hmmm, that is strange. Can you tar and gzip the entire subject dir then upload it to our ftp site?

OK yes this is a problem with the main recon-all stream. It’d have been a miracle for the subfield module to recover from that…
At this point, I’ll defer to Doug / Bruce.
Cheers,

Dear Eugenio,
attached you’ll find the picture. Looks as though the left hippocampus has erroneously been attributed to gray matter.
Cheers, Angelika

Dear Angelika,
Can you please send us a screenshot of the inaccurate T1 segmentation?
Cheers,

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
