Thanks a lot for your email, Saskia. Does this happen for more than one subject? Can you reproduce the error? Cheers, /E

External Email - Use Caution
Dear FreeSurfer Developers,
I am attempting to run the longitudinal hippocampal subfields segmentation, using the development version of FreeSurfer. 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):

Error using kvlGEMSMatlab

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?
