Venn diagram of overlapped candidate genes in NGS BA22 brain samples and SZGene. This diagram shows the heterogeneous variation of result with different quantitative tools. Candidate genes from Wu et al.(2012) were selected by TopHat+Cufflinks, whereas SCZCGs were selected by Bowtie 1+RSEM. There are 30 candidate genes appeared in both Wu et al. and SCZCGs. Only 2 candidate genes existed simultaneously in SZGene and NGS BA22 brain samples.
