Hi FSL group,
I have ROIs in 2mm MNI standard space and I want to convert them TO 1mm MNI space. I used this command:
flirt -in lACC.nii.gz -ref /usr/share/data/fsl-mni152-templates/MNI152_T1_1mm_brain -applyxfm -out lACC_1mm
However, when I typed in fslinfo for both the original and new ROI, I saw that the dimensions were changed. Is this ok or should the dimensions be the same?
Below is the information:
>>fslinfo lACC-new.nii.gz
data_type INT16
dim1 91
dim2 109
dim3 91
dim4 1
datatype 4
pixdim1 2.0000000000
pixdim2 2.0000000000
pixdim3 2.0000000000
pixdim4 0.0000000000
cal_max 4.0000
cal_min 0.0000
file_type NIFTI-1+
>>fslinfo lACC_1mm.nii.gz
data_type FLOAT32
dim1 182
dim2 218
dim3 182
dim4 1
datatype 16
pixdim1 1.0000000000
pixdim2 1.0000000000
pixdim3 1.0000000000
pixdim4 0.0000000000
cal_max 0.0000
cal_min 0.0000
file_type NIFTI-1+
Best,
Dana
