Dear FSL experts,
I have run Melodic group ICA for the same rsfMRI data twice, but I had different results for highres2standard registration. For the 1st trial it worked well, but for the 2nd the final highres2standard.nii.gz was skewed like diamond shape.
I performed ICA from Melodic GUI. The parameters were the same except for the number of subjects. I confirmed that highres2standard_linear.nii.gz, highres2standard.mat, and standard2highres.mat files are identical between two trials, whereas highres2standard_warp.nii.gz and highres2standard.nii.gz are different. Thus I think the problem is in nonlinear registration.
I appreciate if anyone could explain the reason. I would like to attach the files but it exceed the maximum size.
Thanks in advance,
Jun
