示例1: action

# 需要导入模块: from csv import DictReader [as 别名]
# 或者: from csv.DictReader import items [as 别名]
def action(args):
    def newname(leaf, newname):
        leaf.name = newname
        return leaf

    tree = Phylo.parse(args.tree, args.tree_type).next()
    leafs = (leaf for leaf in tree.get_terminals())

    if args.info:
        info = DictReader(args.info, fieldnames = ['seqname','newname'])
        info = {i['seqname']:i['newname'] for i in info}

        # for newick trees :s will be replaced by |s
        if args.tree_type == 'newick':
            info = {s.replace(':', '|'):n for s,n in info.items()}

        leafs = (l for l in leafs if l.name in info)
        leafs = (newname(l, info[l.name]) for l in leafs)

    if args.remove_word:
        leafs = (newname(l, re.sub(args.remove_word, '', l.name)) for l in leafs)
        leafs = (newname(l, l.name.strip()) for l in leafs)

    leafs = (newname(l, args.add_prefix + l.name) for l in leafs)
    leafs = (newname(l, l.name + args.add_suffix) for l in leafs)

    # do this last
    if args.tree_type == 'newick':
        leafs = (newname(l, l.name.replace(' ', '_')) for l in leafs)

    # execute changes and write tree
    list(leafs)
    Phylo.write(tree, args.out, args.tree_type)
