Welcome to EzEditor2, a nucleotide and amino acid sequence editor that can be used together with EzBioCloud's Identify and comparative genomics services.
EzEditor2 is an improved iteration of the original EzEditor software.


EzEditor2 is a Java-based sequence alignment editor which enables the manipulation of both DNA and protein sequences for phylogenetic analysis. EzEditor2 has several features optimized to match initial computer-assisted alignments and subsequent phylogenetic analysis by enabling manual editing with references to biological information specific to the genes under consideration. It also provides various functions for editing rRNA alignment using secondary structure information and simultaneous editing for both DNA and their translated protein sequences and protein-coding genes.
