read_tree()

Bnode * read_tree

(

char *

filename

)

Reads a phylip format tree file.

Reads the tree file using a recursive approach.

Parameters

*filename

tree file name.

Returns

Bnode* a pointer to the root node of the tree.

tree_calculate_angle()

int tree_calculate_angle	(	Bnode *	node,
		int *	itip,
		float	tip_angle
	)

Calculates an angle for each node for plotting.

Parameters

*node	node.
*itip	the number of tip nodes passed.
tip_angle	the angular increment for each tip node.

Returns

int 0.

tree_delete_node()

int tree_delete_node

(

Bnode *

node

)

Deletes a node with all daughter nodes.

Parameters

*node

node.

Returns

int 0.

tree_read_node()

Bnode * tree_read_node	(	char **	handle,
		Bnode *	one
	)

Reads a node into a tree structure.

Parameters

**handle	pointer to the buffer holding the phylip format tree.
*one	one node.

Returns

Bnode* a pointer to the new node of the tree.

tree_rotate()

int tree_rotate	(	Bnode *	node,
		float	angle
	)

Adds an angle to all nodes.

The angle must be specified in radians.

Parameters

*node	node.
angle	rotation angle (radians).

Returns

int 0.

tree_show()

int tree_show

(

Bnode *

node

)

Shows a node with all daughter nodes.

Parameters

*node

node.

Returns

int 0.
