Question

Question Posted 05/25/16:
When I extract the ADNI_cluster_01_forward_757LONI data. I found that the column where suppose to figure out the phenotype of the sample are all with value of -9.

How could I know each sample was affected by AD or not?

Thank you

That column was coded as missing because each person can use different coding scheme. So, please look at DXSUM_PDXCONV_ADNIALL.csv to know diagnosis of each individual at each visit.
