Dear Ramesh, The subfield segmentations requires running recon-all -all first. But you can greatly speed up the execution with the openmp option. Also, you can try running two subjects simultaneously, but only for the recon-all -all part (the subfields use more memory and might crash).

Please see the attached image and give your suggestions. It took nearly 7 hrs 10 min. to complete hippo-subfield segmentation for one scan by using the command recon-all -i grp205_t1.nii -s grp205 -sd grp205 -all Started at Wed Apr 26 11:03:34 IST 2017 Ended at Wed Apr 26 17:17:35 IST 2017 #@#%# recon-all-run-time-hours 6.234 recon-all -s grp205 finished without error at Wed Apr 26 17:17:35 IST 2017 done Then for hipposubfield, recon-all -s grp205 -sd grp205 -hippocampal-subfields-T1 I want to run for 40 scans grp-1 20 scans and grp-2 20 scans. How to modify in the command. Since it is taking long time I want to run 10 scans n give rest again 10 scans. Can I do so? I am15.6 GiB ram, Intel® Core™ i7-4790 CPU @ 3.60GHz × 8 processor, GeForce GT 610/PCIe/SSE2 graphic card.It is octa core processor. Can I run 8 analysis simultaneously (in 8 separate terminal?). Your suggestion will be helpful to me to proceed further. Thanks RB
