Dear dHCP team,
I am trying to perform a longitudinal analysis of early brain development using dHCP data. While checking the Release 2 participant metadata, I noticed that some participants have a second imaging session listed, but I could not locate some of them in the released datasets (either Release 2 or Release 3).
For example, the following resting-state fMRI sessions are listed in the Release 2 participant information file, but I could not locate them in the released datasets:
-
sub-CC00370XX08_ses-205500
-
sub-CC00413XX09_ses-188400
-
sub-CC00309BN12_ses-204400
-
sub-CC00789XX23_ses-170000
-
sub-CC00639XX21_ses-166600
Could you please clarify whether these second imaging sessions are available to researchers and whether there is a procedure for requesting access to them?
My main interest is conducting longitudinal analyses within a specific developmental age range, so access to these fMRI sessions would be valuable for my research.
Thank you very much for your help.
Best regards,
Roxana
