Hi all, I've been trying to run the hippocampal subfield segmentation with T1 and T2 images, and haven't had much luck. I had previously run recon-all on all my scans in v5.3, but testing on one subject I re-ran recon-all with the additional T2 scan, and that seems to have run fine. However, when I try to run the subfield segmentation, I am getting errors. My command line is:
recon-all -s CRC040 -hippocampal-subfields-T1T2 CRC040/mri/T2.mgz CRC040T1T2 -no-isrunning but I have also tried: recon-all -s CRC040 -hippocampal-subfields-T1T2 CRC040/mri/orig/T2raw.mgz CRC040T1T2 -no-isrunning and: recon-all -s CRC040 -hippocampal-subfields-T1T2 ./CRC040.nii CRC040T1T2 -no-isrunning The error I am getting is: /Applications/freesurfer_v6/bin//mri_robust_register --mov /data/blinky/work/cassie/CRC/crcimage/sam_mprage/CRC040/mri/norm.mgz --maskmov /data/blinky/work/cassie/CRC/crcimage/sam_mprage/CRC040/tmp/hippoSF_T1T2_v10_CRC040T1T2_right//wholeBrainMask.mgz --dst /data/blinky/work/cassie/CRC/crcimage/sam_mprage/CRC040/mri/T2.mgz --lta /data/blinky/work/cassie/CRC/crcimage/sam_mprage/CRC040/mri/transforms/T1_to_CRC040T1T2.v10.lta --noinit --cost NMI -nosym >/dev/null: Signal 127 ERROR: cannot find transform file /data/blinky/work/cassie/CRC/crcimage/sam_mprage/CRC040/mri/transforms/T1_to_CRC040T1T2.v10.lta gunzip: can't stat: /data/blinky/work/cassie/CRC/crcimage/sam_mprage/CRC040/tmp/hippoSF_T1T2_v10_CRC040T1T2_right//T2resampledLikeT1.mgz (/data/blinky/work/cassie/CRC/crcimage/sam_mprage/CRC040/tmp/hippoSF_T1T2_v10_CRC040T1T2_right//T2resampledLikeT1.mgz.gz): No such file or directory ERROR: problem reading fname SWITCH expression must be a scalar or string constant.

The hippocampal pipeline runs fine without the T2 scan, however I am planning to use the subfield segmentation as a mask for some white matter tractography analysis in FSL, and the dimensions of the output are not close to my nifti files. I was hoping that using the T2 registration would help with this, but can't get it to work! Any help would be greatly appreciated. Kind regards, Cassie
