Backwards incompatible changes:
AlignmentFile.header now returns an AlignmentHeader object. Use AlignmentFile.header.to_dict() to get the dictionary as previously. Most dictionary accessor methods (keys(), values(), __getitem__, …) have been implemented to ensure some level of backwards compatibility when only reading.
The rationale for this change is to have consistency between AlignmentFile and VariantFile.
AlignmentFile and FastaFile now raise IOError instead of OSError
Medium term we plan to have a 1.0 release. The pysam interface has grown over the years and the API is cluttered with deprecated names (Samfile, getrname(), gettid(), …). To work towards this, the next release (0.15.0) will yield DeprecationWarnings for any parts of the API that are considered obsolete and will not be in 1.0. Once 1.0 has been reached, we will use semantic versioning.
This release wraps htslib/samtools/bcftools versions 1.6.0 and contains a series of bugfixes.
- [#544] reading header from remote TabixFiles now works.
- [#531] add missing tag types H and A. A python float will now be added as ‘f’ type instead of ‘d’ type.
- [#543] use FastaFile instead of Fastafile in pileup.
- [#546] set is_modified flag in setAttribute so updated attributes are output.
- [#537] allow tabix index files to be created in a custom location.
- [#530] add get_index_statistics() method
Bugfix release to solve compilation issue due to missinge bcftools/config.h file.
This release wraps htslib/samtools/bcftools versions 1.5.0 and contains a series of bugfixes.
- [#473] A new FastxRecord class that can be instantiated from class and modified in-place. Replaces PersistentFastqProxy.
- [#521] In AligmentFile, Simplify file detection logic and allow remote index files
- Removed attempts to guess data and index file names; this is magic left to htslib.
- Removed file existence check prior to opening files with htslib
- Better error checking after opening files that raise the appropriate error (IOError for when errno is set, ValueError otherwise for backward compatibility).
- Report IO errors when loading an index by name.
- Allow remote indices (tested using S3 signed URLs).
- Document filepath_index and make it an alias for index_filename.
- Added a require_index parameter to AlignmentFile
- [#526] handle unset ref when creating new records
- [#513] fix bcf_translate to skip deleted FORMAT fields to avoid segfaults
- [#516] expose IO errors via IOError exceptions
- [#487] add tabix line_skip, remove ‘pileup’ preset
- add FastxRecord, replaces PersistentFastqProxy (still present for backwards compatibility)
- [#496] upgrade to htslib/samtools/bcftools versions 1.5
- add start/stop to AlignmentFile.fetch() to be consistent with VariantFile.fetch(). “end” is kept for backwards compatibility.
- [#512] add get_index_statistics() method to AlignmentFile.
In the next release we are plannig to separate the header information from AlignmentFile into a separate class AlignmentHeader. This layout is similar to VariantFile/VariantHeader. With this change we will ensure that an AlignedSegment record will be linked to a header so that chromosome names can be automatically translated from the numeric representation. As a consequence, the way new AlignedSegment records are created will need to change as the constructor requires a header:
header = pysam.AlignmentHeader( reference_names=["chr1", "chr2"], reference_lengths=[1000, 1000]) read = pysam.AlignedSegment(header)
This will affect all code that instantiates AlignedSegment objects directly. We have not yet merged to allow users to provide feed-back. The pull-request is here: https://github.com/pysam-developers/pysam/pull/518 Please comment on github.
Bugfix release to address two issues:
- Changes in 0.11.2.1 broke the GTF/GFF3 parser. Corrected and more tests have been added.
- [#479] Correct VariantRecord edge cases described in issue
Release to fix release tar-ball containing 0.11.1 pre-compiled C-files.
This release wraps htslib/samtools/bcfools versions 1.4.1 in response to a security fix in these libraries. Additionally the following issues have been fixed:
- [#452] add GFF3 support for tabix parsers
- [#461] Multiple fixes related to VariantRecordInfo and handling of INFO/END
- [#447] limit query name to 251 characters (only partially addresses issue)
VariantFile and related object fixes
- Restore VariantFile.__dealloc__
- Correct handling of bcf_str_missing in bcf_array_to_object and bcf_object_to_array

- VariantRecordInfo.__delitem__ now allows unset flags to be deleted without raising a KeyError
- Multiple other fixes for VariantRecordInfo methods
- INFO/END is now accessible only via VariantRecord.stop and VariantRecord.rlen. Even if present behind the scenes, it is no longer accessible via VariantRecordInfo.
- Add argument to issue a warning instead of an exception if input appears to be truncated
Other features and fixes:
- Make AlignmentFile __dealloc__ and close more stringent
- Add argument AlignmentFile to issue a warning instead of an exception if input appears to be truncated

