# When called with a tree string the `make_tree()` function return a baltic tree object:

treeString='((A:1.0,B:2.0):1.0,C:3.0);'
myTree = bt.make_tree(treeString)

# Otherwise you can import trees from newick, nexus or nextstrain JSON files

newickPath='/Users/myUsername/tree.newick'
myTree = bt.loadNewick(newickPath)

nexusPath='/Users/myUsername/tree.nex'
myTree = bt.loadNexus(nexusPath, absoluteTime = False)

nextstrainPath='https://nextstrain.org/charon/getDataset?prefix=/dengue/denv1'
myTree, myMeta = bt.loadJSON(nextstrainPath)
