The Velocity Matrix element
Velocity Matrix (
Velocity Matrix elements contain various table views, described below. See https://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=Working_with_tables.html for general information on working with tables.
Feature Table
The Feature Table () for a Velocity Matrix (
) contains one row for each feature, and has the following columns:
- Name. The name of the feature.
- Id. A feature identifier.
- Type. The feature type.
- Chromosome. The chromosome that the feature is on.
- Region. The region that the feature spans.
Additionally, for gene velocity, as well as imputed spliced and unspliced expressions, the table contains the following columns:
- Min/Max/Avg. The minimum/maximum/average velocity or expression for the feature across all cells.
- Cells w/. The number of cells with a non-zero velocity or expression for the feature.
Clicking on a row opens a separate table, listing the cells expressing the feature.
To create a new matrix element from a row selection in the Feature Table, use the Create Matrix from Selection option in the right-click menu. Cells that express at least one of the selected features are included.
Cell Table
The Cell Table () for a Velocity Matrix (
) contains one row for each cell, and has the following columns for gene velocity, as well as imputed spliced and unspliced expressions:
- Nonzero. The number of features for which the cell has a non-zero velocity or expression.
Clicking on a row opens a separate table, listing the features expressed by the cell.
To create a new matrix element from a row selection in the Cell Table, use the Create Matrix from Selection option in the right-click menu.
Transition Probabilities Table
The Transition Probabilities Table () contains one row for each cell, and has the following columns:
- Sample. The sample that the cell is from.
- Barcode. The cell barcode.
- Non-zero incoming probability. The number of cells with a non-zero probability of transitioning towards the cell.
- Non-zero outgoing probability. The number of cells that the cell has a non-zero probability of transitioning towards.
Clicking on a row opens a separate table, listing the cells with a non-zero incoming/outgoing probability from/towards the selected cell.
