Table 2. This table shows the samples, which were mixed and sequenced together.

RUN	SAMPLE	TYPE	BRAIN REGION	INDEX
Altogether 17 pooled libraries were run; three (or two, in two cases: “run 9” and “run 17”) barcoded libraries were sequenced in a HiSeq 2000 lane. The type of the samples (suicide or control), as well as their origin (brain tissue region) were the same in the pools, with the exception of “run 13”, in which a sample from cerebellar cortex was mixed with two samples from somatomotor cortex region. The following SureSelectXT 6-bp indexing primers were used: index 4 - TGACCA; index 6 – GCCAAT; index 12 – CTTGTA.
