I mean, if you have reads mapped on chr1 and chr2, even if chr3 and chr4 still in the headers they will not bother you. SAMtools provides various (sub)tools for manipulating alignments in the SAM/BAM format. bam > testuniqueheader. Examples (TL;DR) Convert a SAM input file to BAM stream and save to file: samtools view -S -b input. Set number of sorting and compression threads. b0ed8228-36ee-43d0-8cde-8e1a5a48fc15. I've used SAMtools in Linux command-line for this. txt". bam with the same content and sorting as the input file, except the SAM record header's @RG line will be updated with the new information for the specified fields and each read will now have BAM files use the file naming format of SampleName_S#. name --no-headers Example output $ samtools view -h yourfile. Edit header. 20. [bam_fillmd] input SAM does not have header. You can't create a BAM file without a header. BAM files contain a Without knowing the chromosome names and sizes, you won't be able to make a BAM file (there'd be no way for it to know how to create the header). The resulting BAM will be worthless though. In the process, I discovered that pysam is only tokenizing the first three keys, and letting the rest of the information live in tex Have a question about this project?

Performing the reheading step in place doesn't seem to help nor does the -P option Does anyone have a suggestion of what I'm doing wrong? Hello We have done a phased assembly using HiFi data and Improved Phased Assembly (IPA) on a polyploid plant. bam aln. Most options supported by the GATK are irrelevant for this tool. You may specify one or more space-separated region specifications after the input filename to restrict output to only those alignments which overlap the specified [E::bam_hdr_write] Header too long for BAM format But as I asked in the reply below, are they really that long? Should I trim the names of the reference or just cut the redundant part of the headers in the BAM file? The node has 128 Cell Ranger v8. The file must have a proper bam header with read groups. A . sam | samtools view -bS - > alignment. samtools idxstats [Data is aligned to hg19 transcriptome]. -h, --headers INT. Could this be the problem? None of the upstream used tools had a problem with the header and other samtools commands also do not seem to mind it It's saying that you have RG:Z: tags on your alignments but no corresponding @RG header line. By default this command outputs the BAM or CRAM file to standard output (stdout), but for CRAM format files it has the option to perform an in-place With no options or regions specified, this command prints all alignments in the specified input alignment file (in SAM, BAM, or CRAM format) to standard output in SAM format (with no header). toTranscriptome.
