samtools-depad - convert padded BAM to unpadded BAM
Contents
Description
Converts a BAM aligned against a padded reference to a BAM aligned against the depadded reference. The
padded reference may contain verbatim "*" bases in it, but "*" bases are also counted in the reference
numbering. This means that a sequence base-call aligned against a reference "*" is considered to be a
cigar match ("M" or "X") operator (if the base-call is "A", "C", "G" or "T"). After depadding the
reference "*" bases are deleted and such aligned sequence base-calls become insertions. Similarly
transformations apply for deletions and padding cigar operations.
Name
samtools-depad - convert padded BAM to unpadded BAM
Options
-S Ignored for compatibility with previous samtools versions. Previously this option was required if
input was in SAM format, but now the correct format is automatically detected by examining the
first few characters of input.
-s Output in SAM format. The default is BAM.
-C Output in CRAM format. The default is BAM.
-u Do not compress the output. Applies to either BAM or CRAM output format.
-1 Enable fastest compression level. Only works for BAM or CRAM output.
-TFILE
Provides the padded reference file. Note that without this the @SQ line lengths will be
incorrect, so for most use cases this option will be considered as mandatory.
-oFILE
Specifies the output filename. By default output is sent to stdout.
--no-PG
Do not add a @PG line to the header of the output file.
