A large number of alignment statistics and properties are computed in order to facilitate their comparison. Additional alignments can be uploaded and integrated in the comparison.
If you want to compute your alignments locally, the stand-alone alignment programs can be downloaded here.
Online evaluation is currently not available, please use the stand-alone programs.
