Steps

ID Name Description
workflow_merge_reads Merge paired reads This is workflow specific step and creates a single file object. Also merges reads if multiple files are given. (not interleaving)
workflow_illumina_quality Shortreads quality workflow Quality and contamination filtering of short reads
interleave_fastq Interleave fastq Interleave QC forward and reverse files for subsequent tools
metaphlan MetaPhlAn 4 Profiling the composition of microbial communities
humann HUMAnN 3 HMP Unified Metabolic Analysis Network.
humann_unpack_pathways Unpack pathways HUMAnN 3 Unpack pathways
humann_renorm_table_genefamilies Renorm gene families HUMAnN 3 renormalize genefamilies
humann_renorm_table_pathways Renorm pathways HUMAnN 3 renormalize pathways
humann_regroup_table Regroup unnormalized HUMAnN 3 regroup genefamily
humann_regroup_renorm_table Regroup renormalized HUMAnN 3 regroup renormalized genefamilies
renorm_groups_to_array Merge file arrays Merges arrays of files in an array to an array of files
files_to_folder_normalized Normalized tables Normalized tables folder
out_fwd_reads Output fwd reads Step needed to output filtered reads because there is an option to not to.
out_rev_reads Output rev reads Step needed to output filtered reads because there is an option to not to.
