Analyze 7.5 is a file format, developed by the Mayo Clinic, for storing MRI data. An Analyze 7.5 data set consists of two files:
Header file (
Provides information about dimensions, identification, and processing history. You use the
analyze75info function to read the header information.
Image file (
) — Image
data, whose data type and ordering are described by the header file. You use
analyze75read to read the image data into the workspace.
The Analyze 7.5 format uses the same dual-file data set organization and the same file name extensions as the Interfile format; however, the file formats are not interchangeable. To learn how to read data from an Interfile data set, see Interfile Files.
The following example calls the
analyze75info function to read the
metadata from the Analyze 7.5 header file. The example then passes the
structure returned by
analyze75info to the
function to read the image data from the image file.
info = analyze75info('brainMRI.hdr'); X = analyze75read(info);
