Samtools – [main_samview] fail to read the header 1 Hi everyone, I’m attempting to convert a SAM file to a BAM file using the following command: samtools view -S -b test.sam > test.bam However, I’m getting the error [main_samview] fail to read the header (see figure). The figure attached shows…

bamdst gives error “EOF marker is absent. The input is probably truncated.” 0 I created a set of bam files from Poolseq data using bwa -aln, and all of the output files gave the following error when I ran bamdst to get summary statistics on read depth: “EOF marker is…

Error in merged bam files 0 Hello I am trying to merge unmapped and mapped bam files. I merged the bam files using the picard tool (gatk.broadinstitute.org/hc/en-us/articles/360036883871-MergeBamAlignment-Picard). I checked the merged bam using ValidateSamFile command (gatk.broadinstitute.org/hc/en-us/articles/360036854731-ValidateSamFile-Picard-) and it showed the below errors: Error Type Count ERROR:MATES_ARE_SAME_END 5496 ERROR:MISMATCH_FLAG_MATE_NEG_STRAND 5478 ERROR:MISMATCH_MATE_CIGAR_STRING…

Thinking about launching a SAM program or purchasing a new SAM tool? Learn how to avoid the top 5 common mistakes that buyers encounter when implementing a SAM tool. Software Asset Management was introduced to me many years ago when a dear…

There is a common misconception that Software Asset Management (SAM) tools can completely mitigate your risk of a costly and disruptive audit. In fact, studies show zero correlation between having a SAM tool in place and whether you will end up paying audit fees or how much you will ultimately…

Validation in new sample 0 Hi Sam, I am trying to validate in a new sample a PRS I conceived by PRSice. I would like to ask if using snp_prs function (bigsnpr package in R) is a good way for that or should I use another tool or method. Best…

Segemehl -D option doesnt work for allowing differences 0 I am trying to map short some specific short reads (19~20nts) against long reads of a fasta file (F1.fasta). I used Segemehl tool and indexed the F1.fasta file (long reads) and then used the command line below to perform the alignment:…

How to extract all sequences mapped to a transcript from Kallisto output 0 I ran Kallisto with the –pseudobam option. How do I extract all the short reads that are mapped to a single transcript (e.g. ENST00000367969.8)? As a person without any previous SAM/BAM experience, I tried the following things…

I was just doing something similar about a week ago. You may be able to accomplish this using the GenomicFeatures R package. First load up the following in R: library(GenomicFeatures) library(GenomicRanges) library(rtracklayer) Then you will need to get the chromosome sizes file, which you can generate with directions from this…
