structural variant vcf file comparison
... Hi, I have six vcf files (cases vs control) that contain structural variants with variable length from nanopore sequence run. These vcf files were generated using NGMLR aligner followed by sniffle. What is the best way/tool to compare these files? Thanks Tarek ...

Using one bam file with huge coverage, How to generate several bam files with different coverage
... Hi, I have a bam file includes a single gene sequence with huge coverage (> 5000X) from which I want to call snps. I have several snps previously identified in my sample which I am going to use as control to test my pipeline. From my original bam file , I want to generate some bam files with dif ...
