Hi Jesper,
Thanks for your help.
According to your suggestions, I have figured it out as follows.
1. flirt -in con01_T1 -ref MNI152_T1_2mm -omat flirt_mat -out flirt_out
2. fnirt --ref=MNI152_T1_2mm --in=con01_T1 --aff=flirt_mat --cout= warp --iout=fnirt_out --config=T1_2_MNI152_2mm.cnf
3. invwarp --warp=warp --out=inverted_warp --ref=con01_T1
4. applywarp --ref= con01_T1 --in=ROI --warp=inverted_warp --out=ROI_in_T1
This is feasible to obtain an image, not a mm corrdinate.
I just don’t understand how to get the accurate (x,y,z) coordinate in the original image, which corresponds to the known (x’,y’,z’) coordinate in the reference image(both in ”mm coordinates”).
Would you please give me some suggestions?
