complex)
+
+Special features here compared to PRC-complexes script:
+- UniProt-link: deal with subsets of sequences and with old versions and fixed cache of UniProt data (keyed also on entity sequence)
+- Use of modelcif.reference.SeqDif to deal with mismatches between UniProt and entity sequence
+- Deal with synthetic constructs (design) which do not have a link to UniProt
+- Custom cut of JSON scores for PAE and pLDDT for some relaxed models
+- Updated _get_cf_config function to deal with null values in ColabFold's config.json and to reset tpl_db and tpl_db_version if no templates used
 
 Content:
 - translate2modelcif.py : script to do conversion (run in virtual environment with same setup as Docker container here but with OST 2.8 and very latest main branch of python-modelcif and python-ihm from 20.6.2024)
 - modelarchive_submission.zip: example inputs to convert selected complex from this set, compressed
 - expected_output_modelcif.zip: compressed output from running conversion of modelarchive_submission with the following command :
-
 `python3  translate2modelcif.py ./modelarchive_submission ./modelcif  --no-extra-files`
