float lininterp	(	float	y0,
		float	y1,
		float	x0,
		float	x1,

Here is the caller graph for this function:

process_bipoles()

void process_bipoles	(	gengetopt_args_info &	args,
		IGBheader *	h,
		vector< int > &	nodes,
		FILE *	out,
		int	first
	)

determine activations in bipolar recordings

Parameters

args	command line parameters
h	IGB header
nodes	nodes to analyze
out	output file
first	first time to analyze

An activation occurs if the amplitude of the signal is greater than phimin but does not exceeed phimax, and |dphi/dt| (center difference) exceeds dvdt The time of the greatest peak is recorded during the interval until the magnitude drops below phimin

To be an activation, the duration has to be between act_dur_min and act_dur_max, and minapd has elapsed since the last activation

Here is the caller graph for this function:

process_specifier()

bool process_specifier	(	char *	sp,
		set< int > &	nodes,
		int	max
	)

get list of specified nodes from a string: (([0-9]?[-([0-9]+|*))|*)[:[0-9]+] This mean you can specify n -> node n n0-n1 -> nodes n0 to n1 inclusive n-* -> all nodes starting at n

• -> all nodes To any of these, :d may be appended on the end signifying stride d

Parameters

sp	user specified string of nodes
nodes	set of nodes
max	number of nodes in model

Postcondition

nodes contains all the specified nodes

Returns

true iff all nodes have been specified
