Syntax

info = analyze75info(filename)
info = analyze75info(filename,'ByteOrder',byteOrder)

Description

example

info = analyze75info(filename) reads the header file of the Analyze 7.5 data set specified by filename. The function returns info, a structure whose fields contain information about the data set. Analyze 7.5 is a 3-D biomedical image visualization and analysis product developed by the Biomedical Imaging Resource of the Mayo Clinic. An Analyze 7.5 data set is made of two files, a header file and an image file. The files have the same name with different file extensions. The header file has the file extension .hdr and the image file has the file extension .img.

info = analyze75info(filename,'ByteOrder',byteOrder) reads the Analyze 7.5 header file with Big Endian or Little Endian byte ordering.
