That does. Hopefully Steve can help with this. Peace,

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<mailto:glass...@wustl.edu>> wrote: I'm still not following why it matters. Peace, Matt.

After this date, the first visit continued to be acquired in the RL/LR order, but the second visit was acquired in the opposite order, with the LR acquisition followed by the RL acquisition (LR/RL). Here's my question: prior to group ICA and the generation of subject-specific sets of node timeseries in the August, 2014 "HCP500-PTN" (Parcellation+Timeseries+Netmats) data release, were the sessions for subjects acquired before 1 October 2012 reordered to match the order of sessions for subjects acquired after 1 October 2012?
