Examples

Prepare to run

conda activate RF2
cd example

Example 1: predicting the structure of a monomer

../run_RF2.sh rcsb_pdb_7UGF.fasta -o 7UGF

Example 2: predicting the structure of a heterodimer with paired MSA

../run_RF2.sh rcsb_pdb_8HBN.fasta --pair -o 8HBN

Example 3: predicting the structure of a heterotrimer with paired MSA

../run_RF2.sh rcsb_pdb_7ZLR.fasta --pair -o 7ZLR

Example 4: predicting the structure of a C6-symmetric homodimer

../run_RF2.sh rcsb_pdb_7YTB.fasta --symm C6 -o 7YTB

Example 5: predicting the structure of a C3-symmetric heterodimer (A₃B₃ complex) with paired MSA

../run_RF2.sh rcsb_pdb_7LAW.fasta --symm C3 --pair -o 7LAW

Expected outputs

Predictions will be output to the folder 1XXX/models/model_final.pdb. B-factors show the predicted LDDT. A json file and .npz file give additional accuracy information.

Additional information

The script run_RF2.sh has a few extra options that may be useful for runs:

Usage: run_RF2.sh [-o|--outdir name] [-s|--symm symmgroup] [-p|--pair] [-h|--hhpred] input1.fasta ... inputN.fasta
Options:
     -o|--outdir name: Write to this output directory
     -s|--symm symmgroup (BETA): run with the specified spacegroup.
                              Understands Cn, Dn, T, I, O (with n an integer).
     -p|--pair: If more than one chain is provided, pair MSAs based on taxonomy ID.
     -h|--hhpred: Run hhpred to generate templates
