variant pileup for sample 16 reads mapping

Paired end reads from sample 16 genomic sequencing were mapped on Arabis alpina contigs with BWA. Variant pileup was obtanied with samtools from bam file.将样本16基因组测序所得的双端测序读段（Paired end reads），使用BWA比对至高山南芥（Arabis alpina）的重叠群（contigs）。随后借助SAMtools从生成的BAM文件中提取变异堆读（variant pileup）数据。
