dear freesurfer team,

i experience trouble to compute the register.dat file when using tkregister2 to import an SPM2 BOLD brain volume f.img together with an 001.mgz structural file. segmentation and flattening worked flawlessly for that 001.mgz file (imported initially from an SPM2 anatomical data). here some examples of my desperate attempts:

tkregister2 --mov ANALYZE/f.img --s fs1 --regheader --noedit --reg register.dat

tkregister2 --mov ANALYZE/f.img --targ ANALYZE/cor.img --s fs1 --regheader --noedit --reg register.dat

tkregister2 --mov ANALYZE/f.img --targ ANALYZE/cfs1/mri/orig/001.mgz --s fs1 --regheader --noedit --reg register.dat

tkregister2 --mov ANALYZE/f.img --targ fs1/mri/orig/001.mgz --s fs1 --regheader --noedit --reg register.dat tkregister2 --mov ANALYZE/f.mat --targ fs1/mri/orig/001.mgz --s fs1 --regheader --noedit --reg register.dat tkregister2 --mov ANALYZE/f.hdr --targ fs1/mri/orig/001.mgz --s fs1 --regheader --noedit --reg register.dat

please, see error messages below. something seems to run wrongly when reading the f.mat file. i use matlab v7.1 with SPM2. the mat file initially was created as compressed mat file (v7 style), but then i converted the f.mat alsoto a v6 style = non-compressed, but no difference. content of the f.mat file is, after doing: 'load f.mat'

mat =

3.7499 -0.0312 0.0122 -128.3677 0.0325 3.6227 -1.2914 -110.0712 -0.0008 0.9686 4.8303 -86.1374 0 0 0 1.0000

==> are there somewhere out there clear instructions how to make SPM2 and freesurfer coexist ?

thanks, bye,

pisti
