Hello All,
I am planning to run the longitudinal stream on my data set and I have a few questions:
1) When I run the data cross sectionally using "recon-all -all" should I specify all my subject's T1 volumes (using the -file1.nii -1file2.nii) or can I run each of my subject's T1 volumes individually through recon-all? My understanding is that some motion correction will occur if I specify more than one T1 which may alter the results versus if I specify one T1?
2) What input files should I use to create my base templates? Are the input files the norm.mgz files from each subject?
Thank you in advance for your help!
Best, Tamara
Hi Tamara
1. Run each timepoint through the cross-sectional stream separately.
2. recon-all will figure out what files to use when you tell it to create the base.
