Re: [HCP-Users] Dense Connectome Time Courses

Correct on the mapping to the group ICA components. The order in the concatenated time series file is: REST1_LR REST1_RL REST2_LR REST2_RL Note that, in case it matters to you, the LR scan does NOT necessarily precede the RL scan temporally within each scan session.  However, the "REST1" scans should always be acquired in the same session, and the "REST2" scans acquired in a different session. cheers, -MH --  Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO  63110 Email: mha...@wustl.edu From: <Nomi>, Jason <jxn...@miami.edu> Date: Wednesday, March 4, 2015 9:20 AM To: "hcp-users@humanconnectome.org" <hcp-users@humanconnectome.org> Subject: [HCP-Users] Dense Connectome Time Courses Dear HCP Experts, I have a question regarding the text files found in the dense connectome release.  Are the columns found in the text files for the node time courses ordered in the same way as the melodic_IC_sum.nii.gz file?  That is, I assume that column 1 in the text file represents the time course for component 0 in the melodic file, column 2 = component 1, column 3 = component 2, etc, etc.  Also, for the 4800 time points listed in the text file, how does the ordering of the resting state acquisition scans go?  I know that there are four 15 minute resting state scans (1200 volumes each), 2 L-R and 2 R-L acquired.  But, how are they ordered in the text file? Are the first 2400 volumes L-R and R-L?  Or, are the first 2400 volumes both L-R, or both R-L? I would like to cut the file in half for an analysis (30 minute resting state scan) but want to ensure that I use a counterbalanced L-R and R-L acquisition parameter.   Thank you for the help - Jason ​ _______________________________________________ HCP-Users mailing list 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.
