Version 2.0.16

Released on February 25th 2016.

The following three webservice methods return a list of transcript identifiers for some query:

  • getTranscriptsRange
  • getTranscripts
  • getTranscriptsByGeneName

Previously they didn't work correctly for LRG transcripts (a bogus version was included and no transcript was selected) and RefSeq transcripts on mtDNA (no transcript was selected).

Additionally, the getTranscriptsMapping webservice method didn't return enough information to construct a complete transcript name. This is now reported in a new transcript field.

Finally, the getTranscriptsRange method now optionally includes version numbers with the boolean versions argument (default false).

  • Visualise protein change, also with alternative start (#72).
  • Translate alternative start to M, also in variant (#72).

Version 2.0.11

Released on August 6th 2015.

Version 2.0.10

Released on July 21st 2015.

  • Don't crash the position converter on transcript mappings containing no exons (#63).
  • Use the notation for an uncertain stop codon, e.g., p.(Gln730Profs*?) instead of p.(Gln730Profs*96) when a variant results in a frame shift or extension and we don't see a new stop codon in the RNA (#57).
  • Added Dog (Broad CanFam3.1/canFam3) assembly for position converter (#56).

Version 2.0.9

Released on July 9th 2015.

  • Discard incomplete genes in genbank reference files (#26).

Version 2.0.5

Released on December 16th 2014.

Version 2.0.4

Released on November 19th 2014.

  • Many string encoding related fixes. Summarizing, Mutalyzer should now be completely aware of input and output string encodings, in all interfaces. Internally, all strings are unicode strings. This comes with minor changes in the webservice definitions, which most clients will probably not notice (GitLab!25).
  • Don't crash on mail errors in the batch scheduler (GitLab#30).
  • Fix importing transcript mappings from UCSC database (GitLab#9).
  • Rename GRCh36 to NCBI36 (GitLab#8).
  • Updated all Python dependencies to their latest versions.

Version 2.0.3

Released on September 20th 2014.

  • Fix several error cases in LOVD2 view on the name checker.

Version 2.0.2

Released on October 9th 2014.

  • Fix incorrect GRCm38 chromosome accession number versions.
  • Fix crash in position converter batch jobs.
  • Upgrade the webservice library we use (Spyne, from 2.10.10 to 2.11.0). This potentially affects behaviour of both our SOAP and HTTP/RPC+JSON webservices, although our tests did not show any problems.

Version 2.0.1

Released on September 27th 2014.

  • Fix POST requests to the HTTP/RPC+JSON webservice. This was a regression from version 2.0.beta-33. Thanks to Ken Doig for reporting the issue.

Version 2.0.0

Released on September 26th 2014.

This release does not bring many new features, but comes with significant changes to the technical infrastructure. GitLab!6 tracks most of this.

Some highlights especially users of the webservices should be aware of:

  • HTTP/RPC+JSON webservice has changed response format (wrapper object removed). See below for an :ref:`example <changelog_200_example>`.
  • No more plain HTTP access, only redirects to HTTPS.
  • Many website entrypoints have changed URLs and form parameter names (the old ones have HTTP redirects).
  • Removed old redirects from paths starting with /2.0/.
  • In maintenance mode, all requests get a Service Temporarily Unavailable response with status code 503.

Other changes:

  • Upload a genbank file using the SOAP webservice (uploadGenBankLocalFile).
  • Do not cleanup the cache during request handling (GitLab#18).
  • Add GRCh38 (hg38) assembly (GitLab!20).
  • Move from nose to pytest for unit tests (GitLab!23).
  • Fix running Mutalyzer in a virtual environment and have an up-to-date requirements.txt for pip (GitLab!4).
  • Switch from TAL to Jinja2 (GitLab!3).
  • Refactor user interfaces (GitLab!5).
  • Move from configobj to Python module based config (GitLab!7).
  • Use SQLAlchemy as ORM (GitLab!8).
  • Use Redis for stat counters (GitLab!10).
  • Port website from to Flask (GitLab!11).
  • Isolated unit tests using fixtures and an in-memory database (GitLab!12).
  • Display announcement on website (GitLab!14).
  • Database migrations with Alembic (GitLab!15).
  • Update documentation and use Sphinx (GitLab!16).
  • Move to semantic versioning, starting with version 2.0.0 (GitLab!22).
  • Add 404 not found page.
  • Don't auto remove comma characters in syntax checker.
  • Add a dash (-) as an allowed character in the gene name.
  • Range, reverse complement range, and compound insertions/insertion-deletions.

The wrapper object has been removed from the HTTP/RPC+JSON webservice response format. As an example, consider an old response format for the checkSyntax method:

  "checkSyntaxResponse": {
    "checkSyntaxResult": {
      "valid": true,
      "messages": {
        "SoapMessage": []

The new response format is:

  "valid": true,
  "messages": []

Older versions

The first lines of code for Mutalyzer 2.0 were written July 28th 2009, and version 2.0.beta-8 was released on January 31st 2011. As far as Mutalyzer 1 is concerned, archaeology is not really our field of research.

You can’t perform that action at this time.
