CLC Genomics Workbench 4.0.3
- Enhanced usability of GSEA analysis wizard: The "Remove duplicates" option is now a check box to switch on and off. Before, the choice of switching off was implicit by choosing Feature ID as the identifier. Now this is explicit using a check box.
- Improved performance rendering large tables, particularly those with html formatting.
- SNP and DIP detection previously ignored overlapping pairs. Now they count (as one read) if they fulfill the quality criteria (SNP detection). In cases where the two parts of the pair disagree, the pair does not count. We recommend running all SNP and DIP detections based on overlapping pairs data sets again (this would be the case if the minimum distance when mapping the reads is lower than two times the read length). There is no need to re-run mappings - just the SNP/DIP detection.
- ChIP-Seq: "nearest gene" reported not always right. This was the case for the last peak on each chromosome and also in cases where the order of the gene annotations in the reference file did not correspond to the order of the annotations on the actual sequence. We recommend running all ChIP-Seq Analyses again to get the correct reporting of nearest genes. There is no need to re-run the mappings.
- SNP Annotation Using BLAST failed with certain query sequences (the result could not be shown)
- Fixed crash of 454 import on certain Linux and Mac systems
- SOLiD import accepts read names with -P2 at the end
- Improved import of SAM/BAM files:
- Better support for files from SOLiD Bioscope
- Preliminary support for Complete Genomics files (The actual alignment is not represented completely - insertions that relates to a consensus sequence will be represented as unaligned ends in the imported mappings. This should be taken into account when looking for variations.)
- In the Sequencing Data Analysis-> Assemble Sequences to Reference, the conflict resolution was disabled when not including a reference sequence in the output.
- When importing sequences from Genbank files, mRNA annotations now prefer taking name after "locus_tag" rather than "product".
- Various minor bug fixes

- Problem regarding mapping of base-space data erroneously in color space. Under special circumstances, the user settings file contained the wrong default parameters and caused the mapping to be in color space rather than base space. We recommend running mappings performed in Genomics Workbench 4.0 again with Genomics Workbench 4.0.1.
- Fixed problem with SNP detection on large data sets suddenly running very slow.
- Scalability improvements in mapping and de-novo assembly with drastic improvements in performance

- Long reads assembly significantly faster
- No upper limit on number of reads in de novo assembly (there is still a limit regarding the size of the genome)
- New simple output option for de novo assembly: only generate consensus sequence instead of full contigs. At the last step of the de novo assembly wizard, you can now choose between "Full contigs" and "Simple contig sequences". The latter option will result in a sequence list with all the consensus sequences. This is much faster and less the demanding for the computer. You can always create full contigs later by running a reference assembly with the consensus sequences as references.

- Contig table shows latin and common name of reference sequences. This is beneficial if you perform a reference assembly against references from different species.
- Multiplexing - Process Tagged Sequences now has an option to filter away groups with few sequences. This is an advantage if you have very ambiguous barcode definitions where sequencing errors would lead to a lot of "false" groups. These groups can now be filtered because of their small size. (The option is called "Minimum number of sequences" and is found in the third step of the wizard.)
- Coverage info is now included when you export a table of contigs in ace format. (It contains a "Contig Tag" of type comment (a CT clause) containing a textual description of the coverage in the form "Average coverage: 14.65". )
- Coverage info is put into the description of consensus sequences extracted from a table of contigs (this means that if you export to fasta, this information will be included).
- Importing assemblies with more than one contig creates multi contig tables (ace and cas file import)
Improved user experience of processes
- Non-modal feedback from processes:
- When there is a message (e.g. from a BLAST search: not hits found)

