External Email - Use Caution
Hi:
I used the following commands:
dt_recon --i sub-OAS30003_ses-d1631_run-01_dwi.nii.gz --b sub-OAS30003_ses-d1631_run-01_dwi.bval sub-OAS30003_ses-d1631_run-01_dwi.bvec --s OAS30003_MR_d1631 --o dt_recon_result cd dt_recon_result
mri_vol2vol --mov lowb.nii.gz --targ $SUBJECTS_DIR/OAS30003_MR_d1631/mri/aseg.mgz --inv --interp nearest --o $SUBJECTS_DIR/OAS30003_MR_d1631/mri/aseg2diff.mgz --reg register.dat --no-save-reg
mri_segstats --seg $SUBJECTS_DIR/OAS30003_MR_d1631/mri/aseg2diff.mgz --ctab /home/gonzalorojascosta/freesurfer/FreeSurferColorLUT.txt --i fa.nii.gz --sum fa.stats
And, to view the results, I used:
freeview -v $SUBJECTS_DIR/OAS30001_MR_d0757/mri/brain.mgz $SUBJECTS_DIR/OAS30001_MR_d0757/mri/orig.mgz $SUBJECTS_DIR/OAS30001_MR_d0757/mri/aseg.mgz:colormap=lut:opacity=0.2 fa.nii.gz:reg=register.dat:colormap=heat -colorscale -viewport coronal
Why is there a major error with the FA in CC_Anterior section (see attached image)?
