It looks like the released HCP task fMRI data were produced using an older version of the Task analysis pipeline that does not automatically collate the beta maps into a labeled and easy to use dscalar file. The beta maps will be in these files:
${StudyFolder}/${Subject}/MNINonLinear/Results/${fMRIName}/${fMRIName}_hp200_s2_level2_MSMAll.feat/GrayordinatesStats/cope${i}.feat/cope1.dtseries.nii where ${i} = 1 to N contrasts Peace, Matt.

But why there is only one pe1 file with only one volume in it? For the contrast like, story > math I would expect to find two beta images, one for the "story" and one for the "math". In addition, the pe1.dtseries.nii maps are very correlated with tstat1.dtseries.nii (R>0.85) and there is similar correlation for all contrasts of the same task/subject.

In the cope* subfolders I can find the outputs of the contrast calculation, e.g., Zstat1.dtseries.nii. However, I do not see beta estimates for each regressor. Do I miss something or they are just not included in the analyzed archive. If the latter is correct, should I download non-analyzed data and run the analysis myself? What is the simplest way to to that? The only instructions that I found are from the last year course, and I am not sure how valid they are: https://www.humanconnectome.org/courses/2015/exploring-the-human-connectome.php https://wustl.box.com/shared/static/0vcsqc0yg3ncqmirryyxpgsiqhxww659.pdf Probably someone can post more recent instructions from the last month course.
