Bam record in its native encoding along with virtual address.
Instances
| IsBamRec BamRaw Source # | |
Defined in Bio.Bam.Writer Methods pushBam :: BamRaw -> BgzfTokens -> BgzfTokens Source # unpackBamRec :: BamRaw -> BamRec Source # | |
bamRaw :: MonadThrow m => Int64 -> Bytes -> m BamRaw Source #
Smart constructor. Makes sure we got a at least a full record.
virt_offset :: BamRaw -> Int64 Source #
More convenient representation of a BAM record.
Invariant: Either b_qual == Nothing or
fmap V.length b_qual == Just (V.length b_seq).

Cigar line in BAM coding Bam encodes an operation and a length into a single integer, we keep those integers in an array.
Instances
| Eq Cigar Source # | |
| Ord Cigar Source # | |
| Show Cigar Source # | |
| Storable Cigar Source # | |
alignedLength :: Vector v Cigar => v Cigar -> Int Source #
Extracts the aligned length from a cigar line. This gives the length of an alignment as measured on the reference, which is different from the length on the query or the length of the alignment.
newtype Nucleotides Source #
A nucleotide base in an alignment. Experience says we're dealing with Ns and gaps all the type, so purity be damned, they are included as if they were real bases.
To allow Nucleotidess to be unpacked and incorporated into
containers, we choose to represent them the same way as the BAM file
format: as a 4 bit wide field. Gaps are encoded as 0 where they
make sense, N is 15. The contained Word8 is guaranteed to be
0..15.
Instances
data Vector_Nucs_half a Source #
A vector that packs two Nucleotides into one byte, just like Bam does.
Constructors
| Vector_Nucs_half !Int !Int !(ForeignPtr Word8) |
Instances
type Extensions = [(BamKey, Ext)] Source #
A collection of extension fields. A BamKey is actually two ASCII
characters.
Constructors
| Int Int | |
| Float Float | |
| Text Bytes | |
| Bin Bytes | |
| Char Word8 | |
| IntArr (Vector Int) | |
| FloatArr (Vector Float) |
deleteE :: BamKey -> Extensions -> Extensions Source #
Deletes all occurences of some extension field.
insertE :: BamKey -> Ext -> Extensions -> Extensions Source #
Blindly inserts an extension field. This can create duplicates (and there is no telling how other tools react to that).
updateE :: BamKey -> Ext -> Extensions -> Extensions Source #
Deletes all occurences of an extension field, then inserts it with
a new value. This is safer than insertE, but also more expensive.
adjustE :: (Ext -> Ext) -> BamKey -> Extensions -> Extensions Source #
Adjusts a named extension by applying a function.
isProperlyPaired :: BamRec -> Bool Source #
