3.19. Very slow progress through Wizard steps when there are many reference sequences - Genomics WB 6.5 and 6.5.1
For the CLC Genomics Workbench 6.5 and 6.5.1, when working with many thousands of reference sequences, it can take a very long time for each step of the Wizard to load when setting up an analysis. Examples of tasks where this effect is known to exist are:
- Map Reads to Reference
- Probabilistic Variant Detection
- Quality-based Variant Detection
Any analysis involving a reference set including many thousands of sequences is likely to be affected.
Please note that this issue does not affect the analysis itself or the results. It only affects the speed of working through the Wizard when setting up the job through the Genomics Workbench.
This issue was fixed in CLC Genomics Workbench 6.5.2, released in January, 2014.
Workaround for CLC Genomics Workbench 6.5.0 and 6.5.1
The workaround on affected versions is to set up a one-step Workflow for the analysis concerned.
Attached to this FAQ entry are three example Workflows that can be installed and run directly in the Genomics Workbench 6.5 or 6.5.1.
Information on how to create Workflows can be found in our manual starting here:
