External Email - Use Caution

Hi all,

I'm doing hippocampal subfields analysis with freesurfer 6.0 with T1 and high resolution T2 data from a 7T MRT. With at least one of my datasets Matlab throws an error during the hippocampal-subfields-T2 -pipeline:

Making Unknown map to reduced label 14 Computing hyperparameters for estimation of Gaussians of T2 data Error using | Inputs must have the same size.

Error in segmentSubjectT2_autoEstimateAlveusML (line 1064)

With other patients, the pipeline on the T2 images is correctly working without errors. I'm wondering what is causing this error and whether there is something I can do to avoid it?

As far as I can see, the only difference between the "error" dataset and the others is that hippocampal subfields-T1 is also not calculated correctly. It finishes without errors, but the final result does not cover the hippocampus correctly (probably due to a T1-hypointense cyst in the hippocampus of that patient).

Best regards,

Angelika
