Function Documentation

readBRIX()

int readBRIX	(	Bimage *	p,
		int	readdata
	)

Reading a BRIX image file format.

Parameters

*p	the image structure.
readdata	flag to activate reading of image data.

Returns

int error code (<0 means failure). A 3D image format intended for use with the 'O' program. It has a text header of 512 bytes (fixed size). File format extension: .brx. Identifier: ':-)' (byte 0). Data type: byte, packed as 8x8x8 pages. The header specifies the following keywords: origin: origin extent: size in pixels grid: unit cell size in pixels cell: unit cell parameters in angstroms and degrees prod: scale to convert original map to byte plus: average sigma: standard deviation of original map The voxel size is given by the unit cell size divided by the grid size (Since the unit cell size may not fit exactly onto the grid, the voxel size as calculated from the unit cell size and grid may not be accurate).

writeBRIX()

int writeBRIX

(

Bimage *

p

)

Writing a BRIX image file format.

Parameters

*p	the image structure.

Returns

int error code (<0 means failure). A 3D image format intended for use with the 'O' program.
