Scanpy ComBat (version 1.9.3+galaxy0)

Input object in AnnData/Loom format:

Format of input object:

Format of output object:

AnnData or Loom. Legacy 'h5' datatypes are useful for interacting with older tools. Choosing 'No packaged matrix output' is useful for cases where auxiliary files are generated (like in marker genes). Do not use when there are no other output files, as the tool will generate no output in Galaxy then.

The name of the column in adata.obs that differentiates among experiments/batches.:

Layer to batch correct. By default corrects the contents of .X.:

Comma separated list of additional covariates besides the batch variable such as adjustment variables or biological condition.:

This parameter refers to the design matrix X in Equation 2.1 in [Johnson07] and to the mod argument in the original combat function in the sva R package. Note that not including covariates may introduce bias or lead to the removal of biological signal in unbalanced designs.

Key under which to add the computed results.:

By default a new layer will be created called 'combat', 'combat_{layer}' or 'combat_{layer}_{key_added}' where those parameters were specified. A value of 'X' causes batch-corrected values to overwrite the original content of .X.

What it does

Corrects for batch effects by fitting linear models, gains statistical power via an EB framework where information is borrowed across genes.

Version history 1.9.301+galaxy0: Moves to Scanpy 1.9.3

1.8.1+galaxy9: Fixes version label to get versions sorted properly on Galaxy (equivalent to 1.8.1+3+galaxy0). In addition, adds ability to make fields unique in AnnData operations, adds additional handler on Scrubblet for workflows convenience, enables Scanpy tools to avoid outputing AnnData/matrix files when not required.

1.8.1+3+galaxy0: Upate to scanpy-scripts 1.1.3 (running scanpy ==1.8.1), including a fix to MTX output and a bugfix for the Scrublet wrapper.

1.8.1+2+galaxy0: Upate to scanpy-scripts 1.1.2 (running scanpy ==1.8.1), including improved boolean handling for mito etc.

1.8.1+1+galaxy0: Upate to scanpy-scripts 1.1.1 build 1 (running scanpy ==1.8.1), including improved Scrublet integration with batch handling.

1.8.1+galaxy0: Upate to scanpy-scripts 1.0.1 (running scanpy ==1.8.1), including Scrublet integration.

1.7.2+galaxy0: Upate to scanpy-scripts 0.3.3 (running scanpy ==1.7.2) to incorporate fix for object output from PAGA plotting, to allow PAGA init of FDG.

1.6.0+galaxy0: Update to scanpy-scripts 0.2.13 (running scanpy ==1.6.0) to incorporate new options, code simplifications, and batch integration methods. Jonathan Manning, Expression Atlas team https://www.ebi.ac.uk/gxa/home at EMBL-EBI https://www.ebi.ac.uk/

1.4.3+galaxy10: Update to scanpy-scripts 0.2.10 (running scanpy ==1.4.3) to address bugfixes in run-pca.

1.4.3+galaxy10: Update to scanpy-scripts 0.2.9 (running scanpy ==1.4.3) to address bugfixes in find-variable-genes.

1.4.3+galaxy10: Use profile 18.01 for modules.

1.4.3+galaxy6: Update to scanpy-scripts 0.2.8 (running scanpy ==1.4.3) and wider compatibility with other Galaxy modules. Bug fixes in filtering and plotting improvements.

1.4.3+galaxy0: Update to scanpy-scripts 0.2.5 (running scanpy ==1.4.3).

1.4.2+galaxy0: Update to scanpy-scripts 0.2.4 (requires scanpy >=1.4.2).

1.3.2+galaxy1: Normalise-data and filter-genes: Exposes ability to output 10x files.

1.3.2+galaxy0: Initial contribution. Ni Huang and Pablo Moreno, Expression Atlas team https://www.ebi.ac.uk/gxa/home at EMBL-EBI https://www.ebi.ac.uk/ and Teichmann Lab at Wellcome Sanger Institute.
