Hello,

i am using the hippocampal subfield segmentation. I am looking at the results in [lr]h.hippoSfVolumes-T1.v10.txt. I saw the following in the FAQs and was unsure of what the units were then in the .txt file. Does the .txt file give units in mm^3?

The sum of the number of voxels of a given structure multiplied by the volume of a voxel is not equal to the volume reported in [lr]h.hippoSfVolumes*.txt.

This is because the volumes are computed upon a soft segmentation, rather than the discrete labels in [lr]h.hippoSfLabels*.mgz. This is the same that happens with the main recon-all stream: if you compute volumes by counting voxels in aseg.mgz, you don't get the values reported in aseg.stats.

Thank you,

Anna
