[ ge, lastfile ] = ge_series_read(examPath, seriesPath)
examPath - string path to exam directory
seriesPath - string path to series directory,
relative to examPath
reads the volume of files in seriesPath, which is stored
under examPath (it can return the name of the last file read).
The files are assumed to be arranged in series subdirectories
below the examPath, so series files would be located as such:
examPath/seriesN/*.MR or examPath/seriesN/I.*. The function
will try to find all *.MR or I.* files and determine the
correct numerical order of the image files.
The function assumes the GE files are big endian. This is
an example of the returned struct, where ge.img contains
the image volume data:
ge =
pix_hdr: [1x1 struct]
img.offset: 8432
su_hdr: [1x1 struct]
ex_hdr: [1x1 struct]
se_hdr: [1x1 struct]
hdr.image: [1x1 struct]
img: [256x256x11 double]
