Hi everyone,

I already have the phenotyp key for ADHD-200 public dataset. But there are columns which don't appear in the phenotyp key list. The list of missing keys includes:
- QC_S1/2_REST
- QC_S1/2_ANAT

Also there are few variables (QC_Rest_1, Inattentive, Verbal IQ, ADHD Index, Medical status and QC_Anatomical_1  that present as value  (-999 and/or ). Does anyone knows what this value means?
Also the variable Handedness has as its values the leves 1, 0.91, 0.82 and 0.83. I can't understand it.

Please help me...
P.S: following this link http://fcon_1000.projects.nitrc.org/indi/adhd200/, at the bottom of the page in The "ADHD-200 Global Competition" section you can access to the phenotyp key that i said below.

Thanks in advance.
Sincerely,

Francisco
