Were they all collected at the same site? If not, I'd expect this to make some difference.

Diffusion isn’t affected by this, just fMRI because diffusion was processed with the same recon version (old scans were reprocessed). Peace, Matt.

By version number, do you mean the "acquisition" - that is, the Q#? So you expect the fMRI to be more different across acquisitions than the diffusion? Do you recall at which acquisition the image reconstruction version change occurred?

Diffusion data were retroreconned (and so all data have the same version), but fMRI raw data had not been saved and could not be retroreconned. We advise using a covariate of no interest for version number. Peace, Matt.

I'm wondering how the different acquisitions (ie Q1 Q2 etc) and releases would affect comparison across all SCs for example. Was data collected at different sites for example? - which may affect comparison across acquisitions. See below info pasted from behaviour spreadsheet. Do I understand correctly the "Release" column is when subjects were first released. but if i am getting all data from the S900, then I shouldn't care about this first release? Thanks, Joelle Subject Release Acquisition 100004 S900 Q06 100206 S900 Q11 100307 Q1 Q01 100408 Q3 Q03 100610 S900 Q08 101006 S500 Q06 101107 S500 Q06 101309 S500 Q06 101410 S500 Q06 101612 S900 Q11 101915 Q3 Q04 _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org<mailto:HCP-Users@humanconnectome.org> http://lists.humanconnectome.org/mailman/listinfo/hcp-users ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
