Hello FS experts,
I am interested in utilizing the functional ROIs made by the Greicius lab
out of Stanford (found here<http://findlab.stanford.edu/functional_ROIs.html>).
However, these ROIs were made using FSL and the coordinate system for them
is not responding to simple resampling commands (such as mri_convert or
3dresample). The resulting file from utilizing these commands "works" in
the sense that it puts them in the proper orientation, but the ROIs are
still way out of whack, somehow.
Thus, I would like to try utilizing recon-all to get these ROIs (which
correspond to MNI152-2mm) into the standard space I'm utilizing
(Freesurfer-defined MNI305, based on the subjects' talairach.m3z file).
However, I have no idea how to do this. Could I have some general guidance
on the steps and options for recon-all that would accomplish this?
I have some additional information about the ROIs below.
*This is the 3dinfo output for the ROIs (in this case, anterior-salience)*
Template Space: TLRC
Dataset Type: Anat Bucket (-abuc)
Byte Order: LSB_FIRST {assumed} [this CPU native = LSB_FIRST]
Storage Mode: NIFTI
Storage Space: 3,610,516 (3.6 million [mega]) bytes
Geometry String: "MATRIX(2,0,0,-90,0,-2,0,126,0,0,2,-72):91,109,91"
Data Axes Tilt: Plumb
Data Axes Orientation:
first (x) = Right-to-Left
second (y) = Posterior-to-Anterior
third (z) = Inferior-to-Superior [-orient RPI]
R-to-L extent: -90.000 [R] -to- 90.000 [L] -step- 2.000 mm [ 91
voxels]
A-to-P extent: -90.000 [A] -to- 126.000 [P] -step- 2.000 mm [109
voxels]
I-to-S extent: -72.000 [I] -to- 108.000 [S] -step- 2.000 mm [ 91
voxels]
Thanks!