This release implements further functionality in the VariantFile API and includes several bugfixes:
- treat special case -c option in samtools view outputs to stdout even if -o given, fixes #315
- permit reading BAM files with CSI index, closes #370
- raise Error if query name exceeds maximum length, fixes #373
- new method to compute hash value for AlignedSegment
- AlignmentFile, VariantFile and TabixFile all inherit from HTSFile
- Avoid segfault by detecting out of range reference_id and next_reference in AlignedSegment.tostring
- Issue #355: Implement streams using file descriptors for VariantFile
- upgrade to htslib 1.3.2
- fix compilation with musl libc
- Issue #316, #360: Rename all Cython modules to have lib as a prefix

- Many minor fixes and improvements to VariantFile and related objects
Please note that all internal cython extensions now have a lib prefix to facilitate linking against pysam extension modules. Any user cython extensions using cimport to import pysam definitions will need changes, for example:
This is a bugfix release addressing some installation problems in pysam 0.9.0, in particular:
- patch included htslib to work with older libcurl versions, fixes #262.
- do not require cython for python 3 install, fixes #260
- FastaFile does not accept filepath_index any more, see #270
- add AlignedSegment.get_cigar_stats method.
- py3 bugfix in VariantFile.subset_samples, fixes #272
- add missing sysconfig import, fixes #278
- do not redirect stdout, but instead write to a separately created file. This should resolve issues when pysam is used in notebooks or other environments that redirect stdout.
- wrap htslib-1.3.1, samtools-1.3.1 and bcftools-1.3.1
- use bgzf throughout instead of gzip
- allow specifying a fasta reference for CRAM file when opening for both read and write, fixes #280
The 0.9.0 release upgrades htslib to htslib 1.3 and numerous other enhancements and bugfixes. See below for a detailed list.
comes with additional capabilities for remote file access which depend
on the presence of optional system libraries. As a consequence, the
setup.py has become more complex. For an
overview, see Installing pysam. We have tested installation on
linux and OS X, but could not capture all variations. It is possible
that a 0.9.1 release might follow soon addressing installation issues.
VariantFile class provides access to
vcf and bcf formatted files. The class is certainly
usable and interface is reaching completion, but the API and the
functionality is subject to change.
Detailed release notes¶
upgrade to htslib 1.3
python 3 compatibility tested throughout.
added a first set of bcftools commands in the pysam.bcftools submodule.
samtools commands are now in the pysam.samtools module. For backwards compatibility they are still imported into the pysam namespace.
samtools/bcftools return stdout as a single (byte) string. As output can be binary (VCF.gz, BAM) this is necessary to ensure py2/py3 compatibility. To replicate the previous behaviour in py2.7, use:
get_tags() returns the tag type as a character, not an integer (#214)
TabixFile now raises ValueError on indices created by tabix <1.0 (#206)
improve OSX installation and develop mode
FastxIterator now handles empty sequences (#204)
TabixFile.isremote is not TabixFile.is_remote in line with AlignmentFile
AlignmentFile.count() has extra optional argument read_callback
- setup.py has been changed to:
- install a single builtin htslib library. Previously, each pysam module contained its own version. This reduces compilation time and code bloat.
- run configure for the builtin htslib library in order to detect optional libraries such as libcurl. Configure behaviour can be controlled by setting the environment variable HTSLIB_CONFIGURE_OPTIONS.
get_reference_sequence() now returns the reference sequence and not something looking like it. This bug had effects on get_aligned_pairs(with_seq=True), see #225. If you have relied on on get_aligned_pairs(with_seq=True) in pysam-0.8.4, please check your results.
improved autodetection of file formats in AlignmentFile and VariantFile.
This release contains numerous bugfixes and a first implementation of a pythonic interface to VCF/BCF files. Note that this code is still incomplete and preliminary, but does offer a nearly complete immutable Pythonic interface to VCF/BCF metadata and data with reading and writing capability.
Potential isses when upgrading from v0.8.3:
binary tags are now returned as python arrays
renamed several methods for pep8 compatibility, old names still retained for backwards compatibility, but should be considered deprecated.
- gettid() is now get_tid()
- getrname() is now get_reference_name()
- parseRegion() is now parse_region()
some methods have changed for pep8 compatibility without the old names being present:
- fromQualityString() is now qualitystring_to_array()
- toQualityString() is now qualities_to_qualitystring()
faidx now returns strings and not binary strings in py3.
The cython components have been broken up into smaller files with more specific content. This will affect users using the cython interfaces.
