    SAMtools pileup output

    Hi all,

    I have used SAMtools pileup in order to identify indels. According to this page, there should be 13 columns.

    My output has 15 columns, and most of the lines make sense, e.g.:

    Code:
    chr1	107591963	*	*/-TC	69	69	59	91	*	-TC	86	5	0	0	0
    I assumed that the sum of columns 11, 12, and 13 would equal column 8. This holds for most of the indels, but I noticed it doesn't hold for all.

    There are certain regions with very high read depths and which do not satisfy (c11+c12+c13)==c8. Example:

    Code:
    chr2	98507236	*	*/*	2652	0	28	7999	*	-T	1019	5	0	0	0
    chr2	98507238	*	*/*	2619	0	28	8001	*	-G	1022	1	1	1	964
    chr2	98507239	*	*/*	2800	0	28	8000	*	-A	1017	6	1	0	0
    chr2	98507245	*	*/*	2947	0	28	7990	*	-G	1022	2	0	0	0
    chr2	98507247	*	*/*	2990	0	29	7998	*	-C	1021	3	0	0	0
    chr2	98507249	*	*/*	3016	0	29	7992	*	-A	1023	1	0	0	0
    When I view this region in IGV (screenshot), it looks poorly mapped but definitely not read depths of ~10k.

    Any ideas on why this might be?

    Pileup is no longer in the new release, try using "mpileup" as you will have trouble be finding support.

      Advanced Sequencing Platforms Tackle Neuroscience’s Toughest Genomics Problems
      by SEQadmin2



      Genomics studies in neuroscience face a special challenge due to the brain’s complexity and scarcity of samples. Mapping changes in cell type and state using conventional next-generation sequencing methods remains challenging. Advances in technologies like single-cell sequencing, spatial transcriptomics, and long-read sequencing have opened the door to deeper studies of the brain and diseases like Alzheimer’s, amyotrophic lateral sclerosis (ALS), and schizophrenia.

      Cancer Drug Resistance: The Lingering Barrier to Rising Survival
      by SEQadmin2



      Cancer survival rates have significantly increased in the last few decades in the United States, reaching a combined 70% 5-year survival rate by 2021. Behind this number, there are years of research to find new therapies, drug targets, and early detection methods. But there is one core challenge that keeps slowing down these advances, and it’s about drug resistance.

      There is no single reason why many patients don’t respond to treatment as expected. Cancer is...
