#2073 Add clustering test tsv Pull request opened by dbaku42 Add test dataset for pcaclustering This PR adds a new minimal dataset (

test.tsv

) for the

pcaclustering

functionality within the clustering test suite. The dataset is added under:

data/genomics/homo_sapiens/popgen/clustering/

and is intended to support reproducible unit testing of PCA-based clustering workflows. This addition is related to: nf-core/modules#11372 Purpose • Enable robust testing of

pcaclustering

logic in nf-core modules • Provide a minimal, reproducible input dataset for CI and nf-test execution • Ensure compatibility with existing clustering test assets (

test_features.tsv

,

test_clusters.csv

, etc.) Dataset generation The

test.tsv

file was generated from

test.eigenvec

using the following

awk

command: awk 'NR==1 { sub(/^#/, ""); $1 = ""; sub(/^\t/, ""); sub(/^IID\t/, "sample_id\t"); print; next } { $1 = ""; sub(/^\t/, ""); print }' OFS='\t' test.eigenvec > test.tsv nf-core/test-datasets
