Hello,
I am viewing bam files in IGV and have a question. These bam files are generated from whole genome paired-end sequencing performed on human genomic DNA using Illumina instrument.
Attached IGV screenshot shows bam files aligned to human reference genome, alignment viewed as "pairs" and alignment colored by "insert size and pair orientation". As far as I know, green colored reads are indicative of tandem duplication whereas red colored reads are indicative of a deletion. But I don't know what it means when both red and green reads are present at the same genomic location (as shown in the attached screenshot)? Can anyone please help me understand this? Thanks!

Differential Expression and Data Visualization: Recommended Tools for Next-Level Sequencing Analysis
After covering QC and alignment tools in the first segment and variant analysis and genome assembly in the second segment, we’re wrapping up with a discussion about tools for differential gene expression analysis and data visualization. In this article, we include recommendations from the following experts: Dr. Mark Ziemann, Senior Lecturer in Biotechnology and Bioinformatics, Deakin University; Dr. Medhat Mahmoud Postdoctoral Research Fellow at Baylor College of Medicine;...05-23-2023, 12:26 PM -
Continuing from our previous article, we share variant analysis and genome assembly tools recommended by our experts Dr. Medhat Mahmoud, Postdoctoral Research Fellow at Baylor College of Medicine, and Dr. Ming "Tommy" Tang, Director of Computational Biology at Immunitas and author of From Cell Line to Command Line.

With new tools and computational resources being released regularly, it can be hard to determine which are best suited for the analysis process and which older tools continue to be maintained. In an effort to assist the sequencing community, we interviewed three highly skilled bioinformaticians about their recommended tools for several important analysis applications.
