Make a fasta file
WebUsing an fai index file in conjunction with a FASTA/FASTQ file containing reference sequences enables efficient access to arbitrary regions within those reference sequences. The index file typically has the same filename as the corresponding FASTA/FASTQ file, with .fai appended. WebTake all the sequences that form one individual cluster and build a multiple sequence alignment (MSA) with MAFFT/ClustalOmega or similar Take the MSA and build a phylogenetic tree with a Maximum-Likelihood approach like iqtree or similar Visualize the tree file with Jalview or similar

The table below shows each extension and its respective meaning. The compression of FASTA files requires a specific compressor to handle both channels of information: identifiers and sequence. For improved compression results, these are mainly divided in two streams where the compression is made assuming independence.
