Dear @luzhang321
have you solved this issue? I'm also trying to work with this dataset and also run into the same issue with runs missing. There are 1122 Paired-end runs in the Bioproject but only ~400 are recorded in CosteaPI_2017. It seems that there are run files missing.
The reason why there is also Single end files is because the reads were processed with MOCAT which uses paired-end reads and does QC on it. Some reads lose their partner and become "singletons", here recorded as SINGLE.
Best, hans
@paolinomanghi can you comment? The relevant curation file is https://github.com/waldronlab/curatedMetagenomicDataCuration/blob/master/inst/curated/CosteaPI_2017/CosteaPI_2017_metadata.tsv
Hi All
I have created an updated mapping file between samples and runs that uses all paired-end runs (but excludes the singleton files).
Keep in mind that some runs are tagged as paired but when downloaded/extracted using the sra toolkit they become single-end (no clue why). See below for accessions:

Pinging @paolinomanghi - would be great to fix this before the Bioconductor 3.15 release.
Thanks @luzhang321 and @hjruscheweyh for your valuable work.
Hi :)
I fina a difference between ena file and sampleMetadata file in CosteaPI_2017
Here is the example from sample : 713A002-11-0-0 grep 713A002-11-0-0 CosteaPI_2017_KAZ* |less -S |cut -f 1-4,21 CosteaPI_2017 SID713A002-11-0-0 KAZ1 stool ERR1728788;ERR1728787;ERR1728786;ERR1728785
there are only 4 ERRs recorded here. and all of them are single-end.
However when I look into the ena file, 8 enas are recorded. why the pair-end samples are excluded? Cause in the paper, "Library generation and shotgun sequencing were carried out on the Illumina HiSeq 2000/2500 (Illumina, San Diego, CA, USA) platform. All samples were paired-end-sequenced with 100 bp read." they claimed that all of their samples are pair-end.

Why are the 4 pair-end ERRs excluded?
