 ### Complexsearch
-The `easy-complexsearch` module is designed for searching single or multiple query protein complexes (supported input formats: PDB/mmCIF, flat or gzipped) against a target database of protein complex structures. It reports the similarity metrices between the complexes (e.g., the TMscore).

 ##### Complex Report
-`easy-complexsearch` also generates a report format (prefixed `_report`), which provides a summary of the inter-complex chain matching, including identifiers, chains, TMscores, rotation matrices, translation vectors, and assignment IDs. The report includes the following fields:

 ### Cluster search results 
-The following command aligns the input structures all-against-all and keeps only alignments with 80% of the sequence covered by the alignment (-c 0.8) (read more about alignment coverage [here](https://github.com/soedinglab/MMseqs2/wiki#how-to-set-the-right-alignment-coverage-to-cluster)). It then clusters the results using greedy set cover algorithm. The clustering mode can be adjusted using --cluster-mode, read more [here](https://github.com/soedinglab/MMseqs2/wiki#clustering-modes). The clustering output format is described [here](https://github.com/soedinglab/MMseqs2/wiki#cluster-tsv-format).
