- What's new ?
+ What's new in Jalview 2.10.0b1 ?
- Jalview 2.9.0b1 is a bug fix release for Jalview 2.9, which has been in development since December 2014. In addition
- to a multitude of bug fixes and minor improvements (both small, and
- rather big!), it also brings major new capabilities for codon-level
- analysis of protein alignments and the retrieval and manipulation of
- structural data.
For the patches since version 2.9 was release, see the
- Jalview 2.9.0b1 Release Notes.
+ Jalview 2.10.0b1 is a patch release for 2.10, the next major release
+ in the Jalview 2 series. Full details are in the Jalview 2.10b1 Release
+ Notes, but the highlights are below.
-
- Highlights in Jalview 2.9
- - Visualisation, editing and analysis of
- cDNA and Protein alignments
A new Split View window allows linked
- protein and nucleotide sequence alignments to be viewed, edited,
- and analysed as one.
cDNA alignments can also be
- reconstructed from protein alignments calculated by Jalview's web
- services, and update in response to edits in the amino acid view.
To
- start experimenting with cDNA/Protein analysis, jut drop a file
- containing cDNA sequences which code for proteins in an existing
- alignment, and Jalview will do the rest.
- - Enhanced Integration of UCSF Chimera
Jalview
- 2.9 provides full support for the use of Chimera to view 3D
- structures linked to alignment views in the Jalview Desktop. We've
- also included support for saving Chimera sessions in Jalview
- project files.
Jalview and Chimera communicate using local
- web server connections, which may cause firewall alerts on some
- systems, but has the advantage of allowing bidirectional
- communication. Communication between Jalview and Chimera is now
- much more responsive, and selected regions in Chimera are now
- shown as highlighted regions in the Jalview desktop.
- - Interactive querying of the PDBe
Jalview
- users can now browse and retrieve 3D structure data from the PDB
- via the PDBe
- Search API (Gutmanas
- et al 2014). Developed in collaboration with the PDBe group at
- EMBL-EBI, the interface allows both structured and free-text
- queries to be performed, and allows automatic selection of the
- most relevant structures for an alignment acording to a variety of
- criteria.
- - Improved support for RNA visualisation
Jalview
- 2.9 integrates the latest version of the VARNA RNA Viewer, and VARNA views
- can also now be stored in Jalview projects. We've also dealt with
- a number of lingering bugs in the VARNA/Jalview interface,
- including the loss of pseudoknots when RNA secondary structure is
- shown VARNA.
- - Protein Secondary Structure predictions
- with JPred4
Jalview includes a number of new features for
- working with secondary structure predictions from the JPred4
- server. These include new popup menu actions to automatically hide insertions and highlight
- mutations in an alignment with respect to a Reference
- Sequence. Jalview 2.9's new scrollable
- SVG HTML export was also developed specifically for the JPred4
- server.
+ - Drag and drop reinstated for the Jalview desktop on
+ Windows, Linux and older OSX systems.
+ - Problems loading local PDB files have been fixed
+ - Conservation shading can be disabled for PID and consensus
+ based colour scheme
+
+ Major highlights of the 2.10.0 Release
+
+ - Ensembl sequence fetcher
Annotated
+ Genes, transcripts and proteins can be retrieved via Jalview's new
+ Ensembl REST
+ client. Support for import of Ensembl data allows:
+
+ - Aligned locus view
Transcripts
+ retrieved for a gene identifier via the Ensembl or
+ EnsemblGenomes sequence databases are automatically aligned to
+ their reference genome, and introns hidden from the view.
+ - Sequence variant data
Jalview
+ propagates variant annotation on genomic regions onto
+ transcripts and protein products, complete with associated
+ metadata such as clinical significance.
+
+ - Ensembl and ENA 'show cross-references'
+ support
The Calculations menu's 'Show
+ cross-references' now offers Ensembl as well as EMBLCDS and
+ Uniprot when CDS/Protein mapping data is available for download or
+ display. This allows variant annotation to be added directly to an
+ alignment of UniProt sequences.
+ - Working with structures
+
+ - More accurate structure mappings
+ Jalview now utilises the PDBe's SIFTS database (at EMBL-EBI)
+ to match structures
+ to UniProt sequences, even for structures containing
+ multiple copies of a sequence.
+ - Import structures as mmCIF
Jalview
+ now downloads data from the EMBL-EBI's PDBe site as mmCIF. This allows very large
+ structures to be imported, such as the HIV virus capsid
+ assembly.
+ - Chimera users will need to upgrade to
+ 1.11.1
If you use Chimera to view structures
+ downloaded by Jalview 2.10, you will need to make sure you are
+ running the latest version of Chimera.
+
+ - UniProt Free Text Search
The new
+ search dialog for UniProt allows you to browse and retrieve
+ sequences with free-text search, or structured queries.
+ - Reference sequence alignment view
+ Jalview 2.9 introduced support for reference sequences. In 2.10,
+ when a reference sequence is defined for the alignment, the
+ alignment column ruler is now numbered according to the reference
+ sequence. The reference sequence for alignment views can also be
+ saved and restored from Jalview projects.
