Function Documentation

hand_select_consist()

int hand_select_consist	(	Bproject *	project,
		double *	mg_ang,
		int *	mg_index,
		int *	mg_select,
		int	sel_consist
	)

Sets consistent selection values in all (including unused) micrographs.

Parameters

*project	Project structure
*mg_ang	angles for micrograph selection, views 1 & 2
*mg_index	indices for micrograph selection, views 1 & 2
*mg_select	micrograph selection criteria, views 1 & 2
sel_consist	1 or 2, set other selection values to those of this view

Returns

int 0.

If a field-of-view contains more than two micrographs, the user can
only use two of them to do the handedness determination.  The unused
micrographs may need their selection values set to the same as those
in the used micrographs (views 1 and 2).  In addition, there may be
differences in the initial selection values for views 1 and 2.  This 
routine loops through the micrographs in a field-of-view and sets all
selection values to those of view 1 or 2.

project_get_handedness()

int project_get_handedness	(	Bimage *	mapA,
		Bproject *	project,
		double *	mg_ang,
		int *	mg_index,
		int *	mg_select,
		double	rad_min,
		double	rad_max,
		double	res_min,
		double	res_max,
		double	AmB_min,
		double	AB_min,
		int	diff_out,
		int	origins2,
		Bstring	outimg
	)

Determines handedness for all selected particles (sel > 0) in a project.

Parameters

*mapA	3D map (hand A)
*project	Project structure
*mg_ang	angles for micrograph selection, views 1 & 2
*mg_index	indices for micrograph selection, views 1 & 2
*mg_select	micrograph selection criteria, views 1 & 2
rad_min	minimum radius for FOM calculation (pixels)
rad_max	maximum radius for FOM calculation (pixels)
res_min	minimum resolution for FOM calculation (angs.)
res_max	maximum resolution for FOM calculation (angs.)
AmB_min	|FOMA - FOMB| must be this value or greater
AB_min	min. acceptable value for FOM of correct hand
diff_out	output difference of measured & predicted orientations
origins2	flag to determine origins for second view
outimg	prefix & suffix for output projection files

Returns

int 0.

Gets tilt-axis direction and rotation angle for a micrograph pair.
Then, loops through the selected particles in pair.  Sends data to
function get_handedness_from_tilt_pair, where handedness is
determined.  Statistics are calculated for each pair and sums for
global statistics are tabulated.
