Hi,
I have registered a patient’s MRI over the ColinN27 with mri_cvs_register and now i need convert an electrode (or voxel) coordinate from the subject’s space to the N27 space. I found an old post in the mailing list, but it did not work for me. The coords.txt file is just one line containing 10 10 10. What am i doing wrong?

Here are the commands i used and the results :
createMorph --out fullCSVmorph.tm3d --template /Volumes/Sector2/surfaces/TandonLang/TT_N27/mri/orig.mgz --subject /Volumes/Sector2/surfaces/TandonLang/TS076CD/mri/orig.mgz --in gcam /Volumes/Sector2/surfaces/TandonLang/TS076CD/TS076CD/csv/combined_toColin27_elreg_aseg.m3z
