Hi Jingwei, The issue you found is limited to the "Noise_Comp" variable, which is the NIH Toolbox Words in Noise (WIN) Computed score. NIH Toolbox changed the WIN test from v1 to v2 during the HCP data collection and only the v1 scores have been correctly released in ConnectomeDB. Those subjects that have -99, and many of of those with no score were tested with WIN v2. Originally, our internal database was keeping the v1 and v2 scores separate so that we could determine comparability b/w v1 and v2. NIH Toolbox has verified that the v1 and v2 scoring has been normed to be directly comparable, so we need to combine the v1/v2 scores into a single variable so all scores are released.
Therefore, we need to fix the released scores for the "Noise_Comp" variable -- we will document the issue on the HCP Issues and Planned Fixes wiki page and email the list when we release the fix.

We want to ask whether this number means erroneous data. Are those subjects usable for this behavior? If -99 means error and is not usable, is there any other behavior that has similiar issue that we need to do a postprocessing?
