Dear galaxy users, 
    We have done deep sequencing on some known genomic loci using Hiseq2000. I have already mapped the reads to the reference sequences by using Galaxy. In the next step, I want to find SNPs and calculate the SNP percentage within the reads. There are 500,000 to 1,000,000 reads per biological sample. Can I do it with galaxy? If not, is there other programs available in windows? Considering that I am not very familiar with programming. 

Thanks,
