That sounds right, the TAB.txt files and EV .txt files should contain the info Kristina is looking for. See the 3T Task fMRI scripts and protocol details section on p.45 of http://humanconnectome.org/storage/app/media/documentation/s1200/HCP_S1200_Release_Reference_Manual.pdf
for general info on these files. The definitions of the variables in these files can be found in the Ref Manual Appendix 6: http://humanconnectome.org/storage/app/media/documentation/s1200/HCP_S1200_Release_Appendix_VI.pdf Best, Jenn Jennifer Elam, Ph.D. Scientific Outreach, Human Connectome Project Washington University School of Medicine Department of Neuroscience, Box 8108 660 South Euclid Avenue St. Louis, MO 63110 314-362-9387<tel:314-362-9387> [email protected]<mailto:[email protected]> www.humanconnectome.org<http://www.humanconnectome.org/> ________________________________ From: Keith Jamison <[email protected]> Sent: Thursday, June 29, 2017 9:18:03 AM To: Kristina Meyer Cc: [email protected]; Elam, Jennifer; Burgess, Gregory Subject: Re: [HCP-Users] Behavioral performance data I wasn't involved in these specific experiments, but I THINK the info you're looking for is in the TAB files: ${StudyFolder}/${SubjectID}/MNINonLinear/Results/tfMRI_{TASK}_{RUN}/{TASK}_run*_TAB.txt There's a row for each event (along with rows for other things you'll have to ignore), and columns that seem to contain the reaction times For example: ${StudyFolder}/${SubjectID}/MNINonLinear/Results/tfMRI_WM_LR/WM_run2_TAB.txt has a column Stim.RT ${StudyFolder}/${SubjectID}/MNINonLinear/Results/tfMRI_GAMBLING_LR/GAMBLING_run2_TAB.txt has a column QuestionMark.RT I believe the GLM timing files in /EVs/ were all distilled from information in the _TAB.txt file. You can cross-reference these event rows with some of the .txt files in /EVs/ to help clarify event type, accuracy, etc. Jenn/Greg, does this sound right, and are these task-specific TAB files documented anywhere at the moment? -Keith On Thu, Jun 29, 2017 at 4:06 AM, Kristina Meyer <[email protected]<mailto:[email protected]>> wrote: Hello Jenn, dear everyone, thanks for your reply and your suggestions! Actually, averaged reaction times and accuracy rates are not exactly what I am looking for, however. What I meant is the performance in each single trial. Is it possible to acquire these data? Information about the response latency and accuracy for each trial per person? Any help would be greatly appreciated. We are planning to model individual differences, so for our purposes, this trial-wise behavioral information would be immensely helpful.

Per run (RL or LR) in-scanner reaction time (RT) and accuracy (ACC) measures are available in each subject's tfMRI data in a {TASK}_Stats.csv file in the run specific task directory : ${StudyFolder}/${SubjectID}/MNINonLinear/Results/tfMRI_{TASK}_{RUN}/EVs/{TASK}_Stats.csv Per subject average RT and ACC measures for task variables across runs are available in the open access behavioral CSV that you can download in ConnectomeDB from the HCP S1200 Project page : https://db.humanconnectome.org/data/projects/HCP_1200 or from the Subject dashboard accessible through the "Explore Subjects" option in the HCP 1200 Subjects section of the multiprojects page you see upon login. Descriptions of key variables used in these data are available in: http://humanconnectome.org/storage/app/media/documentation/s1200/HCP_S1200_Release_Appendix_VI.pdf Let us know if this isn't the info you are looking for.

So far, I was somehow unable find these data or clear information - maybe I missed it? Thanks a lot for any guidance on this.
