Analyze 7.5 hdr into .mat file - Freesurfer

9 Apr 2010


      I want to import anlayze75 with a right direction (still).
I have those files:
subject.hdr
subject.img
And got warnings as:
--------------------------
INFO: could not find ~/subject.mat file for direction cosine info.
INFO: use Analyze 7.5 hdr->hist.orient value: 0, transverse unflipped (default).
INFO: if not valid, please provide the information in ~/subject.mat file
--------------------------
I know the orientation info should be provided somehow; but I don't
know how to do it.
I just tried to make a corresponding MAT file containing header info
by simply saving whole header info as
...
...
HRD=analyze75info('subject.hdr');
save subject.mat HDR
But I got another error as
-----------
unsupported matlab format 262149 (unknown)
MatrixMultiply: m1 cols 1 does not match m2 rows 4
Segmentation fault
-----------
*Does someone who handled Analyze75 format before know how to create a
corresponding MAT file?*
SG.
+I firstly tried import without MAT file, then I worked but with a
wrong direction (fig1).
I checked the header file.
It says 'Transverse unflipped' as default, which is also perplexing
because the import was made using the default orientation 'Transverse
unflipped' anyway.
