Hi HCP Users,
Our center recently began using the UMinn 3T PRISMA protocols and I noticed some minor distortion in the vmPFC region. I was planning on applying FSL's topup to try and correct for this but when I was making the phase encoding text file I noticed in the protocol that both the DWI_dir98_AP and DWI_dir98_PA seem to use A >> P phase encoding. http://lifespan.humanconnectome.org/data/LSCMRR_3T_printout_2014.08.15.pdf Does that mean that both are AP? I remember seeing the same when we first started the AP sequence on the scanner and that doesn't seem correct. I also noticed the only differences in the the b-tables were for the vector values for b0's in AP vs PA, with the rest the same. May I ask why this is or if it has anything to do with the phase encoding? -- *Thomas DeRamus* UAB Department of Psychology, Behavioral Neuroscience Graduate Research Trainee Civitan International Research Center 1719 6th Ave S, Suite 235J, Birmingham, AL 35233 *Phone*: 205-934-0971 *Email:* [email protected], [email protected] _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
