The subject-specific parcel timeseries were provided in a single text file for each model order with 4800 time points each. I am trying to figure out if time points 2401-3600 from those text files always correspond to the LR session from Day 2, or if they correspond to the RL session from Day 2 for the handful of subjects collected before 1 October 2012 and the LR session from Day 2 for everyone else. I just want to make sure that I label everything correctly.
I hope this clarifies my question. Thanks again for your help. -mb On Tue, Nov 24, 2015, 19:29 Glasser, Matthew <glass...@wustl.edu> wrote: > I’m still not following why it matters. > > Peace, > > Matt. > > From: Mary Beth <m...@jhmi.edu> > Date: Tuesday, November 24, 2015 at 6:18 PM > To: Matt Glasser <glass...@wustl.edu>, "hcp-users@humanconnectome.org" < > hcp-users@humanconnectome.org> > Subject: Re: [HCP-Users] phase encoding and group ICA > > I just want to make sure I'm comparing apples to apples when I use the > subject-specific timeseries. > > best, > mb > > On Tue, Nov 24, 2015 at 7:11 PM Glasser, Matthew <glass...@wustl.edu> > wrote: > >> Why does the order of the individual subject sessions matter for group >> ICA or PTNs? >> >> Peace, >> >> Matt. >> >> From: <hcp-users-boun...@humanconnectome.org> on behalf of Mary Beth < >> m...@jhmi.edu> >> Date: Tuesday, November 24, 2015 at 5:59 PM >> To: "hcp-users@humanconnectome.org" <hcp-users@humanconnectome.org> >> Subject: [HCP-Users] phase encoding and group ICA >> >> Hi all, >> >> According to this page >> http://www.humanconnectome.org/documentation/Q1/data-in-this-release.html, >> prior to 1 October 2012, the first resting state session of each visit was >> acquired with RL phase encoding, and the second session was acquired with >> LR phase encoding (RL/LR).
