0.7.1

openpipelines 0.7.1

NEW FUNCTIONALITY

• integrate/scvi: use nvcr.io/nvidia/pytorch:22.09-py3 as base container to enable GPU acceleration.

• integrate/scvi: add --model_output to save model.

• workflows/ingestion/cellranger_mapping: Added output_type to output the filtered Cell Ranger data as h5mu, not the converted raw 10xh5 output.

• Several components: added --output_compression component to set the compression of output .h5mu files.

• workflows/full_pipeline and workflows/integration: Added leiden_resolution argument to control the coarseness of the clustering.

• Added --rna_theta and --rna_harmony_theta to full and integration pipeline respectively in order to tune the diversity clustering penalty parameter for harmony integration.

BUG FIXES

0.7.0

openpipelines 0.7.0

MAJOR CHANGES

• Removed bin folder. As of viash 0.6.4, a _viash.yaml file can be included in the root of a repository to set common viash options for the project.
  These options were previously covered in the bin/init script, but this new feature of viash makes its use unnecessary. The viash and nextflow should now be installed in a directory that is included in your $PATH.

MINOR CHANGES

• filter/do_filter: raise an error instead of printing a warning when providing a column for var_filer or obs_filter that doesn't exist.

BUG FIXES

• workflows/full_pipeline: Fix setting .var output column for filter_with_hvg.

• Fix running mapping/cellranger_multi without passing all references.

• filter/filter_with_scrublet: now sets use_approx_neighbors to False to avoid using annoy because it fails on processors that are missing the AVX-512 instruction sets.

• workflows: Updated WorkflowHelper to newer version that allows applying defaults when calling a subworkflow from another workflow.

• Several components: pin matplotlib to <3.7 to fix scanpy compatibility (see scverse/scanpy#2411).

• filter/do_filter: removed the default input value for var_filter argument.

• workflows/full_pipeline and workflows/integration: fix PCA not using highly variable genes filter.

0.6.2

openpipelines 0.6.2

NEW FUNCTIONALITY

• workflows/full_pipeline: added filter_with_hvg_obs_batch_key argument for batched detection of highly variable genes.

• workflows/rna_multisample: added filter_with_hvg_obs_batch_key, filter_with_hvg_flavor and filter_with_hvg_n_top_genes arguments.

• dataflow/concat: the --input_id is no longer required when --mode is not move.

• filter/filter_with_hvg: does no longer try to use --varm_name to set non-existant metadata when running with --flavor seurat_v3, which was causing KeyError.

• filter/filter_with_hvg: Enforce that n_top_genes is set when flavor is set to 'seurat_v3'.

• filter/filter_with_hvg: Improve error message when trying to use 'cell_ranger' as flavor and passing unfiltered data.

• mapping/cellranger_multi now applies gex_chemistry, gex_secondary_analysis, gex_generate_bam, gex_include_introns and gex_expect_cells.

0.6.1

openpipeline 0.6.1

BUG FIXES

• src/filter/filter_with_counts: Fix an issue where mitochrondrial genes were being detected in .var_names, which contain ENSAMBL IDs instead of gene symbols in the pipelines. Solution was to create a --var_gene_names argument which allows selecting a .var column to check using a regex (--mitochondrial_gene_regex).

MAJOR CHANGES

• convert/from_velocyto_to_h5mu: Moved to velocity/velocyto_to_h5mu.
  It also now accepts an optional --input_h5mu argument, to allow directly reading
  the RNA velocity data into a .h5mu file containing the other modalities.

• resources_test/cellranger_tiny_fastq: Include RNA velocity computations as part of
  the script.

• mapping/cellranger_mkfastq: remove --memory and --cpu arguments as (resource management is automatically provided by viash).

MINOR CHANGES

• Several components: use gzip compression for writing .h5mu files.

• Default value for obs_covariates argument of full pipeline is now sample_id.

• Set the tag directive of all Nextflow components to '$id'.

BUG FIXES

• Keep data for modalities that are not specifically enabled when running full pipeline.

  thrown when input and output files are defined but not found.

openpipeline 0.5.1

BREAKING CHANGES

• reference/make_reference: Input files changed from type: string to type: file to allow Nextflow to cache the input files fetched from URL.

• several components (except from_h5ad_to_h5mu): the --modality arguments no longer accept multiple values.

• Remove outdated resources_test_scripts.

• convert/from_h5mu_to_seurat: Disabled because MuDataSeurat is currently broken, see https://github.com/PMBio/MuDataSeurat/issues/9.

• integrate/harmony: Disabled because it is currently not functioning and the alternative, harmonypy, is used in the workflows.

• dataflow/concat: Renamed --sample_names to --input_id and moved the ability to add sample id and to join the sample ids with the observation names to metadata/add_id

• Moved dataflow/concat, dataflow/merge and dataflow/split_modalities to a new namespace: dataflow.

• Moved workflows/conversion/conversion to workflows/ingestion/conversion

NEW FUNCTIONALITY

• metadata/add_id: Add an id to a column in .obs. Also allows joining the id to the .obs_names.

• workflows/ingestion/make_reference: A generic component to build a transcriptomics reference into one of many formats.

• integrate/scvi: Performs scvi integration.

• integrate/add_metadata: Add a csv containing metadata to the .obs or .var field of a mudata file.

• DataFlowHelper.nf: Added passthroughMap. Usage:

  include { passthroughMap as pmap } from "./DataFlowHelper.nf"
  
  workflow {
    Channel.fromList([["id", [input: "foo"], "passthrough"]])
      | pmap{ id, data ->
        [id, data + [arg: 10]]
      }
  }

  Note that in the example above, using a regular map would result in an exception being thrown,
  that is, "Invalid method invocation call with arguments".

  A synonymous of doing this with a regular map() would be:

  workflow {
    Channel.fromList([["id", [input: "foo"], "passthrough"]])
      | map{ tup ->
        def (id, data) = tup
        [id, data + [arg: 10]] + tup.drop(2)
      }
  }

  | setWorkflowArguments(
    pca: [ "input": "input", "obsm_output": "obsm_pca" ]
    integration: [ "obs_covariates": "obs_covariates", "obsm_input": "obsm_pca" ]
  )
  | getWorkflowArguments("pca")
  | pca
  | getWorkflowArguments("integration")
  | integration

• mapping/cellranger_count: Allow passing both directories as well as individual fastq.gz files as inputs.

• convert/from_10xh5_to_h5mu: Allow reading in QC metrics, use gene ids as .obs_names instead of gene symbols.

• workflows/conversion: Update pipeline to use the latest practices and to get it to a working state.

MINOR CHANGES

• dimred/umap: Streamline UMAP parameters by adding --obsm_output parameter to allow choosing the output .obsm slot.

• Switch to Viash 0.6.1.

• filter/subset_h5mu: Add --modality argument, export to VDSL3, add unit test.

• dataflow/split_modalities: Also output modality types in a separate csv.

BUG FIXES

• convert/from_bd_to_10x_molecular_barcode_tags: Replaced UTF8 characters with ASCII. OpenJDK 17 or lower might throw the following exception when trying to read a UTF8 file: java.nio.charset.MalformedInputException: Input length = 1.

• dataflow/concat: Overriding sample name in .obs no longer raises AttributeError.

• dataflow/concat: Fix false positives when checking for conflicts in .obs and .var when using --mode move.
