I don't think there is a command to do this. I'd probably do it in matlab. Info about the coordinates can be found here

Each mgz volume has a voxel-to-RAS matrix, if you invert that, and multiply your RAS you will get the column, row, slice from which you can extract the value

Hi,

Could you please let me know the command that takes say, ras coordinates (or a list of them) and a .mgz as input, and outputs the corresponding voxel values from the .mgz?

Thanks.
