The CSF Biomarker dataset for ADNI GO and ADNI 2 subjects was replaced. The updated file is now available from the DOWNLOAD section of the ADNI archive. The dataset is named UPENN – CSF Biomarkers [ADNI GO/2]. The University of Pennsylvania also provided the accompanying methods and CSF report, which can be downloaded under the links UPENN – CSF Biomarkers Methods [ADNI GO/2] (PDF) and UPENN – ADNI GO/2 CSF Report (PDF).
