Usage

This program is now part of the main jvarkit tool. See jvarkit for compiling.

Usage: java -jar dist/jvarkit.jar bamslicebed  [options] Files

Usage: bamslicebed [options] Files
  Options:
    --attributes
      Leep the following attributes (separated by spaces/comma/semicolon)
      Default: <empty string>
    --bamcompression
      Compression Level. 0: no compression. 9: max compression;
      Default: 5
  * -B, --bed, --pcr
      Regions containing non-overlapping PCR fragments. A source of intervals. 
      The following suffixes are recognized: vcf, vcf.gz bed, bed.gz, gtf, 
      gff, gff.gz, gtf.gz.Otherwise it could be an empty string (no interval) 
      or a list of plain interval separated by '[ \t\n;,]'
      Default: (unspecified)
    --clip
      Do not remove the bases but soft clip them.
      Default: false
    -h, --help
      print help and exit

      Output file. Optional . Default: stdout
    -R, --reference
      Indexed fasta Reference file. This file must be indexed with samtools 
      faidx and with picard/gatk CreateSequenceDictionary or samtools dict
    --regions
      Limit analysis to this interval. A source of intervals. The following 
      suffixes are recognized: vcf, vcf.gz bed, bed.gz, gtf, gff, gff.gz, 
      gtf.gz.Otherwise it could be an empty string (no interval) or a list of 
      plain interval separated by '[ \t\n;,]'
    --samoutputformat
      Sam output format.
      Default: SAM
      Possible Values: [BAM, SAM, CRAM]

• (2021) samtools ampliconclip - clip reads using a BED file http://www.htslib.org/doc/samtools-ampliconclip.html

Input/Output

input is a bam

output is a bam

name of the BED record is appended to the original read name/

unmapped reads, reads without cigar or reads that don’t overlap any BED record are discarded

MAPQ is set to 255

reads are converted to singled end

optional args are not filled

bounding bases with cigar string without cigar operator M/X/= are discarded.
