Hi FreeSurfer experts, 

I preprocess my data with FreeSurfer v 6. 

After it I ran developmental version of freesurfer to get the hippocampus subfields ROI and volume. 

I get the following output:

# Hippocampal subfield volumes as created by segmentHA_T1.sh

1 1  0 618.413010 Hippocampal_tail

2 2  0 308.580548 subiculum-body

3 3  0 112.098146 CA1-body

4 4  0 146.657166 subiculum-head

5 5  0 202.046082 hippocampal-fissure

6 6  0 144.323840 presubiculum-head

7 7  0 513.572092 CA1-head

15 15  0 150.412851 CA4-head

16 16  0 150.002992 CA4-body

17 17  0 85.262570 fimbria

18 18  0 149.769932 CA3-head

19 19  0 61.819269 HATA

20 20  0 1333.761205 Whole_hippocampal_body

21 21  0 1748.804555 Whole_hippocampal_head

22 22  0 3700.978770 Whole_hippocampus

I can see in the hipposubfields.lh.T1.v21.stats and lh.hippoSfVolumes-T1.v21.txt files with separate information for the head and tail volumes of each subfield. 

May I know what is the file name containing the corresponding separate head and tail ROIs that were use to calculate the above mentioned volumes?

I can only find full subfield in all the ROI files.

Thank you.

Regards,

Naveed
