#2000 mag branch 'minigut' is the same sample as modules branch 'bacteroides_fragilis' Issue created by werner291 Hello, people of nf-core. While working on my project to rewrite MaxBin2, I encountered a bit of an odd issue. I was benchmarking a gene caller on two test datasets: the B. fragilis data from the

modules

branch, and the "minigut" data from the

mag

branch. I got identical results on both and dug into why. Turns out the reads are the same file —

test_data/test_minigut_R1.fastq.gz

on

mag

and

data/genomics/prokaryotes/bacteroides_fragilis/illumina/fastq/test1_1.fastq.gz

on

modules

have the same SHA-256 (

sha256-qQ9NSKMVSIbnKlIhuN1rEVnqCQ5dviBjTpZbTugBFqs=

). The contigs are different files but contain the same 272 sequences in a different order Looking at the git history, the reads were first committed to

mag

in 2018 (

2c50b6d5

, "test gut bact"), then the same file showed up on

modules

under

bacteroides_fragilis/

in 2021 (

b2197bc5

). The contigs were re-assembled and added to

mag

in 2023 (

95f022cc

). The naming is what tripped me up — "minigut" sounds like a multi-species gut community, not a single-organism B. fragilis dataset. There's nothing on either branch that connects the two. Maybe worth a note in the mag branch README? nf-core/test-datasets
