 # Phables: from fragmented assemblies to high-quality bacteriophage genomes
 
 Phables is a tool developed to resolve bacteriophage genomes using phage bubbles in viral metagenomic data. 
-It models cyclic phage-like components in a viral metagenomic assembly graph as flow networks, models as a 
+It models phage-like components in a viral metagenomic assembly graph as flow networks, models as a 
 minimum flow decomposition problem and resolves genomic paths corresponding to flow paths determined. 
 Phables uses the [Minimum Flow Decomposition via  Integer Linear 
 Programming](https://github.com/algbio/MFD-ILP) implementation to obtain the flow paths.
