INTRODUCTION
|
PPR-Meta is designed to identify metagenomic sequences as phages, chromosomes or plasmids. The program calculate three score reflecting the likelihood of each input fragment as phage, chromosome or plasmid. PPR-Meta can run either on the virtual machine or physical host. For non-computer professionals, we recommend running the virtual machine version of PPR-Meta on local PC. In this way, users do not need to install any dependency package. If GPU is available, you can also choose to run the physical host version. This version can automatically speed up with GPU and is more suitable to handle large scale data.
