RGFA, an implementation of the proposed GFA specification in Ruby. It allows the user to conveniently parse, edit and write GFA files. Complex operations such as the separation of the implicit instances of repeats and the merging of linear paths can be performed. A typical application of RGFA is the editing of a graph, to finish the assembly of a sequence, using information not available to the assembler. We illustrate a use case, in which the assembly of a repetitive metagenomic fosmid insert was completed using a script based on RGFA.

The Graphical Fragment Assembly (GFA) is a proposed format which allow to describe the product of sequence assembly. This gem implements the proposed specifications for the GFA format described under https://github.com/GFA-spec/GFA-spec/blob/master/GFA-spec.md as close as possible.
