Process

`Name`	`QCATCH`

Input 1 channel

#1 tuple

`meta` map	Groovy Map containing sample information e.g. [ id:'test', single_end:false ]
`chemistry` string	Chemistry type for the single-cell experiment, which determines the partition range for the empty_drops step. Supported values: '10X_3p_v2', '10X_3p_v3', '10X_3p_v4', '10X_5p_v3', '10X_3p_LT', '10X_HT'. If using a standard 10X chemistry and quantification was performed with simpleaf (v0.19.5 or later), QCatch will try to infer the correct chemistry from the metadata.
`quant_dir` directory	Directory containing alevin-fry quantification results (af_quant output from simpleaf quant). Must contain the quantification matrix and associated metadata files.

Output 4 channels

#1 report tuple

`meta` map	Groovy Map containing sample information e.g. [ id:'test', single_end:false ]
`*.html` file	HTML QC report generated by QCatch containing visualizations and metrics `*.html`

#2 versions

`versions.yml` file	File containing software versions `versions.yml`

#3 filtered_h5ad tuple

`meta` map	Groovy Map containing sample information e.g. [ id:'test', single_end:false ]
`*_filtered_quants.h5ad` file	Filtered quantification matrix in h5ad format (AnnData) `*_filtered_quants.h5ad`

#4 metrics_summary tuple

`meta` map	Groovy Map containing sample information e.g. [ id:'test', single_end:false ]
`*_metrics_summary.csv` file	CSV file containing summary metrics from QC analysis `*_metrics_summary.csv`
