GFinisher. bioinformatics tool developed in the Graduate Program in Sciences - Biochemistry at the UFPR

Easy and rapid to improve, refine and close your genome assembly.

GFinisher is an application tools for refinement and finalization of prokaryotic genomes assemblies using the bias of GC Skew to identify assembly errors and organizes the contigs/scaffolds with genomes references.

Requirements

Data


Resource


Enviroment

GFinisher developed in java plataform, you can use in most operating systems.

For the assembly of bacterial organisms, we observed a memory consumption of about 4Gb RAM.

Java Virtual Machine required (version 7 or up)

GFinisher requires and include jFreeChart library

Open-source

GFinisher is open-source, you can use, modify and redistribute freely.
