Hello Sir, I'm using FreeSurfer through Virtual Box. I tried the below command for reslicing my volume according to a reference volume but the process gets stuck at " reading volume".
*mri_convert A.nii.gz A.resliced.nii.gz -rl B.nii.gz* A: Volume to be resampled / resliced B: Reference Volume Error message is being shown like below: mri_convert a.nii a.resliced.nii -rl b.nii $Id: mri_convert.c,v 1.179.2.7 2012/09/05 21:55:16 mreuter Exp $ reading from a.nii... -------------------------------------------------------------------------- ERROR: Invalid FreeSurfer license key found in license file /home/bibl04/Data_Home/Desktop/freesurfer/license.txt If you are outside the NMR-Martinos Center, go to http://surfer.nmr.mgh.harvard.edu to get a valid license file (it's free). If you are inside the NMR-Martinos Center, make sure to source the standard environment. Actually, I have two volumes, belong to the same subject. One volume is the ground truth which will be considered as standard for the second volume which is the processed one or the extracted brain. To perform a perfect comparison between both volumes, these must generate equal number of slices in order to compare the corresponding slide. But here there is problem with my volumes, that is while performing slicing Ground Truth volume is generating 360 slice and processed volume is generating 181 slides. So comparison can't take place in this way. What all I need is to do the resampling or generating the 181 slides from the Ground Truth as well. Best Regards, Gunjan
