I accessed the ABCC collection (Collection 3165) on NDA, and download the dMRI dataset with the method introduced at
https://github.com/ABCD-STUDY/nda-abcd-collection-3165, but I only downloaded dMRI data of 6701 subjects. I also check the
datastructure_manifest.txt access via NDA. There are only 6701 subject keys in that text file.
Why there is only 6701 subject for dMRI data? Based the
fastqc.txt, I get 9709 subject pass the qc.
(fastqc.ftq_complete == 1) & (fastqc.ftq_quality==1) & (fastqc.ftq_usable==1)
