This works perfect for subjects with multiple data time points, but I get the following error for subjects for which I have a single data time point (see attachment for the error log): ******************* Global iteration 2 ******************* ***** Estimating subject-specific atlas ***** Error using kvlGEMSMatlab /autofs/space/panamint_005/users/iglesias/software/freesurfer/GEMS2/Matlab/kvlMatlabObjectArray.cxx:82: itk::ERROR: MatlabObjectArray(0x7f8686741c40): Trying to access non-existing object (25) Error in kvlGetOptimizer (line 11) Error in SegmentSubfieldsT1Longitudinal (line 1155) Is it possible to run this longitudinal module on subjects with a single time point? Any thoughts on how to troubleshoot this? FreeSurfer version: freesurfer-Linux-centos7_x86_64-dev-20180118-d073f7e Platform: CentOS Linux 7 (Core) Uname -a: Linux mentat003.dccn.nl 3.10.0-693.17.1.el7.x86_64 #1 SMP Thu Jan 25 20:13:58 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Thanks for your help!
