HI Xinyang, Yes, those in your list are definitely the Retest subjects. You'd probably want to use the first set if you are using other data for those subjects that was collected for the first (test) timepoint so that you don't introduce a possible systematic bias for the retest subjects.
Some subjects might not have all the data for all the different behavioral tests or imaging modalities for a wide variety of reasons. In general, we make the data we have available, even if incomplete.

So in this case, either set is ok to use, right? :) Please find the subID list of the DCCS task attached. Apart from that, there is also a subject (No.341935) with 2 trials and a subject (No.638049) with 27 trials.

Likely these subjects are HCP Retest subjects who went through the entire protocol twice (about 6 months or so between acquisitions, depending on the subject) and therefore have two sets of responses/imaging datasets.

We are looking at the HCP battery of behavioral measures. We found that in the recordings of individual performances, there are some participants who repeated the task for a second time. For example, in the Executive Function DCCS task (on manual page 183), there are 30 experimental trials apart from the practice part. However, the excel recording shows that some participants finished 60 trials. We would like to know what was the situation and does it mean the first round of measurement invalid? Thanks a lot.
