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
