Checks that the dihedral angles are reasonable and produces a file with the ones which are not. The minimal configuration file for QualityAssessment is:
command=QualityAssessment pdb=QA.pdb
It can be run from the command line:
FoldX --command=QualityAssessment --pdb=QA.pdb
FoldX uses output-file as a tag to label different outputs from different commands in batch runs. After running SequenceOnly you'll get one file to look at. Given output-file="TAG" the output file is. SD_TAG.fxout -> sequence information If you don't set output-file, TAG will be the pdbId of the first pdb on the batch.
