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
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 MATLAB® workspace.
Note The Analyze 7.5 format uses the same dual-file data set organization and the same filename 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
to read the metadata from the Analyze 7.5 header file. The example
then passes the
info structure returned by
analyze75read function to read the image data
from the image file.
info = analyze75info('brainMRI.hdr'); X = analyze75read(info);
