The Advanced settings include the possibility to set up a proxy server. This is described in Network configuration.
The default location is used when you import a file without selecting a folder or element in the Navigation Area first. It is set to the folder called CLC_Data in the Navigation Area, but can be changed to another data location using a drop down list of data locations already added (see Adding locations). Note that the default location cannot be removed, but only changed to another location.
CLC format data is stored in an internally compressed format. The application of internal compression can be disabled by unchecking the option "Save CLC data elements in a compressed format". This option is enabled by default. Turning this option off means that data created may be larger than it otherwise would be.
Enabling data compression may impose a performance penalty depending on the characteristics of the hardware used. However, this penalty is typically small, and we generally recommend that this option remains enabled.
Internal compression of CLC data was introduced in CLC Genomics Workbench 12.0, CLC Main Workbench 8.1 and CLC Genomics Server 11.0. CLC format files with internal compression are not compatible with older versions of the software. Turning this option off is likely to be of interest only at sites running a mix of older and newer CLC software, where the same data is accessed by different versions of the software.
To work with specific data sets in older CLC software versions, we recommend exporting the data to CLC or zip format and turning on the export option "Maximize compatibility with older CLC products". This is described in more detail in Export of folders and data elements in CLC format.
Without an API key, access to NCBI from asingle IP-address is limited to 3 requests per second; if many workbenches use the same IP address when running the Search for Reads in SRA..., Search for Sequences at NCBI, and Search for PDB Structures at NCBI tools they may hit this limit. In this case, you can create an API key for NCBI E-utilities in your NCBI account and enter it here.
The standard URL for the BLAST server at NCBI is: https://blast.ncbi.nlm.nih.gov/Blast.cgi, but it is possible to specify an alternate server URL to use for BLAST searches. Be careful to specify a valid URL, otherwise BLAST will not work.
It is possible to change the size (in MB) of the Read Mapper reference cache.
The following options are available:
- Use Aspera when available Per default, Aspera is automatically used if installed. This option makes it possible to disable Aspera.
- Limit Aspera download speeds to [ ] Mb/s (Mac and Linux only) Using Aspera may take up a lot of network resources. Use this option to specify a maximum download speed (in megabit per second). Note that this option is only available on Mac and Linux. For Windows users, it is possible to limit the maximum download speed by modifying the
which can be found in
C:\Program Files (x86)\Aspera\Aspera Connect\etc. See http://download.asperasoft.com/download/docs/csrv/3.3.4/linux/html/index.html and http://download.asperasoft.com/download/docs/csrv/3.3.4/linux/html/fasp/setting-global-bandwidth.html for more details.
It is possible to specify an alternate server URL to use for reference data. Reference data set available from the QIAGEN Sets tab in the Reference Data Manager is provided by QIAGEN, and the workbench is configured to download from QIAGEN by default. Unless you are in the special circumstance that your system administrator has decided to mirror this data locally and wishes you to use that mirror of the data, you should not change this setting.
You also have the option to choose to Download reference data to a CLC Server using the Server itself, or the Workbench. It is set by default to CLC Server, and should not be changed unless your system administrator recommends so.
It is possible to Save the login username and password, initiate automatic server login when opening the workbench, and bypass a proxy server.
