Hi, Marina-
This post describes how to do it with Surf2VolCoord:

Basically, you put your coordinate location into a text file ("x y z" values in one row), preferably using RAI DICOM coordinates, and then you can get the closest surface index (and the Euclidean distance between your coords and that point). It might also be a good idea to doublecheck things in SUMA.
Here is a set of SUMA-generated standard surfaces and parcellations for the MNI 152 brain, if you don't have it already:
