There are three major formats of alignment files - fasta, phylip and nexus. This tool can convert one type format (test.phy) to another type (test.fasta). Multiple files are allowed but must be uploaded as a zip file (putting them in a folder and zip the folder, for example, test.zip). If the size of the input file exceeds 8M, you can put it in a folder and submit the zipped folder (please do NOT zip input file). After submission, a unique web link will be generated for users to download the result of the analysis.
