Hi FreeSurfer experts,

I have a doubt regarding the atlas coordinates that uses QDEC. In the power point titulated "fscoordinates" found in the FreeSurferWiki seems that the coordinates used are aligned with Talairach Atlas, but when you enter de coordinates provided by QDEC in a particular area (Right isthmus for example: -32 -29 26) in a Talairach client software ( http://www.talairach.org/client.html) , the area that it gives you is totally different:

Label at (-32, -29, 26) Left Cerebrum, Frontal Lobe, Sub-Gyral, White Matter, *

Do you know why this discrepancy is caused for?

Thank you in advance,