CLC Genomics Workbench 2.0.3
The following has been updated:
- Fixed problems with de novo assembly
- Status properly updated when a conflict is resolved
- Assembly programs now run on older version of Linux
CLC Genomics Workbench 2.0.2
The following has been updated:
- Fixed problems when scrolling very large sequences
- Fixed problem when importing very large GenBank files
- Improved possibilities for navigating contigs
- Improved stability when importing non-standard data
- Improved memory handling and stability of assembly algorithms
- Support for import of Illumina long insert paired-end data
CLC Genomics Workbench 2.0.1
New featuresGeneral performance improvements
- Improved performance when handling large data sets
- Support for reference assembly against the human genome (i.e. reference sequences of any size)
- New and much faster algorithm for assembling short reads (less than 55 nucleotides)
- Significant performance improvements of reference assembly.
- True support for reference assembly of mixed data sets in one go. Sequencing data from different platforms (and both single and paired ends) can now be assembled together. Previously this could be accomplished by making separate assemblies and joining the contigs afterwards, but now this process is automated.
- Reference sequences can be masked based on annotations. This could be used to e.g. mask off repeat regions or only include exons in the assembly. The reference sequences have to be annotated in order to use masking.
- Assembly report includes the number of contigs produced
- Contigs from a reference assembly can also be shown in an overview table. This was previously only possible for De novo assembly. In the last step of the reference assembly wizard, there is an option: Create overview table including all contigs.
- Support for high number of Sanger sequencing data with trace information. Using the Import functionality under High-throughout sequencing you can import huge amounts of e.g. abi files. This will import quality scores but discard trace data to produce a sequence list in the Workbench which makes it possible to assemble thousands of Sanger reads.
- SOLiD import of paired-ends data improved. In some cases paired-ends data also contains single reads which are now removed during import.
- Possible to import cas files created by the CLC NGS Cell (the command-line version of the assembly algorithms of the CLC Genomics Workbench)
- Contigs can be exported in ACE format
- Improvement of ACE file importer
- Trim information in sff files can be used during import
- Support for import of SCARF files (from Illumina Genome Analyzer systems)
- Export of graph data points in csv format
- SNP detection now also reports position relative to the reference sequence as well as the consensus sequence. The table includes both positions per default (can be checked on and off), and the user decides where annotations should be added.
- SNP detection table includes information about the name of annotations covering the SNPs. Previously only the annotation type was reported.
- Trimming now also supports paired-ends data. If one of the reads in a pair is trimmed off, the whole pair will be removed.
- Partially matched reads are reported as a graph along the contig.
- Possibility to open consensus sequence with gaps. Right-click the label of the consensus sequence in the contig view and select: Open Copy of Sequence Including Gaps. The gaps will be represented by Ns in the new sequence.
- Dynamic consensus graph removed from contig view. Since contigs now have a "real" consensus sequence which is also updated to reflect changes in the reads, the dynamic consensus sequence which is switched on in the Side Panel has been removed.
- Annotations can be transferred from reference to consensus sequence in bulk. Right-click one of the annotations and choose "Copy to Consensus Sequence" or "Copy Annotations of Type xx to Consensus Sequence".
- Multiplexing now also possible for paired-end reads
- New plug-in! GFF/GTF support: You can now annotate a sequence using a GFF/GTF file. The plug-in is available for all Workbenches (not CLC Sequence Viewer). Once installed, you find it in Toolbox->General Sequence Analysis-> Annotate from GFF/GTF File. Read more...
- Extract annotations plug-in updated: it now uses the name of the annotation as the name of the new sequence.
- Annotation table has been greatly improved:
- supports very long, heavily annotated genomes
- usability of the filtering has been improved with feedback on the filtering process
- Advanced renaming options.
- Fixed bugs related to contig editing.
- Various bug-fixes.
- Fixed problem with import in 2.0 release.
CLC Genomics Workbench 1.1.1
- Scrollbars can be adjusted manually
- Fixed problems when aligning sequences with lowercase characters
- Fixed import of trace files without quality scores
- Fixed problem when removing location
- A new sequence list can be created from a selection in the table view
- Better memory handling and managment of large contigs
- User definable scrollbar areas for contig views
- A few other minor bugs have been fixed.
CLC Genomics Workbench 1.1
- Increased speed of de novo assembly
- Option of generating a contig table as a result of de novo assembly. This way the workspace is not polluted by a large number of contigs.
- Multi contig table has options for opening contigs or extracting consensus sequences for further analysis
- Much smoother scrolling on contigs when there is very high coverage
- Problems with import of .ACE files
- Problems with excessive generation of files when doing de novo assembly of short read data
- Problems with the use of quality scores in SNP detection
