Figure 1. Add aligner index dialog. If more than one aligner index has not been added to an assembly, the missing aligner indexes will appear in the drop-down list (left). If only one aligner index remains to be added, it will be the only option (right). For many model organisms, automatic downloads are available from the Partek repository
 
Choose the aligner index you wish to add from the drop-down list in the Add aligner index dialog (Figure 1). The following indexes can be added:
  • Bowtie
  • Bowtie colorspace
  • Bowtie 2
  • TMAP
  • BWA
  • SHRiMP 2
  • SHRiMP 2 colorspace
  • Issac 2
  • STAR
  • STAR 2.4 1d
  • GSNAP
  • GSNAP v8


If you are using an assembly supported by Partek (e.g. human), there are three radio button options: Download index; Build index or Import index (Figure 1). Certain aligner indexes may not be available for automatic download because the file sizes are too large to download efficiently.

If available, select Download index and click Create to get the chosen reference aligner index from the Partek repository.

Alternatively, select Build index and click Create to build the reference aligner index. To build an aligner index, a reference sequence file must already be associated with the assembly. Depending on the aligner, you may have to specify further parameters. Consult the user documentation for each aligner for guidance (usually available on-line).

Alternatively, select Import index and click Create to add an aligner index from another source. An aligner index can be added from the Partek Flow Server, My Computer or a URL download link. The behavior of each option is similar to when importing a reference sequence (see Adding a Reference Sequence). When browsing for files on the Partek Flow server, only the files with relevant file extensions will be visible. This will vary for each aligner.

For custom assemblies (e.g. for non-model organisms), only the Build index and Import index options are available (Figure 2).

 

Figure 2. For custom assemblies, automatic downloads are not available so the aligner indexes has to be built or imported
