The gene sequence and genetic feature variation between different individuals are very important for natural variation research. And the genome sequence and genetic features (always in GFF/GTF format) of reference is well established. In general the genomic sequence of different lines/accession are sequenced. The genetic features of variant individuals are also very interesting, while there no well established solution to transform the genetic features annotation of reference accession/line to other individuls. This pipeline tries transform the reference genetic fearures to variant individuls with genome sequence avaliable by whole-genome resequencing or de novo assembly . Here we provide a solution for inconsistent alignment problem which could lead to false positive splice sites disturb or ORF-shift predication. And whole genome MSA is all developped basing on the genetic features. GEAN could also use to transform the well annotated genetics feature of model species to phylogenetically nearby species with whole genome newly sequenced .
Using the gene annotation as anchors, GEAN could perform base-pair resolution whole-genome-wide sequence alignment and perform variant calling.

There are several functions are under testing and are included in the source code. The document for those functions will be released after testing. Best Practices for different aims could be found under example.
- whole genome wide pair-wise sequence alignment and variants calling for de novo assembly
- genome wide multiple sequence alignment using variant calling result
- transform maize reference genome annotation to de novo assembly
