Configuring the batch units for Immune Repertoire and Expression Analysis from Reads (10xV(D)J)

The Immune Repertoire and Expression Analysis from Reads (10xV(D)J) workflow requires metadata containing information about the sample of origin and data type: scRNA-Seq or scV(D)J-Seq (figure 19.21). This can be created a priori, or it can imported directly from an Excel or txt file during workflow execution. For more information about Metadata Tables, see http://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=Metadata.html.

Figure 19.21: A Metadata Table associating the reads to samples and data type. The sample of origin is given in the "Sample" column, while the data type is given in the "Type" column, with values "Gene Expression" for scRNA-Seq data, and "V(D)J" for scV(D)J-Seq data. The associated elements are opened on the bottom.

During the workflow execution, it must be configured which metadata columns define the sample: "Iterate over Sample" and data type: "Iterate over RNA and V(D)J", and which values from the data type column correspond to scRNA-Seq and scV(D)J-Seq data, respectively. For more details on configuring workflow execution with metadata, see http://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=Running_workflows_in_batch_mode.html. Make sure to inspect the batch overview to check that the analysis will be performed correctly.

Figures 19.22 and 19.23 show how the workflow should be configured using the input reads and metadata from figure 19.21, and the resulting batch overview is given in figure 19.24.
