EXAMPLES

       snp_store   -mc   2   -it  2  exampleGenome.fa  exampleReads.gff  -o  exampleSNPs.vcf  -id
       exampleIndels.gff
              Call SNPs and  indels  of  a  low-coverage  example  (minimum  coverage  and  indel
              threshold were reduced to 2).

       snp_store  -re  -mc  2  -it  2  exampleGenome.fa  exampleReads.gff  -o exampleSNPs.vcf -id
       exampleIndels.gff
              Computes a realignment before variant calling. Now, the two 1bp  insertions  should
              have been merged into one 2bp insertion.
