Thanks Donal, by deactivation the interpolation we float numbers get to integer one. But I still have the problem with using the labelconvert.  
Since I would like to have the structural connectivity for HCP by using the AAL116, I have followed all the t steps like Takafomai in [Problems with AAL parcellation](https://community.mrtrix.org/t/problems-with-aal-parcellation/567/6), except using 12 degrees of freedom for T1 to MNI and nearest neighborhood interpolation method, but still encountering the error of unexpected value. The result of the parcellation is tested over having the Negative values or any float numbers which both were rejected by using Matlab.  
Please note that for the input image I used the T1w\_acpc\_dc\_restore\_brain.nii which is available in HCP for each subject.  
Thanks
