Hi all,
I have run a searchlight MVPA analysis using the bids-pymvpa app. I have been able to successfully run the searchlight code, and it generates an .nii file with the appropriate name. When I open the file in fsl (or similar software), I see the following:
How is this image to be interpreted, as it does not appear to be in MNI space. Is this what the .nii file should look like? The mri_info appears to be what I would expect:
Type: nii
dimensions: 65 x 77 x 55
voxel sizes: 3.000000, 3.000000, 3.600000
type: FLOAT (3)
fov: 195.000
dof: 0
xstart: -97.5, xend: 97.5
ystart: -115.5, yend: 115.5
zstart: -99.0, zend: 99.0
TR: 6000.00 msec, TE: 0.00 msec, TI: 0.00 msec, flip angle: 0.00 degrees
nframes: 1
PhEncDir: UNKNOWN
FieldStrength: 0.000000
ras xform present
xform info: x_r = 1.0000, y_r = 0.0000, z_r = 0.0000, c_r = 1.5000
: x_a = 0.0000, y_a = 1.0000, z_a = 0.0000, c_a = -16.5000
: x_s = 0.0000, y_s = 0.0000, z_s = 1.0000, c_s = 21.0000
Orientation : RAS
Primary Slice Direction: axial
voxel to ras transform:
3.0000 0.0000 0.0000 -96.0000
0.0000 3.0000 0.0000 -132.0000
0.0000 0.0000 3.6000 -78.0000
0.0000 0.0000 0.0000 1.0000
voxel-to-ras determinant 32.4
ras to voxel transform:
0.3333 0.0000 0.0000 32.0000
0.0000 0.3333 0.0000 44.0000
0.0000 0.0000 0.2778 21.6667
0.0000 0.0000 0.0000 1.0000
I would appreciate any suggestions.
Thank you very much,
