I am taking the course on coursera. For the final project we have to Identify DNA polymorphic sites.
I have completed most of the steps but when I try to filter my vcf file to find ins and del it returns 0 lines. When I do it separately no problem.
I tried every possible solutions, read forums, documentations and so on.
What I did I add filters with button and did not work, and I tried with combining two filtering criteria in a same line with & operator also did not work.
Any suggestions about this point?
