Dear Joshua, This is a bit of an empirical question. I’d totally run both on a few subjects and compare the results. If you do so: I would selfishly/greatly appreciate it if you shared your impressions with me :-) Cheers, /Eugenio

For the data we collect, we get a ADNI3 T2w SPC vNav.08 iso, ADNI3 Accelerated MPRAGE.01 iso (T1), and the ADNI3 HighRes Hippocampal sequence (T2w). We edit the ADNI3 T2w SPC and ADNI3 Accelerated MPRAGE T1 using freesurfer. My question is which T2w sequence should I use to run the command: segmentHA_T2.sh bert FILE_ADDITIONAL_SCAN ANALYSIS_ID USE_T1 [SUBJECTS_DIR]. The ASHS software uses the ADNI3 HighRes Hippocampal sequence so to compare the two outputs, it would be ideal to also use the HighRes Hippocampal sequence. Please let me know if you need additional information. Thanks, Joshua E. Pasaye, B.S.
