Details

The trees in this release were generated with the following command line:

bash global_tree_gisaid_start_tree.sh -i [gisaid.fasta] -p [previous_iteration] -t 250

[gisaid.fasta] is the fasta file of high coverage and complete raw sequences from GISAID up to and including the date in the title of the release, determined by the 'submission date' filter on a GISAID data feed

[previous_iteration] is the filepath of the previous release, this is used to provide the excluded_sequences.tsv and ft_SH.tree files as the starting points of the current iteration.
