Module `Biocaml_ez.Bam`Source

include module type of struct include Biocaml_unix.Bam end

A BAM file is composed of a header and a list of alignment records. The datatypes used in this module are based on those defined in the Sam module.

Sourcemodule Header = Biocaml_unix.Bam.Header

BAM header files contain a plain text SAM header, plus additional information related to the encoding of the file.

Sourcetype alignment = Biocaml_unix.Sam.alignment

Sourcemodule Alignment0 = Biocaml_unix.Bam.Alignment0

Representation of partially parsed alignments. When traversing a BAM file for a specific calculation, it may be that only some fields of the alignment records are actually used. In that case, it can be significantly faster to use this representation. As a downside, some encoding errors in the BAM file can go unnoticed.

Source

val read0 : 
  Core_kernel.In_channel.t ->
  (Header.t * Alignment0.t Core_kernel.Or_error.t Stream.t)
    Core_kernel.Or_error.t

read0 ic returns an error if a valid header cannot be read from ic or a pair containing a header and a stream of possibly errored (partially parsed) alignments. The stream stops after the first error.

Source

val write0 : 
  Header.t ->
  Alignment0.t Stream.t ->
  Core_kernel.Out_channel.t ->
  unit

write0 h xs oc writes the header h and (partially parsed) alignments xs to oc.

Source

val read : 
  Core_kernel.In_channel.t ->
  (Header.t * alignment Core_kernel.Or_error.t Stream.t) Core_kernel.Or_error.t

read ic returns an error if a valid header cannot be read from ic or a pair containing a header and a stream of possibly errored alignments. The stream stops after the first error.

Source

val write : 
  Header.t ->
  alignment Stream.t ->
  Core_kernel.Out_channel.t ->
  unit Core_kernel.Or_error.t

write h xs oc writes the header h and the alignments xs to oc.
