Hi,
I'm not sure if this is a bug report or a feature request. I have been using mri_convert to convert dicoms to nii.gz and mgz files, and I have noticed some discrepancies when reading the volumes in with MRIread in either matlab or octave. The volumes differ in their support of the flip angle, tr, te, and ti fields (I realize some of this may be due to file type differences). Thought the standard output of mri_convert shows the expected values.
In the mgz file the TR seems to be rounded i.e. 50 instead of 50.000000745058060 in the nii.gz
In the mgz file the flip angle and te are recorded FA 0.52.... while in the nii.gz it is 0 te 10.39... while in the nii.gz it is 0
The ti value appears strange to me in the mgz ti = -1 while in the nii.gz it is 0
I have generated two files using mri convert off of the same MR volume as a test case: /cluster/hbot/agario_p2_2/dcm/020_t1_fl2d_tra_TEMP/004/877000-000020-000003.dcm
/cluster/hbot/agario_p2_2/dcm/020_t1_fl2d_tra_TEMP/004/volume.nii.gz
/cluster/hbot/agario_p2_2/dcm/test.mgz
These files were generated using /usr/local/freesurfer/stable5_1_0/
Thanks, D
