 **2.Parameter Setting**
 PAPA will ask users to input a set of parameters before starting analysis:
-**(1)****SNP-gene annotation file name**: Please input the storage path and name of SNP-gene annotation file. We provide a SNP-gene annotation file, named “SNPmap.txt” in PAPA package. “SNPmap.txt” contains 419,513 entries. In this file, SNPs are assigned to a gene, if they located within the gene or < 500 kb upstream or downstream of the gene. Users’ SNP-gene annotation files are also acceptable in PAPA. Please make your SNP-gene annotation files using following format:

+3.Output files
+PAPA will output two result files:
+[1]Pathway_result.txt: Pleiotropic pathway analysis result files. Each line of this file records a pathway and corresponding pleitropy analysis results, including normalized centered enrichment score (NCES) value and P value.
+   Example:
+   Pathway name    NCES    P value
+   BIOCARTA_ATM_PATHWAY    0.290   0.636
+   BIOCARTA_CELLCYCLE_PATHWAY  0.353   0.363
+   ....    
+   NCES can be used to measure the strength of association between pathways and disease phenotypes. In PAPA, circular permutation approach (Cabrera, et al., 2012, G3, 2, 1067-1075) is used to calculate the emperical P value of NCES  of each pathway. The pathways with P values < 0.05 are considered as significant pathway associated with disease phenotypes. 
+
+[2]Rplots.pdf: Plot of pleitropic pathway analysis results. In the generated figure, each point denotes a pathway. X-axis presents the total number of pathways analyzed by PAPA software. Y-axis shows –log10 (P values) calculated by PAPA.
